Information Resources  | 
7/1/2015  | 

THIS CHANGES EVERYTHING

Network Functions Virtualization (NFV) allows the migration of network functions from proprietary, physical hardware to less expensive, more flexible COTS (Commercial Off-the-Shelf) servers. While NFV is not a new concept, it has the power to change the way service providers do business forever. The promise of NFV to generate new source s of revenue lies in the ability to quickly roll out services subscribers want and swiftly eliminate those they don’t.

Service providers that embrace NFV will realize several other advantages including increased operational flexibility and efficiency, and operational cost savings. As more network functions are mi grated to virtual environments, how can operators maintain the same visibility between Virtual Network Functions (VNFs) as they have today bet ween physical network elements? Enter Tektronix Communications’ NFV Service Assurance solution. Our NFV solution delivers proactive, cost-effective assurance for virtual and physical networks.

Since 2010, we have been early 100G client deployment base on the CFP form factor. The module host interface was based on a more conservative 10x10G interface base on established 10G technology. While the CFP form factor is flexible(supporting a wide range of technologies, from 40G serial through 40G parallel and 100G in both 4x25G and 10x10G), its large form factor and relative complex technology keeps it from meeting and density and price expectation required for mainstream 100G.
Pros and Cons of COB in Optical Communication Industry

7/1/2015  | 

COB has become a hot word in optical communication field over the last two years. While racking our brains and exerting all our wisdom to extract value from it, we also need to stay calm and figure out which kind of COB model is more adjusted to optical communication industry. Otherwise it is easy to go astray.

CHIP ON BOARD, or COB, is actually the ‘direct chip attachment on circuit board’ technology. The core processes of COB model consist of DICE BOUND and WIRE BOUND. The former refers to SMT, and the latter means cable tying. Tracing the source, we’ve been aware that COB is not a fresh technology.

Evaluating “The State of the State” of Virtualization
Information Resources  | 
6/30/2015  | 

Welcome to “The State of the State” – a special report from Light Reading and Heavy Reading providing original insights into the changes taking place as CSPs plan their migration to next-generation communications infrastructure.

We know that the entire communications industry is entering a period of incredible disruption – one driven by virtualization, open-source standards, white-box deployments and OTT service delivery.

The information in this package provides both qualitative and quantitative analysis of how these technology change agents are impacting CSPs, including changes to the way they are planning their network configuration, the impact to their investment and supplier choices and how service providers’ specific procurement criteria is changing in the face of new service requirements.

As Patrick Donegan, Heavy Reading’s chief analyst, points out in his report, “New Requirements for Network Equipment Vendors,” many of the attributes of next-gen CSP networks already exist in high-end “cloudified” enterprise networks. This is prompting CSPs to look for new attributes in their equipment suppliers, including both IT and systems integration experience.

Our survey of more than 130 service providers contains some genuinely fascinating insights into their plans. For example, we now know from the service provider survey that more than half of all CSPs are still at the stage of researching virtualization, but 100% of them know they have no choice other than to make the move to NFV eventually.

The payoff for doing so will be agile, virtualized networks that allow them to reinvent themselves as services innovators, building and launching profitable new applications and services at will. And the pressure is on them to make this move before their last-generation networks and business models are rendered obsolete by new competitors. At the same time, our report shows that CSPs clearly recognize the migration must be made in an orderly fashion, and in a way that doesn’t disrupt or destroy existing revenue streams.

Disruptors come in various sizes and forms – and some from perhaps unlikely places. I’m hoping these findings start some very interesting conversations this week.

Service Orchestration Requirements for a New Era of Networking – by Heavy Reading
Information Resources  | 
6/30/2015  | 

Although software-defined networking (SDN) and network functions virtualization (NFV) are associated with driving a new era of networking, they are in fact responses to customer demands for faster delivery of network services. Every business on the planet is being affected by the need to compete faster and exploit new market opportunities ahead of their rivals. Enterprises are turning to the cloud for the agile infrastructure that boosts operational speed. However, they also need connectivity and associated network-based services to be delivered in similar time scales.

