Agilent Extends NgN Analysis System to Improve QoS for VoIP Providers

9/22/2005 - Agilent Technologies Inc. (NYSE: A) announced the extension of its industry-leading NgN Analysis System to monitor and support improved quality of service (QoS) for VoIP session border controlled networks. The solution monitors session border control traffic by assembling and correlating all signaling associated with complex IP peering VoIP calls, which gives service providers visibility into their subscribers' entire service experience. Agilent's NgN Analysis System enables quick identification and resolution of VoIP call control and quality problems, reducing customer defection to competitors through improved QoS.

Primarily used as dynamic firewalls between IP networks to keep unwanted and malicious VoIP traffic off networks, session border controllers (SBCs) also capture detailed QoS metrics that can be used in service assurance applications. Because SBCs serve as both the source and destination for all media streams and signaling messages entering or exiting the provider's network, the data captured and then analyzed by NgN Analysis System can quickly determine the quality of a VoIP call that is coming into or out of a network and the network that introduced the voice quality degradation.

"NgN Analysis System helps service providers reduce customer churn by quickly identifying and resolving VoIP call control problems," said Tom Walls, vice president and general manager of Agilent's Assurance Solutions Division. "With our product's support for VoIP networks, one service provider has reported that the time to resolve network problems has been reduced by over 90 percent. The comprehensive call analysis enables this provider to address customer-affecting problems more quickly and with fewer personnel."

QoS is improved by NgN Analysis System's ability to proactively identify call failure issues network-wide. It proactively monitors key quality of experience metrics at the SBC to baseline, threshold and alarm on voice-quality problems in real time on every call. Key metrics such as packet loss, delay and jitter are analyzed for every call that crosses the SBC, providing an overall view of the network's QoS.

Complete call flow records show the signaling interaction between all key network elements, enabling technicians to pinpoint network anomalies. The product's concise and intuitive presentation of the customer's end-to-end experience is a result of correlation of VoIP protocol messages into a single call flow record to provide network-wide visibility.
