MARKHAM, ON -- During the Interoperability showcase [which highlighted multiple products from 14 MPLS & Frame Relay Alliance members] at the MPLS World Congress 2004 in Paris, Navtel launched support for MPLS Differentiated Service - Traffic Engineering (DS-TE) for both routing and signaling control protocols. This allows vendors and carriers to test multiple classes of differentiated services concurrently while characterizing customer service level agreements (SLAs) by utilizing wire rate QoS generation/analysis.

Diff-Serv-aware Traffic Engineering extends MPLS Traffic Engineering by enabling networking devices to perform constraint-based routing of “guaranteed” traffic. This results in a more restrictive bandwidth constraint than that provided by standard CBR for regular traffic. “The ability to satisfy a more restrictive bandwidth constraint translates into an ability to achieve higher Quality of Service performance (in terms of delay, jitter, or loss) for the guaranteed traffic. Support for DS-TE is crucial to the deployment of QoS sensitive applications such as carrier class voice over packet networks using VoIP” said Paul Scarff; Navtel’s IP Product Manager.

Navtel's award winning InterWatch platform provides testing for Next Generation converged Networks (NGcN) with integrated routing and signaling functionality along with concurrent IP QoS and RTP wire rate traffic generation and analysis to test NGN application such VoIP over packet networks. The DS-TE testing complements Navtel’s in-depth NGcN test product portfolio.