A number of operators are already responding to their customers' hyperfast business requirements by rolling out "programmable network" services, also known as userdefined networks, or network as a service (NaaS). Such services are underpinned by an ability to configure (activate), dynamically and on demand, physical and virtual network elements – in other words, physical and virtual network functions, or PNFs and VNFs.

The key technology that supports on-demand activation of network elements is known as service orchestration. Service orchestration is a fashionable term that is broadly interpreted in ways that are causing considerable confusion. A particular area of misunderstanding is the relationship between a service orchestration system and the NFV Management and Orchestration (MANO) stack. Service orchestration is complementary to SDN and NFV, and is a critical capability for the new era of virtualized networking.

Because service orchestration is interpreted so widely, it is important that operators understand the basic principles that an effective and efficient service orchestration system should support. This paper examines the drivers for service orchestration and the three "extreme" business requirements for flexibility, automation and reliability emerging in a new era of hyperfast business that a service orchestration system must fulfill. It explores the capabilities that a service orchestration system should have to meet these requirements.

Section II looks at the impact of a cloud-driven pace of business on the network and customer requirements for the rapid delivery of network services.

Section III discusses the three "extreme" requirements for programming the network successfully.

Section IV describes the principles that operators need to look for in a future-proof service orchestration system that can coexist with a changing OSS and NFV management landscape.

Software-Defined Networking - Discover How to Save Money and Generate New Revenue
Information Resources  | 
6/30/2015  | 

Abstraction helps simplify development or modification of new or existing services and applications, and that simplification drives costs down and contributes to faster revenue returns. Many people in the industry advocate the relocation of control functions to centralized general-purpose servers, typically x86 class in data centers. This approach offers lower costs through the use of lower-priced, mass-produced hardware for the forwarding devices.

In addition, the SDN community is discussing how service providers can use SDN to make money. These discussions typically include three main methods:

  • Repurposing existing revenue-generating network services onto a software-defined network that promises greater flexibility and a lower cost structure, resulting in higher margins
  • The ability to modify or spin up services much faster, capturing new opportunities to enhance revenue
  • A lower-cost, more-flexible network, which can promote more application innovation in a dynamic service environment, opening new markets
Evolved Programmable Network Solution Overview

6/30/2015  | 

Service providers already face enormous demands on their network and data center assets from exploding mobility, video, and cloud-based applications. We are now in the era of the Internet of Everything (IoE) that will accelerate new metrics of scale never seen before. How can service providers reduce costs and improve efficiency and resource usage, even as they expand their business for new revenue-generating services?

According to The Cisco Visual Networking Index™ (Cisco VNI™), global network transformations will be accelerated by exponential growth in IP, cloud, mobile, video, and machine-to-machine (M2M) traffic growth. IP traffic alone will grow 300 percent to 1.4 zettabytes annually by 2017. With exponential growth comes opportunity. Cloud service providers have changed the rules of an age-old service-delivery game. Profitability is about rapidly delivering customer-focused, application-based services over lean, agile, automated IPv6 cloud-based networks.

In response to this game-changing shift, traditional telecommunication service providers will evolve their business models by taking advantage of innovations in software-defined networking (SDN) and Network Function Virtualization (NFV) technologies. Rewards of evolution will include intelligent flexibility for offering real-time repurposing of physical and virtual infrastructure - allowing providers to monetize and accelerate service delivery and capitalize on their unique link to the consumer and the data center.

Sponsored by Accedian

The phrase “embarrassment of riches” sprang to mind when I saw the speaker line-up for this year’s Big Telecom Event (BTE) in Chicago. Among the names taking the stage and sharing real-world, industry-changing developments were:

 • Andre Fuetsch, Senior Vice President, Architecture & Design, AT&T
 • Axel Clauberg, Vice President, Aggregation, Transport, IP & Fixed Access, Deutsche Telekom AG
 • Jack Waters, CTO, Level 3 Communications
 • Jared Wray, SVP of Platform, CenturyLink
 • Bikash Koley, Principal Architect & Manager, Network Architecture, Google

And there were many more...

What’s important at an event such as BTE is that these respected and experienced individuals deliver useful insights to their peers, as well as confirming to the industry – including customers, partners and investors – that they are indeed market leaders and innovators.

