Who Makes What: Test & Measurement Gear for Next-Generation Networks

Welcome to another Light Reading project aimed at helping everybody get a better understanding of a rapidly evolving marketplace – in this case, test and measurement (T&M) gear for next-generation networks (NGNs). While NGNs can embrace almost anything that isn’t traditional circuit-switched TDM, they are understood here to be the packet-oriented (basically IP) broadband networks supporting converged multimedia applications, such as VOIP and IPTV.

As with previous Who Makes What reports, this article proposes a taxonomy, lists vendors, and invites readers to suggest improvements, point out omissions, and generally lend a hand in building a comprehensive view of what is going on in terms of products and vendors.

CALL TO ACTION: A questionnaire to enable vendors to categorize their products using the taxonomy of this Who Makes What can be downloaded by clicking on this link.

DEADLINE: Please submit your entry BEFORE Jan 31, 2006, to make sure your company’s products are included in the launch version of the directory.

Here’s a hyperlinked summary of the remainder of this report:

  • Page 2: Overview of NGN T&M
    Provides a big picture of what testing and measurement are needed in NGNs, and how this Who Makes What classifies the main types of product.

  • Page 3: Consolidated Vendor List
    Shows all the vendors so far included in the taxonomy pages, and invites readers to name vendors that should be included in this survey or comment on vendors already listed. This is intended to be a growing list, and we don’t claim to have included everybody from the start. So please let us know who’s missing.

Test and measurement are becoming big practical issues for carriers and service providers as NGN services such as VOIP and IPTV start to become mainstream, and there is growing demand for VOIP T&M equipment from all types of service providers and carriers.

One sign of NGN T&M’s increasing maturity is the emphasis now being given to carrier-class systems and products for assessing real-time service performance and quality, in contrast to established products and tools aimed at the lab or standard field-engineering metrics. Frost & Sullivan estimates, for example, that the market for VOIP call monitoring will increase nearly sixfold to about $300 million between 2004 and 2011. (See F&S Reports on VOIP Monitoring.)

NGNs and NGN services often give scope for different product classifications, and T&M is no exception. Some vendors (often those with extensive product lines covering all areas of telecom and even other industries) classify their products by key technology. Others classify by application (usually defined fairly generally), and others use a combination of the two. On top of all this, the dominance of software in NGNs makes functional integration in some form or another virtually universal, so the boundaries between functional categories are often blurred.

This report uses a different approach – perhaps drill-down would be a good name – to emphasize the shift in carrier and service-provider interest toward real NGN services, and therefore operations-oriented T&M. It is based on the idea of starting with the end result that the customer sees – the service – and then digging down further into the layers of software and infrastructure supporting it. So it looks like this, with four broad categories arranged from top to bottom as:

  • Service T&M: Covers (a) how users perceive the service (subjective quality, etc. – e.g., Is the VOIP call audio quality acceptable?); and (b) how the service is performing technically (QOS, objective performance characteristics, parameter measurements, etc. – e.g., Why does the audio quality sound awful? Are we meeting the SLAs?).

  • Network Application T&M: Covers how the network application is performing technically (what’s going on with the technology immediately supporting the service – e.g., all the VOIP components, protocols, etc., that provide IP telephony).

  • IP Network T&M: Covers how the IP network is performing technically (as a whole, in terms of getting packets from A to B – e.g., packet jitter and loss).

  • Access and Transport T&M: Covers how the underlying specific access and transport technologies are performing technically.

Obviously there is a connection with standard network layering, but it’s by no means an exact correspondence, and there is a lot of crossover. Typically, some vendors are beginning to build what might be called vertical T&M stacks – systems and products that aim to cover all the bases by providing tailored metrics across all these categories, either for specific areas of carrier operations, such as triple play or VOIP, or for all converged services as a whole. Figure 1 illustrates this idea.

Generally, this report anchors such products in the Service or Network Application categories, because this is where the most service-specific technology is located, but their functions can go both up and down through the other categories. Some products are listed under several categories.

Such vertical stacks, especially the larger ones, usually integrate with existing operational support systems (OSSs) and back-office applications, such as fault management, provisioning, and trouble-ticketing systems. This leads into the wider area of service and performance management systems.

Equally obviously, further categories could be added below Access and Transport T&M to get further into the detail of the various network Physical Layers (such as Sonet, GigE, WiMax, raw optics, and so on), but this would broaden the coverage so much that the NGN service focus would be lost, even though T&M at this level remains crucial to NGN functioning. However, a certain amount of coverage of these Physical Layers inevitably creeps into products classified here as Access and Transport T&M because of the crucial role of the Physical Layer.

Another broad category, aimed more at equipment development and evaluation than network operations, is Lab Gear. This covers such activities as equipment design and feature verification, conformance testing, interoperability testing, load and stress testing, and installation and acceptance testing. Inevitably there is some crossover between T&M equipment used as lab gear and that used in network operations and maintenance. For simplicity of presentation, this report lists T&M products intended mainly as lab gear in a single list.

This page lists all the vendors so far included in the various categories of the taxonomy. It is an initial list only, and we know that it cannot be complete. So please alert Light Reading to any missing names (and don’t be upset if your company has been omitted inadvertently!).CALL TO ACTION: A questionnaire to enable vendors to categorize their products using the taxonomy of this Who Makes What can be downloaded by clicking on this link.

As some vendors have a very large number of individual products for specific purposes over the whole domain of next-generation test and measurement, only a selection can be given in the following lists, and many related products have been subsumed under a generic family heading.

