Agilent Technologies Enhances NgN VoIP Analysis System
By Anuradha Shukla, TMCnet Contributing Editor
Agilent Technologies has announced the release of its enhanced NgN Analysis System (NgNAS), which retains all of NgN's Voice-over-IP (VoIP) management capabilities but has been reengineered to handle huge increases in the volume of complex VoIP traffic.
The new release also includes real-time voice quality monitoring with industry-unique capabilities. This solution has been designed for service providers that are challenged with network operation problems. By accelerating troubleshooting at all levels of network operation, the enhanced NgNAS prevents problems from escalating, maintains subscriber satisfaction, and significantly cuts costs.
This new cost-effective solution allows even non-experts to troubleshoot and quickly diagnose problems within complex, high-volume VoIP/IMS networks.
The product has been launched in response to the need of wireline and wireless service providers that are moving from traditional Time Division Multiplexing (TDM) to VoIP in stages. These clients need to manage up to 50-percent VoIP growth a year and search for a solution that allows them to do so in a cost effective manner.
Agilent also points out that a number of carriers are also implementing VoIP in IP Multimedia Subsystem (News - Alert) (IMS). While some want to deliver brand-differentiating IP services, others do it for purely practical reasons related to enhancing VoIP reliability. But all this is not easy to accomplish since signaling across a VoIP network -- especially an IMS VoIP network -- is far more complex than in a traditional circuit-switched network.
Todd Biddle, general manager Agilent's Network Solutions (News - Alert) Division/Assurance explains the problems associated with this situation: "During a peak hour, 33 million calls might traverse a network of 60 switching sites. Each call may require 50 messages to complete, so that comes to about 1.6 billion messages an hour. If only one of those messages goes astray, a call may fail. To troubleshoot the cause successfully, the operations team must find that single message -- the proverbial 'needle' in an enormous 'haystack.'”
Agilent’s (News - Alert) solution has the ability to quickly reduce the haystack to a vastly smaller grouping of suspect messages. Once this goal is accomplished the solution then goes on to provide additional tools for locating the precise problem.
“It's all about finding and acting on that one message in a billion.”
Agilent Technologies (News - Alert) also launched the CTS-1000 automated WirelessHD test system, the industry's first solution for the WirelessHD compliance test. The solution has been designed specifically for manufacturers of WirelessHD modules and chipsets for consumer and computing products.