And they did.

The content of this report shows how much there was to learn and take away from BTE, and this is just a snapshot of the peer-to-peer learning that was on offer. The focused panel sessions on topics as diverse as hybrid network management and orchestration, the role of IoT tech in smart cities, dealing with DDoS attacks, the introduction of cloud DVR and 4K services were all designed to provide useful insights and data points for attendees.

What is clear, though, is that the path to future prosperity in communications networking is still a steep and tricky one to navigate: Never before have network operators and service providers been faced with so many critical decisions that could make or break their companies and even careers.

As Light Reading’s CEO Steve Saunders noted in his BTE opening keynote address, the telecom industry as we know it is over, finished…. But what is replacing it is something much bigger and more exciting.

This report will help to provide some idea about where the industry is going. We hope you find it interesting and useful.

Nominum Case Study: Large ISP Gains Visibility & Control During DDoS Attack
Information Resources  | 
6/15/2015  | 

Extraordinary spikes of randomized queries greatly stressed resolvers compromising performance & increasing support calls.

A large South American ISP seeking more secure, resilient and efficient DNS infrastructure upgraded their servers from open source to Vantio CacheServe several years ago. Vantio worked flawlessly, reducing operational strain and improving the subscriber experience with fast, low latency DNS resolution that complemented their high performance network.

In early summer 2014 a DNS based DDoS attack that had been plaguing the Internet substantially escalated when the volume of attack related queries jumped 400% overnight. The attack uses randomized subdomains prepended to target domains, as shown in an example query below.

wxctkzubkb.liebiao.800fy.com
random target name

This provider started seeing extraordinary spikes of randomized queries at their resolvers. Because names with randomized subdomains are never in-cache, resolution required more computationally expensive recursion, which stressed provider resolvers. Authoritative servers for target names failed or responded slowly under the load.

Nominum had kept the provider informed of DNS DDoS developments for several months and was immediately prepared to help. In less than one week the provider went from attacks having measurable network impact and high operational stress, to protections that adapted as the attacks changed each day.

Thousands of open home gateways made way for billions of unwanted queries during attacks, compromising network integrity & threatening provider reputation.

Successful DNS transformation yielded immediate benefits for this provider. Nominum’s demonstrated competence elevated them to partner, taking responsibility for the ongoing DNS evolution. Additional projects are being discussed to take advantage of innovative N2 applications to better engage customers, promote new services, and gather network and subscriber insights.

Nominum Whitepaper: The Costs of a DNS Outage
Information Resources  | 
6/15/2015  | 

Internet access has become an essential part of everyday life. Regulation of Internet services may differ around the world but there is universal acceptance of the necessity for secure, highly available Internet access. Regulators recognize their obligation to ensure a positive subscriber experience in return for the fees that subscribers pay. The regulatory action taken for this outage is not an outlier; it will rapidly become the new baseline for regulatory oversight around the world.

Stealthy, powerful DNS-based DDoS techniques are motivating providers to deploy defenses. Vantio ThreatAvert throttles DNS-based DDoS attacks using Precision Policies and the Global Intelligence Xchange (GIX) to identify and optionally mitigate malicious activity. Precision Policies precisely block DDoS related queries while protecting legitimate queries. The Global Intelligence Xchange (GIX) is based on more than a Terabyte of DNS data collected daily and processed by an expert research team to identify and validate new DDoS and other threats. GIX is continuously updated in real time and automatically distributed worldwide.

6/15/2015  | 

New challenges make managing DNS harder than ever. Operational resources are always scarce and DNS based DDoS attacks compromise infrastructure and expose subscribers. Next generation DNS servers can positively impact network economics. Scalable performance minimizes hardware and operations costs. Unified policy allows for fine grained management of query traffic. Detailed data collection without impacting performance strongly complements other network data supporting decision making.

Nominum’s Vantio CacheServe has been the gold standard for DNS resolution for more than a decade, offering exceptional availability, extraordinary stability, and superior security. Vantio CacheServe 7 changes the game again. A new software architecture coupled with time-proven Vantio technology maximizes the power of server hardware, letting providers “do more with less” with their DNS.