Strictly, Service T&M handles two different (but related) types of service assessment:

  • Subjective service performance and quality

  • Objective service performance and quality

However, many T&M products in this category are tightly integrated with functions for Network Application and IP Network T&M.

Live monitoring of VOIP traffic becomes very important as the volume of traffic grows, because carriers need to be aware of quality problems before they become significant. Quantitative measures (such as MOS) can be monitored automatically and used to trigger alarms if preset thresholds are crossed.

Voice-quality testing can be active or passive – test signals can be injected into the network and monitored (active), or characteristics of existing traffic can be monitored (passive).

Web applications now involve dynamic multimedia content, and IP devices (such as switches, firewalls, and load balancers) have to be increasingly content aware. Web T&M therefore has to extend across Layers 4 to 7.

Subjective service performance and quality measures and assesses how users perceive service output, such as speech, audio/music, and video. The crucial issue is to relate objective measures of service performance and quality to users’ subjective experiences of service quality. This is done usually by software scoring algorithms based on international standards (for example, from the ITU) and extensive databases of the results of human tests. The aim is to keep any objectively measured signal degradation introduced by the NGN to within acceptable subjective limits.

These T&M products have two main modes of use:

  • Real-time service monitoring (for example, monitoring VOIP call quality)

  • Pre-deployment testing for network and service dimensioning and troubleshooting

Typical products comprise controlling hardware and software, and distributed probes and device monitors (which may be pure software or firmware, and fully integrated into end devices or network components). Probes and monitors can be active (using special generated test signals) or passive (using natural traffic only).

Products in this category frequently integrate test and measurement of objective service quality, together with network application and network IP performance, to give a comprehensive real-time monitor of user QOS and SLAs, and to aid network diagnostics. Such products frequently merge with service and network management systems.

Objective service performance and quality covers how the service is performing in terms of various engineering metrics, some of which will be specified in SLAs and QOS guarantees. Products in this category are concerned with fundamental service characteristics – for example, VOIP call setup times, numbers of blocked or dropped calls, and conformance to voice-signal specifications.

As with subjective service quality, products can be integrated with network application and network IP performance, to give a comprehensive real-time monitor of service QOS and SLAs, and to aid network and service diagnostics. Such products frequently merge with service management systems.

The presentation of VOIP quality results is important within a carrier and service provider organization if they are to be used most effectively. Different departments (e.g., customer services and field engineering) have different requirements. Modern testing systems increasingly allow results to be presented and used in different ways.

Network Application T&M covers specific network technologies (or technology combinations) used to deliver specific NGN services – for example, VOIP to deliver voice telephony and IPTV to deliver TV. This category of T&M is thus heavily concerned with the application protocols and other technology specifics.

Triple Play

Triple-play converged voice, video, and data services involve several technologies and many different metrics for performance. Ixia, for example, characterizes these as including:

  • Transport Network – Data Plane: Jitter; latency; throughput; Mean Opinion Score (MOS – measure of voice quality); Media Delivery Index (MDI – measure of video quality)

  • Transport Network – Control Plane: routing capacity; convergence times; failover times; multicast performance

  • Subscriber Edge Services: Subscriber scaleability (PPP); channel-change latency (IGMP/MLD; join/leave); IP address management (DHCP scaleability); QOS policy marking; authentication scaleability; VOIP signaling scaleability

  • Content Network Testing: Video stream capacity; video server response; VOIP call server handling capacity; VOIP call setup rate; data concurrent session capacity; data connection setup rate

VOIP

VOIP testing is complex because so many protocols are (or can be) used in a VOIP network (vendors report instances of around 50 protocols being specified in some RTTs, for example). And it is necessary to test a lot of the protocols used to get a good view of the user experience.

The characteristics of the underlying IP network are crucial to the performance of NGN applications and services. While IP Network T&M is long established, the high-bandwidth, real-time, multimedia nature of many NGN applications and services emphasizes different aspects than do traditional data communications. QOS metrics are particularly important, and these have to be made and related at, not only at Layers 2 and 3, but also at higher layers.

IP network T&M issues include:

  • IP Packet Loss: This clearly affects VOIP quality. But it is much more audible if the traffic is bursty. Packet latency, as it grows, leads to increased echo. Excessive packet jitter will cause packets to be dropped from equipment buffers, and therefore packet loss will increase.

  • Echo: It is very difficult to detect echo by just looking at the IP signal; telcos really have to look at the (reconstructed) analog voice signal.

  • Audio Volume: This is not normally an IP network issue (the voice audio volume is encoded in the packet data). But RTP used in VOIP can be monitored as a way of handling network issues (and a new extension to RTP is being developed to handle this better).

    Multicasting is important in applications such as video conferencing, distance learning, streaming media, and video over IP, but places big demands on routers and switches.

    DSL and cable modems currently form the backbone of the broadband access networks needed for NGN applications and services. These are large, high-density installations, and need to be tested efficiently for Layer 2–3 performance, PPPOx performance, and user QOS under real traffic conditions generated by higher-layer protocols.

    DSL testing covers a wide range of DSL flavors, such as ADSL2+/ADSL2/ADSL, G.SHDSL, HDSL2, IDSL, SDSL, VDSL.

    Broadband access is beginning to move to various flavors of FTTx and Ethernet.

    Products in this category are intended largely for equipment design and feature verification, conformance testing, interoperability testing, load and stress testing, robustness and stability testing, or installation and acceptance testing. Major systems offer considerable functional and feature integration, with large protocol libraries and network-simulation capabilities.

    There is inevitably some crossover between this and the other categories.
