The MSF Certification Program will focus on areas of critical interest to both vendor and service provider members of the MSF, addressing key issues necessary to deliver multi-vendor practical open architecture solutions for Next Generation Networks (NGNs). The pilot programme, scheduled for Q4 this year, will concentrate on verifying the technical components of RTCP implementations in media gateways and SIP end points, and the accuracy of the network statistics that they report.
The RTP/RTCP protocol addresses the measurement and reporting of network quality for real-time applications such as VoIP and any differences in implementation or faulty reporting between the very large number and types of nodes running these protocols would seriously degrade the network operation and damage application performance.
Commenting on the programme's strategy, Roger Ward, office of the CTO, BT Group, and president, MSF, said, "Getting the variability out of RTCP implementations was the favourite starting point with our members for this programme, and working the detail of the pilot with a major test house such as Iometrix will establish the critical processes and procedures necessary to deliver a major ongoing MSF Certification Program to the industry. Subsequent stages, starting early next year, will address detailed aspects of SIP interconnect between two or more providers - and will follow naturally from this pilot phase."
The NGN network components subject to certification in the pilot phase include SIP endpoints and SIP phones, residential gateways (CPE), access gateways, trunking gateways, media servers and session border gateways. The test scenarios include point-to-point calls as well as complex calls, verifying that a mixer maintains the correct RTCP statistics for each RTP sessions it supports. Also, when a destination endpoint is changed, verifying that the end-point clears the statistics for the old media path and reports the statistics accurately for the new media path.
Stressing upon the urgency of this certification programme, Bob Mandeville, president and founder, Iometrix, said, "It's sheer arithmetic: traditional telephony was built around barely a half dozen basic systems, whereas with VoIP, for example, we have literally hundreds of systems and suppliers. So there's a significant risk of non-conformance within any service provider network - let alone the problems of calls spanning multiple networks. The opportunity to use certified equipment is a major step towards seamless NGN coverage."
Registration for the initial pilot testing programme opens immediately, and vendors are invited to contact Iometrix at msf-certification@iometrix.com latest by 31 August 2007. |