  • Leading performance yields recurring infrastructure savings
  • Unified Precision Policy framework enables adaptive security and new kinds of DNS based applications
  • Embedded data collection enriches operations and business teams for minimal cost and modest effort

Responsive 24x7 “commercial grade” support, staffed with experts immersed in provider requirements ensures networks always deliver the quality Internet experience subscribers demand.

Nominum Whitepaper: New Best Practices for DNS
Information Resources  | 
6/15/2015  | 

DNS is a critical network element and operational Best Practices have been around a long time. Most provider DNS operations team have already covered the basics – limiting access to resolvers to internal IP ranges, carefully monitoring server operating parameters, moving servers closer to users and other necessary care and feeding.

But new challenges make managing DNS servers harder than ever. DNS-based DDoS continues to compromise infrastructure and operational resources are always scarce. It’s time to do more with less, a few new Best Practices can help:

  • Take advantage of policy to manage DNS traffic
  • Use dynamic threat lists to track today’s dynamic exploits
  • Collect DNS data, network wide, all the time
  • Use the data to produce operational intelligence

Responsive 24x7 “commercial grade” support, staffed with experts immersed in provider requirements ensures networks always deliver the quality Internet experience subscribers demand.

Nominum Whitepaper: Overview of DNS-Based DDoS
Information Resources  | 
6/15/2015  | 

DNS-based DDoS has rapidly evolved over two years and there is no indication it will stop. Lists of IP addresses of the very large installed base of home gateways with open DNS proxies are available on the Internet, as are turnkey DDoS services that use them. The recent transition to bot driven DDoS malware changes the landscape. Malware infected home gateways are already widely used with devastating impact as are cameras capable of powerful DDoS attacks. It’s likely DDoS malware is highly portable so other devices may be inducted, which could mean as the Internet of Things flourishes it may bring with it unwanted baggage.

Stopping malicious traffic at ingress to DNS resolvers is the best way to address DNS-based DDoS. It prevents attacks from working while minimizing processing work for resolvers. Authoritative servers never see malicious queries. ISP networks and the ultimate targets of DNSbased DDoS are protected. Fine-grained filters and dynamic threat lists are needed to protect good queries while blocking bad ones. Strong foundational capabilities will consistently stand up against fast changing attacks and continue to adapt as attacks evolve.

eBOOK: Making the most of SDN and NFV with Ubuntu OpenStack
Information Resources  | 
6/1/2015  | 

Over the past decade, the IT industry has undergone radical, disruptive change in the form of virtualisation. Its adoption – and that of its revolutionary descendant, cloud computing – has transformed the datacentre.

Several forces lie behind this shift, including:
   • The desire for faster scalability and ondemand computing
   • Downward pressure on infrastructure and management costs
   • Competitive demands to get new applications to market faster

These drivers have led to a rise in the demand for open source cloud solutions in the enterprise, with OpenStack emerging as the leading platform.

New problems mean new opportunities

The very same issues are now emerging in the telecoms industry, which means network operators need to make similar architectural advances. But telco networks often comprise large, siloed, proprietary platforms that can be hard to manage and scale.

Cost and complexity can be amplified if hardware-based appliances are dedicated to performing single functions on the network.

These appliances typically have short lifecycles and consume large amounts of space and power. The good news is that they are ripe for replacement by virtual technology.

With the growth of multimedia applications, mobile and IoT causing an explosion in network traffic, while revenues from new services prove ever-harder to come by, technologies like SDN and NFV offer the potential for telcos to unleash new capabilities. With the right platform and tools, the telecoms industry can see new levels of agility, just as IT did before it.

Is this ebook right for me?

This ebook addresses the implementation of software-defined networking (SDN) and network functions virtualisation (NFV) on carrier-grade IT architecture, using the world’s leading open source cloud platform, Ubuntu OpenStack.

Canonical, the software vendor behind Ubuntu OpenStack, does not produce SDN or NFV applications itself. But in developing, supporting and backing Ubuntu OpenStack, the company is uniquely positioned to assist telcos wrestling with how best to implement these technologies.

If you’re involved in the design of systems architecture for the telecoms industry, this ebook is for you.

