NFV's Major Movements

Following the initial rush of excitement a few years back, the NFV community has stumbled into the quicksand of operational reality and, despite the best efforts of industry bodies, willing operators and sometimes desperate vendors, it hasn't yet been pulled free. (See Time for a Telecom Reboot.)

But every communications network operator knows that network functions virtualization (NFV) is part of its future, so an NFV implementation strategy is needed. The major problem facing operators, though, is that each one has a unique network and different challenges: Yes, there are many commonalities between them, but each operator has a network with different legacy systems and each one has a different end goal.

But there are a couple of challenges that are universal:

  • Business models: Many of the major challenges for operators come in the form of operational processes, business models and business relationships (how to engage with the suppliers of software and hardware for their virtualization plans). This is a challenge that outgoing Vodafone group head of Network Virtualization, SDN and NFV, David Amzallag, has articulated on a number of occasions but which isn't the main focus of this article. (See Vodafone: The Pricing Isn't Right.)

  • Interoperability: Network operators need to be able to deploy virtual network functions (VNFs) from any developer, be sure they will run seamlessly over the installed NFV infrastructure (NFVi) and interact seamlessly with the installed MANO (management and orchestration) software. (See Together, We Can Build the Telecom 'App Store'.)

If that latter challenge sounds relatively simple, it isn't… currently it's not possible -- the NFV sector is still a set of development islands and the interoperability that operators need seems a long way off.

So where do operators turn for help to solve this problem?

Well, there's no shortage of industry bodies and groups offering up a broad range of help, from advice to specifications to platforms and blueprints. And then there's the vendor community, which has a large number of silver bullets ready to whip out at any given moment. It's just that there's no gun to fire them (yet).

But on the technology planning and implementation side, there are a few key areas where operators can engage with collaborative bodies and independent organizations to further their strategies, particularly when it comes to multi-vendor testing and deciding on an all-important MANO (management and orchestration) strategy. There are also some key starting points for operators as they consider their NFVi (NFV infrastructure) options.

So let's look at some of the key considerations for network operators, including testing and the options available for those seeking an existing MANO that they could deploy.

Testing
Third-party testing has long been a key element in any network operator's technology decision-making processes and there's no reason for that to change. NFV testing, though, is relatively new and the labs that undertake such tasks are, in many ways, developing the blueprints for NFV tests as they engage with the industry.

That's certainly the experience of the team at EANTC, which been undertaking multiple NFV interoperability tests on behalf of the The New IP Agency (NIA). (See 2016 NIA-EANTC NFV Interoperability Test Report and Light Reading Publishes Unique NFV Interoperability Test Report.)

(FYI, the next NIA test undertaken by EANTC will be showcased at the upcoming Big Communications Event (BCE) in Austin, Texas. (See New IP Agency Plans Test for NFV Interoperability.)

Other bodies have also undertaken multi-vendor tests, including CableLabs, ETSI (which holds "plugtests") and OPNFV, which has undertaken assessments in partnership with the University of New Hampshire Interoperability Lab. (See Outstanding Results for the First ETSI NFV Interoperability Test Event, OrbTV: ETSI NFV ISG Plugtest Results, CableLabs Sets Up NFV Interop Lab and OPNFV Nearing Commercial Deployment.)

MANO
The MANO, or management and network orchestration, segment of the ETSI NFV ISG's original architecture was once a sorely neglected space -- for sure, some sort of MANO package could be sourced from commercial technology vendors, but such a move leads to the frantic waving of the "interoperability" and "open" flags.

So what are the non-commercial vendor options? Prior to 2016 there was little for operators to choose from (Open Baton being the exception -- see below) but that lack of options was wildly corrected in 2016, with the arrival of three new efforts, two of which have since joined forces to reduce the dilution of effort.

Here's a brief look at the key offerings:

  • Open Source MANO (OSM): If size is the measure, OSM, an ETSI-hosted open source development, is the most successful -- it has 60 participating companies, not all of whom are ETSI members. Its service provider participants have a strong European bent -- BT, Telefonica, Telenor, Telecom Austria Group and Portugal Telecom are members -- in addition to Verizon, Bell Mobility, Sprint and CableLabs. It recently unveiled its second release. (See ETSI OSM Issues Software Release Two and Open Source MANO Group Adds Verizon, Boasts 60 Members.)

