A Performance Management Reporting White Paper (News - Alert) has been released by the MultiService Forum or MSF. The organization’s findings on end-to-end Performance Interoperability Test Event or P-IOT have been outlined in the White Paper. The P-IOT Event was held from November 8-19, 2010 at the U.S. Government’s National Communications System’s or NCS eXperimental Testbed Environment laboratory.
The ability of Session Border Gateways or SBGs to correctly handle priority traffic was evaluated by the P-IOT 2010. The ability of SBGs to report performance management metrics at both the User-to-Network interface and the Network-to-Network interface or NNI was also evaluated. Analysis of the metrics was conducted to ensure whether the quality of the end-to-end connection can be accurately predicted by the information. The analysis was also conducted to find if the metrics could be used to isolate network faults.
In a release, Frank Suraci, NCS program manager for GETS and WPS said, “The ability to reliably provide quality of service is important for all communications, but it is especially crucial for priority and emergency services.”
According to Suraci, management reporting interfaces under varying load conditions for voice, video, and data sessions can be enabled by testing. The behavior of SBGs under load conditions can be evaluated by the organization with testing. The handling of priority and non-priority/normal sessions can be also specifically investigated by the organization with testing.
In a release, Jim McEachern, president of MSF said, “The importance of interoperability testing is widely recognized by the industry. The IP-NNI in particular is emerging as a key area to enable circuit-to-packet network transformation. The MSF interoperability testing will help vendors improve products, allow service providers to accelerate service deployment, and the MSF to identify standards shortfalls and communicate them to the appropriate standards development organizations.”
SBG functionality and performance management reporting were evaluated by the P-IOT 2010 Event within a single network domain and across two domains. The QoS Key Performance Indicators as defined by the i3 Forum were calculated with the metrics provided by the SBGs. This was done to see if Service Level Agreements between carriers at the SBG’s NNI could be verified with the information provided by one SBG.Calvin Azuri is a contributing editor for TMCnet.