5/19/2015  | 

When designing Network Functions Virtualization (NFV) solutions, some software providers approach the problem of high availability through application-level redundancy schemes (load balancing, check pointing, journaling, etc.). But application-level high availability by itself doesn't achieve the goal of five-nines (99.999%) reliability—the standard set by service providers using traditional network infrastructure based on physical equipment. In this paper, find out how to ensure five-nines availability for services delivered in an NFV implementation.

  • Streamlining Order Delivery of Next-Generation Business Services – By Heavy Reading
    Information Resources  | 
    5/7/2015  | 

    Competition in the communications industry is intense, and service providers are looking for the next big thing to differentiate themselves from their competitors. As traditional communications service revenues decline, service providers are seeking new revenue streams by focusing on innovative applications, cloud-centric strategies, interactive video-centric services, machine-to-machine (M2M) services, network functions virtualization (NFV) and software-defined networking (SDN). Another trend that service providers see as a potential growth engine is delivering business services for their enterprise and small to midsize business (SMB) customers.

    Technology evolutions such as SDN and NFV are being adopted by global operators, with an initial focus on business services. Since enterprise and SMB are currently viewed as the strongest potential growth engine for operators, it is easier to prove the business case on newer virtualization technologies such as NFV and SDN, where these technologies can be used to reduce time to market and lower opex and capex in order to launch services for their most profitable segment.

    The current industry attention being paid to SDN and NFV stems from the promise of hardware vendor independence, improved operational efficiency, standardized and open interfaces and the dynamic chaining of network and IT functions to create new “integrated” services. In a recent Heavy Reading survey, service providers cited reducing opex, new services monetization and improved resource utilization as the leading benefits of NFV implementation to their networks.

    Challenges of Power Measurement During 100G Service Turn-up
    Information Resources  | 
    4/27/2015  | 

    CFP-based 100G Ethernet deployments present new challenges with respect to the skills and tools required to support them. While these deployments often require a WDM interfaces, which vary greatly from traditional interfaces, additional turn-up costs can occur; Optical Spectrum Analyzers (OSAs) are needed to verify the CFPs in place as well as the training and support that are critical in carrying out OSA measurements. However, solutions for 100G Ethernet service testing are available to mitigate these issues.

    EXFO’s latest whitepaper, entitled “Challenges of Power Measurement During 100G Ethernet Service Turn-up,” describes how traditional turn-up activity differs from today’s approaches, 100G service deployment challenges, and how an intuitive OSA—which is typically not used in Ethernet turn-up activities—can actually become an essential and cost-effective toolkit for field engineers.

    Deployment Strategies for 40G/100G: Trade-Offs and Impacts
    Information Resources  | 
    4/27/2015  | 

    When it comes to deploying high-speed 40 Gbit/s or 100 Gbit/s technologies, today’s operators must choose which type of architecture will support the new wavelengths. Will they opt for a “brownfield” deployment, which uses an existing network, or a “greenfield” deployment, which employs new or unused fibers?

    While both approaches offer their own pros and cons, they come with a very different price tag. They can also bring specific technical issues—such as inter-channel crosstalk, cross-phase modulation or the “cohabitation” problems of coherent and non-coherent channels—that will affect proper signal transmission more or less depending on the parameters of the network architecture. In addition, although brownfield deployments are less expensive since they rely on existing fiber and network components, they do not promise the kind of easy scalability that greenfield deployments do.

    In the end, operators must factor in all these technical, financial and long-term-planning aspects and make the best decision. Tough call? This paper provides key insights to help them decide which way to go.

    DNS Security for Service Providers: An Active Approach at L7 - by Heavy Reading
    Information Resources  | 
    4/8/2015  | 

    In the evolution to all-IP, the DNS has become a critical network protocol. In all but the smallest service provider networks, these transactions are now taking place at the rate of millions per second.

    Because of its importance, a company's DNS infrastructure has for some time been one of the favorite targets of hackers. The attack type traditionally associated with the DNS has been a Distributed Denial of Service (DDoS) attack, which overloads the servers with an overwhelmingly large volume of communication requests, thus rendering them unavailable to legitimate service requests.

