MARKHAM, Ontario -- With release 5.3.2 of its InterWatch, Navtel introduces a leading carrier-class performance benchmarking application for VoIP control, data and transport planes. The release is built around three major features and addresses the test requirements of converged, multiservice data and voice networks based on IP/MPLS standards.

The first feature of release 5.3.2 for VoIP is the level of control plane performance and scalability available from one InterWatch system. Depending on the protocol, one InterWatch can generate up to 17.8 million BHCA at 480 calls/second per port. It scales up to 256,000 end-points per test system. InterWatch VoIP control plane test applications include conformance, functional, performance interoperability and scalability testing. The InterWatch supports a wide range of protocols such as MGCP, SIP, MEGACO and SIGTRAN.

Another major feature is the release of RTP (Real-time Transport Protocol) and VQT (Voice Quality Testing) generation and analysis packages, the second building block of the control, data and transport plane InterWatch test system.

The final major feature is the vastly enhanced IP QoS real-time test suite which is a significant component of Navtel’s converged network test solution. The InterWatch QoS test suite is designed to perform automated analysis of the mapping/re-classification of the DUT/SUT regardless of the classification/marking capabilities invoked and the congestion management, avoidance; shaping and policing implemented within the DUT/SUT. This functionality can be used in conjunction with the MPLS DS-TE control information supported to provide support for carrier class VoIP across an MPLS backbone. The release also supports ATM Label type as well as the "Generic Label" type support for MPLS over ATM as defined by RFC3035. This allows MPLS networks to utilize the core capabilities of ATM while simultaneously adding a packet router infrastructure to optimize traffic engineering to support voice.

With 5.3.2, Navtel's InterWatch enables network equipment manufacturers to benchmark their systems and assists service providers in determining whether their network can be the longed-for multiservice common network, usually built around a MPLS core.

Stéphane Attal, President of Navtel commented that "our leading edge solution coupled with the company's desire to exceed customer expectations has resulted in major global carriers implementing release 5.3.2 from the outset with others looking to follow that lead".
