Palo Alto, Calif.Test-and-measurement house Agilent Technologies has four new and upgraded test-and-management approaches that address the convergence of voice, video, and data.
These so-called triple-play tools are slated to assist service providers, network equipment manufacturers, and cable providers to ensure performance and reliability of next-generation networks.
The tools help analyze an end user's QoE (quality of experience, a key factor in accelerating the adoption of new services. Furthermore, these new products improve productivity and QoS (quality of service).
They also promise to shorten the time needed to isolate problems, as well as reduce the overall time needed for triple-play services deployment. Here’s an overview; be sure to click on the links at the end of this article to access more details.
Validate Performance, Scalability
For starters, Agilent's N2X multi-services tester provides the capability for validating performance and scalability characteristics of next-generation triple-play network equipment. Using it, you can emulate real-world usage scenarios.
The system provides insight into the QoE of each individual subscriber's service while the network is fully loaded with traffic. This permits the testing of new network architectures and elements in ways that closely resemble the end-user's triple-play service experience.
Next in the new tools line-up is the Agilent Network Tester. It's billed as an application and security tester for triple-play. The latest version supportsas an industry-firstthe emulation of thousands of proprietary-application users, while also being able to measure their impact on delay-sensitive voice and video application performance.
Agilent Network Tester provides insight into an application-aware device's system performance limits, simultaneously emulating multiple denial-of-service attacks. It can also enable verification of an end-customers' QoE, even under adverse conditions.
Next in the line-up of new tools from Agilent is a distributed network analyzer. The Agilent Distributed Network Analyzer PRO lets you access the critical QoE of customers to isolate root causes.
The Distributed Network Analyzer PRO offers a variety of access interfaces in a portable platform. It uses a breakthrough WLAN (wireless local area network) user interface, making it an extensible tool for diagnosing network and services issues when tuning-up and optimizing networks.
New triple-play measurements include support for HSDPA (High-Speed Downlink Packet Access) in mobile broadband networks, video protocol analysis, and an industry-first capability of directly correlating VoIP (voice over Internet Protocol) voice quality with network impairments. That promises to take the guesswork out of analysis.
The last new triple-play tester from Agilent is its NgN Analysis System for end-to-end VoIP cable monitoring. Agilent's probe-based non-intrusive monitoring and troubleshooting system for VoIP networks offers end-to-end call and performance analysis that can let service providers drill down to troubleshoot QoE problems.
Agilent's extension of its NgN Analysis System now addresses the needs of cable VoIP service providers to ensure high QoS. Through the added support for COPS (common open policy service) protocol and for Cedar Point Softswitches, the system displays end-to-end call flow records for advanced performance metrics, and realtime and historical call analysis.