    The motivation and organization of attackers has changed fundamentally. Whereas early attackers tended to be isolated individuals that bore a grudge or were just social misfits, today's attackers are far more organized, much greater in number and far more heavily resourced – including organized crime, terrorist organizations and even nation states. Attack tools have also been greatly simplified, so that the expertise needed to leverage them is much less than it used to be. Many attack tools are also available online at low cost.

    As a result, attackers are investing a lot of resources in finding new ways to attack and manipulate DNS resources for criminal ends. Not only are attackers finding new ways to overwhelm the DNS resources of businesses and services providers and render them inoperable. They are also leveraging and manipulating the DNS protocol itself as one of the most effective attack vectors for the exfiltration – stealing – of highly valuable, proprietary information from consumers and businesses, including service providers themselves.

    Driving Customer Loyalty Through Network Service Quality – by Heavy Reading
    Information Resources  | 
    3/31/2015  | 

    Loyal customers are valuable; churn is costly. These observations have become axiomatic and most communications service providers (CSPs) are conscious of the need to improve customer loyalty as measured by indicators, such as Net Promoter Scores (NPS).

    According to Heavy Reading research into wireless CSPs, they widely agree that network service quality is the top driver of customer loyalty, trumping customer care and price, especially for high-value customers. They have made good progress in understanding the "outside in" view of customers towards their organizations. They routinely collect customer satisfaction data through a variety of channels and many already use NPS. They also feel they have satisfactory visibility into network service quality, although Heavy Reading research finds that the number of CSPs who say they have an excellent view of their network is still relatively small.

    However, CSPs strongly aspire to go further: to invest in improving their understanding of network service quality and its impact on customer loyalty. They recognize that such knowledge can help them reduce churn and optimize customer lifetime value, target network investment accurately, launch successful marketing campaigns or prevent the degradation of service performance in the first place, avoiding the high operational costs of dealing with customer issues reactively.

    CSPs with mature customer experience management (CEM) initiatives already have a strong ability to correlate customer loyalty and network service quality and are investing most aggressively in improving it, for example, by investing in big data- driven "next-generation" CEM architectures and analytical applications.

    However, CSPs starting out on their CEM journeys have also identified this as a key capability. They have an opportunity to leapfrog "first-generation" CEM tools and approaches with a second-generation CEM solution.

    This white paper reviews the finding of recent Heavy Reading research into wireless CSP attitudes to and plans for driving customer loyalty through control of network service quality. It discusses the features needed in a next-generation CEM solution that will support a real-time understanding of the impact of the network on individual customers' experience, enabling CSPs to take appropriate actions to maintain both loyalty and profitability.

    Section II looks at why network service quality matters to customer loyalty and CSP attitudes to improving it.

    Section III expands on the principles of a next-generation CEM architecture.

    Small Cells – Big Impact

    There is no doubt we are attached to our mobile devices, to the point where they now outnumber the global human population. Mobile data will increase 1000-fold between 2014 and 2020, with users expecting service quality to keep in step. RF capacity has its limits, and is unable to keep up with demand unless a new radio access model emerges.

    Mobile access networks are strained to maintain quality as more subscribers run bandwidth-intensive applications from a variety of devices. With the annual throughput of mobile traffic expected to increase from 58 Exabytes in 2013 to roughly 335 Exabytes by 2020, brute-force over-provisioning of bandwidth is no longer an economically feasible solution. Operators must implement strategies to meet growing quality of experience (QoE) expectations even in the face of finite spectrum.

    Small cells are the answer to dramatic mobile traffic growth, but new challenges in the backhaul accompany them. Small cells allow operators to spatially share precious spectrum, operating inside the macro cell footprint and effectively bringing the network closer to the majority of users indoors and in highly dense urban areas. Unlicensed spectrum, including WiFi, also relieves licensed-band saturation, and small cells typically employ multiple technologies to scale their capacity.

    The solution is as effective as it is necessary. Mobile operators will deploy 5 million small cells annually by 2017, where over half of mobile traffic will be carried by more than 62 million small cells worldwide. ABI Research forecasts 125% year-on-year growth of units shipped in roughly the same timeframe for a $3.6 billion market.

