Net tester quickens triple-play services validation

Agilent Technologies Inc. has announced that its Network Tester integrates real-world application traffic generation with comprehensive passive analysis and distributed test capabilities. The Agilent Network Tester now allows 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.

As part of triple-play service infrastructure deployment, network operators test complex multivendor network systems that deliver value-added services. Equipment manufacturers mirror these test scenarios in customer Proof of Concept labs.

The traditional approach to active system testing generates traffic via the network infrastructure, with measurements being 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. To analyze and eliminate the degrading effects of individual components, operators must run additional tests for each network element.

The N5557A Network Tester, with its ability to combine intrusive testing with passive analysis, decouples traffic generation from performance and QoE measurements. Network Tester, while generating realistic mixes of triple-play traffic, uses the integrated Agilent J6900A Triple-play Analyzera passive analysis toolfor independent data collection, performance and QoE analysis around critical system components. This approach delivers instant and holistic insight into performance and QoE of the complete network system, as well as into its critical elementsall from a single test tool, in one test scenario. This allows network operators to troubleshoot, optimize and bring triple-play service delivery systems online and to market in minimal time.

The Agilent Network Tester is already available. Pricing starts at approximately $30,000 for a high-performance N4192A traffic module equipped with four GbE test ports.