    OSM includes an impressive list of technical features, including native support for multiple virtual infrastructure managers (VIMs) including OpenStack, OpenVIM and VMware Inc. There is support for OpenDaylight and Floodlight OpenFlow-based SDN controllers, but also a plugin model to facilitate addition of future VIMs and SDN controllers, for added flexibility. The software is currently deployed in test labs and was used in the ETSI Plugtest. (See OSM Quick on First Release Trigger.)

  • Open Orchestrator (Open-O): During 2016, the Linux Foundation-backed Open-O Project sought to distinguish itself by having a broader remit than OSM, according to its executive director, Marc Cohn. The group's focus was on end-to-end service delivery, including legacy networks, as part of SUN, its first release which came out in November last year. (See OPEN-O's SUN Rises on Brownfields, Too and OPEN-O Going Beyond the MANO.)

    The Open-O group, which had the weight of China Mobile, China Telecom, Ericsson, Huawei and Intel behind it, was always active in forging collaborative efforts, having been part of the OPNFV's Plugfest last December and working with the MEF to determine how Open-O fits into its Lifecycle Services Orchestration (LSO) effort. At the Plugfest, Open-O was able to successful integrate with OPNFV's Colorado release. (See OPNFV Nearing Commercial Deployment.)

    Then in February this year, a major "MANO Marriage" was announced as Open-O joined forces with the ECOMP development spearheaded by AT&T. (See below.)

  • ECOMP (Enhanced Control Orchestration Management and Policy): Unveiled in 2016, ECOMP is a base of 8 million lines of software code developed internally by AT&T (in collaboration with vendors, most notably Amdocs) and already in live production for the 30%-plus of its functions that are virtualized, giving it instant industry credibility as "live" code and not just slideware. (See AT&T Taps Amdocs as ECOMP Integration Partner.)

    AT&T always said it was keen to share its code and other major operators were attracted to AT&T's efforts, with Orange and Canada's BCE collaborating on the effort. (See Orange to Focus Polish ECOMP Trials on Residential vCPE , Orange Preps ECOMP Trial in Poland, Broadens AT&T Collaboration and Bell Canada to Test AT&T's ECOMP.)

    That sharing strategy took a big leap forward early this year as AT&T announced that ECOMP would be offered up to the open source community via the Linux Foundation. (See Will ECOMP Be the Alpha MANO? and Amdocs: Expect ECOMP Adoption Boomlet.)

    That announcement was shortly followed by the combination of ECOMP and Open-O to form a new group called ONAP (Open Network Automation Platform), which is now focused on how to integrate the code developed by the ECOMP and Open-O teams. The first software release is expected in the fourth quarter of this year. (See MANO Marriage: ECOMP, OPEN-O Converge as ONAP and ONAP Makes Splashy ONS Debut.)

    Chris Rice, senior vice president of Domain 2.0 Architecture and Design at AT&T, noted in February that he expected more operators to join ONAP, and India's Reliance Jio duly obliged, while Ciena added to the growing list of vendor participants. (See Reliance Jio Joins ONAP and Ciena Jumps on ONAP Bandwagon.)

  • Open Baton: In 2015 the Open Baton initiative was launched by two German research organizations (FOKUS and Technische Universität Berlin) as an ETSI NFV MANO-compliant framework that runs on top of Openstack and provides integration between NFV infrastructure platforms and virtual network functions (VNFs). It recently unveiled its third software release.

  • ARIA (Agile Reference Implementation of Automation): ARIA is worth mentioning as a vendor-neutral implementation of the TOSCA (Topology and Orchestration Specification for Cloud Applications) language that can be used for building orchestration systems. ARIA is at the heart of the Cloudify orchestration tool developed by a team at vendor GigaSpaces and is also the TOSCA element in the OPEN-O solution. (See GigaSpaces Launches Cloudify Cloud-Native VNF Program.)

    The growing expectation in the market is that the formation of ONAP will lead to further harmonization of MANO efforts to create a single resource that all operators could turn to -- that would need to involve a merger of ONAP and OSM.

    NFVi
    The situation with NFVi is not as clear cut: Whereas in MANO there are collaborative efforts with an open source ethos, the NFVi territory is more product-oriented.