    SkyLIGHT(TM) VCX Controller
    Information Resources  | 
    3/31/2015  | 

    SkyLIGHT™ VCX Controller is the industry’s first performance assurance controller employing Network Function Virtualization (NFV) to bring advanced monitoring capabilities network-wide, without the need for expensive, high-end test equipment.

    This radically more efficient approach to network performance monitoring combines all the benefits of virtualization without compromising test speed or precision. By eliminating key cost, scalability, and coverage barriers to network performance visibility, service providers can now more cost-effectively ensure a better quality of experience (QoE) for users.

    The VCX Controller works together with Accedian’s Nano smart SFP (optical transponder) and compact gigabit Ethernet Modules to deliver multi-flow traffic generation and ability to monitor the performance of thousands of flows. The Modules are easy to install and cost up to 90% less than existing solutions, enabling service providers to realize the significant capital and operational efficiencies promised by an NFV architecture, while their customers benefit from a fully assured network.

    Designed to fit seamlessly into a service provider’s existing infrastructure and operational practices and procedures, the VCX Controller uses the same interfaces as Accedian standalone solutions to interoperate openly with standards-based network elements, management platforms, analytics platforms, and more.

    The result combines centralized control with distributed firepower. This approach is unique in its scalability, and its ability to openly interface network-wide intelligence with existing infrastructure, management, and control platforms.

    VoLTE Performance Assurance
    Information Resources  | 
    3/31/2015  | 

    As operators roll out VoLTE, QoS issues can quickly degrade, interrupt or prevent calls and roaming.

    In a world where “5-bars” performance is expected anytime & anywhere, anything less impacts customer loyalty and revenue. VoLTE MOS & R-Value, Latency, delay variation, availability, and packet loss are just a few key metrics that must meet demanding specs for successful VoLTE services.

    A real-time view of network performance lets operators respond quickly to QoS threats - and offer the best possible VoLTE experience to their customers.

    NFV's Biggest Barrier: Overcoming the Operations Challenge – by Heavy Reading
    Information Resources  | 
    3/30/2015  | 

    NFV promises to enable greater flexibility in network design and operation, supporting the deployment of virtual network functions (VNFs) in new locations to reduce cost and optimize service delivery. But the ability to install, move and manage new VNFs in a timely way is only one dimension of network flexibility. Operators are also looking for greater service agility - the ability to deliver services on demand, not only across VNFs but also across traditional network elements, since physical network infrastructure is not going to disappear for the foreseeable future.

    Service flexibility and agility across both physical and virtual infrastructure requires a new approach to service fulfillment and assurance. In February 2015, the Metro Ethernet Forum (MEF) issued a white paper that coined the term Lifecycle Service Orchestration (LSO) to describe the combination of capabilities needed to support the agile definition, fulfillment and assurance of end-to-end services across a hybrid network infrastructure.

    LSO spans both existing operations support systems (OSSs) and the NFV Management and Orchestration (MANO) stack, bridging the gap between them. LSO needs to sit on top of existing OSSs today to manage the portion of services supported by physical network elements. However, to the greatest extent possible, the objective is to evolve away from legacy OSSs as more of the network is virtualized.

    On its own, however, the NFV MANO does not deal with end-to-end service lifecycle management. Its focus is the orchestration of the NFV Infrastructure (NFVI) and the instantiation and lifecycle management of VNFs – the virtual equivalents of individual network elements or groups of network elements that chained together create a complex network function, such as an Evolved Packet Core (EPC).

    End-to-end understanding of services resides at LSO level: LSO contains an inventory of the services that it is managing and orchestrating, and it associates a service with its underlying resources, whether these are provided by a physical network element, a VNF or a third party provider.

    This paper adopts the MEF's LSO terminology and explores LSO's purpose, relationship with ETSI NFV MANO and required set of capabilities.

    Section II expands on the drivers for network flexibility and service agility.

    Section III examines the requirement for LSO, its relationship with OSSs and the NFV MANO and fulfillment and assurance use cases that demonstrate their interaction.

    Section IV looks at the high-level capabilities that LSO should implement.
