Agilent offers triple-play test with traffic generation and passive analysis

APRIL 15, 2008 -- Agilent Technologies Inc. asserts that its Network Tester is the first in the industry to integrate real-world application traffic generation with passive analysis and distributed test capabilities.

APRIL 15, 2008 -- Agilent Technologies Inc. (search for Agilent) asserts that its Network Tester is the first in the industry to integrate real-world application traffic generation with passive analysis and distributed test capabilities.

The company says its Agilent Network Tester now enables service providers and network operators to quickly and cost-effectively validate performance and quality of experience (QoE) of triple-play services in network infrastructures that span wide geographic areas.

The traditional approach to active system test generates traffic via the network infrastructure, with measurements performed on the test instrument interfaces. This approach, while sufficient for validation of a complete system performance or QoE, provides little insight into bottlenecks imposed by individual system components, Agilent says. To analyze and eliminate the degrading effects of individual components, operators must run additional tests for each network element.

The N5557A Network Tester now decouples traffic generation from performance and QoE measurements. The unit, designed to generate realistic mixes of triple-play traffic, uses the integrated Agilent J6900A Triple Play Analyzer (a passive analysis tool) for independent data collection, performance, and QoE analysis around critical system components.

Agilent says this approach delivers instant and holistic insight into performance and QoE of the complete network system, as well as into its critical elements -- all from a single test tool, in one test scenario. This allows network operators to troubleshoot, optimize, and bring triple-play service delivery systems on line and to market in minimal time, the company concludes.

The new Network Tester software release includes:


  • real-time MOS and MDI measurements on a per stream, per call basis for triple-play QoE analysis
  • the ability to decode, view, and listen to any voice and video stream in test traffic for instant service-quality assessment
  • integrated end-to-end test capability for performance and QoE analysis of distributed network infrastructures
  • a wide range of natively supported triple-play applications, including multiple flavors of VoIP, VoD, IPTV, and Internet data, as well as integrated network access protocols for subscriber realism.

The Agilent Network Tester is available now. Pricing starts at approximately $30,000 for an N4192A traffic module equipped with four Gigabit Ethernet test ports.