    The ETSI NFV group developed a blueprint for an NFVi and, from that, some 'hardened' open source-based options are available from the likes of Red Hat and Canonical (Ubuntu), while VMware is also a popular selection for network operators. (See VMware Makes Major MWC Splash, Swisscom Picks Red Hat for OpenStack, Virtualization , Kontron, Canonical Team on Integrated OpenStack Platform and Etisalat Activates NFV Telco Cloud in UAE.)

    The OPNFV initiative, though, is a collaborative industry effort with some major backers: The expectation is that it would offer up an NFVi framework upon which operators could develop their most suitable infrastructure. Its most recent release, dubbed Danube, delivers integration between the NFVi/Virtual Infrastructure Manager (NFVi/VIM) and the OPEN-O system that is now part of ONAP. (See OPNFV's Danube Dubbed 'Milestone' Release.)

    The future
    Obviously, what operators really need is the ability to be able to select the NFVi and MANO that best suits their current situation, future plans and resources and then be confident that they can either deploy third-party (or in-house) VNFs with the confidence that all the piece parts will interoperate and enable them to focus on delivering profitable applications and services to their customers.

    As noted, the industry is still a long way off that point but, five years after the promise of NFV was first dangled like a digital carrot in front of their eyes, there needs to be concrete action in 2017 that makes that virtual promise a hard and fast reality. MANO harmonization and the development of a single API that can bridge the NFVi and MANO platforms look like they would be very welcome developments.

    Re: MANO risks becoming the lock-in that operators feared
    Ask anybody I've worked with -- it's rarely worse than I think. But point taken. I agree that for CSPs, interoperability seems quixotic. But it's a goal that has sustained for decades, and as you say, it's not something that CSPs seem to care much about based on their actions.

    Dennis,

    I think its worse than you think.  (and I thank sj0350 for saying what I have been saying for a couple of years here).  I think Interoperability is a waste of time.  They have essentially taken that out of the current network by their own behavior.  So, the only point of it is to avoid vendor lock-in on a specific component.  Then they go off and essentially single source things and drive second vendors out of business (winner take all RFPs with no reselection after a few years).

    Re: MANO risks becoming the lock-in that operators feared
    Good post, sj. Things would have gone more smoothly if CSPs prioritized their long-term goals. The first goal would have been to virtualize their systems. The second goal -- following after significant progress was made in achieving Goal 1 -- would have been for interoperability. Trying to achieve both simultaneously has resulted in the current perceived stagnation.

    MANO risks becoming the lock-in that operators feared
    I disagree that it's somehow the standards bodies' fault.  The web scale players do just fine without getting wrapped around that axle, fundamentally because they are culturally agile enough to take what they need and build the rest themselves.  

    Carriers like AT&T are doing their best to replicate this with ECOMP/ONAP, but they are currently exposed to the risk of the market choosing an alternative like OSM, leaving them high and dry with a special system that only they use.  (Which would make every vendor charge them more...sort of defeating the purpose of NFV.)

    It's going to come down to numbers now.  If the major carriers coalesce quickly around one platform, the others will fall away and community engagement will increase.  It does not have to be a "RFC"-type standard at this point, because momentum trumps standards.  

    The worst possible outcome is that Verizon stay in one camp, AT&T in another, DT in a third, and so on.  If (say) Verizon and DT joined ONAP, or AT&T and China Mobile joined OSM, we would be done and things would really get moving.
    From The Founder
    NFV's promises of automation and virtualization are intriguing, but what really excites service providers is the massive amount of money they could save.

    Understanding the full experience of women in technology requires starting at the collegiate level (or sooner) and studying the technologies women are involved with, company cultures they're part of and personal experiences of individuals.

    During this WiC radio show, we will talk with Nicole Engelbert, the director of Research & Analysis for Ovum Technology and a 23-year telecom industry veteran, about her experiences and perspectives on women in tech. Engelbert covers infrastructure, applications and industries for Ovum, but she is also involved in the research firm's higher education team and has helped colleges and universities globally leverage technology as a strategy for improving recruitment, retention and graduation performance.

    She will share her unique insight into the collegiate level, where women pursuing engineering and STEM-related degrees is dwindling. Engelbert will also reveal new, original Ovum research on the topics of artificial intelligence, the Internet of Things, security and augmented reality, as well as discuss what each of those technologies might mean for women in our field. As always, we'll also leave plenty of time to answer all your questions live on the air and chat board.
