Nortel Networks introduced key IP VPN enhancements for its Passport portfolio of multiservice switches enabling service providers to offer business-class intranet IP VPN services with IP Class of Service (CoS)/Quality of Service (QoS), Diffserv, bandwidth guarantees, IP accounting and auto-discovery capabilities. The rollout includes two new VPN Extender Card modules and software enhancements designed to scale IP VPN services to thousands of VPNs per node. The first VPN Extender Card enables Passport 20000 and Passport 15000 Multiservice Switches to support up to 600 VRs or Virtual Routing and Forwarding tables (VRFs) via dedicated processing and memory. The second card, designed for Passport 7000 Multiservice Switches, can support up to 250 VRs/VRFs. New software enhancements to Nortel Networks' portfolio of Passport multiservice switches provide additional IP/MPLS functionality and enable service providers to offer more stringent SLAs by reducing or eliminating carrier core IP-route re-convergence times. Nortel Networks said the new capabilities ensure non-stop forwarding and non-stop routing of IP data traffic during a hitless software migration or switchover of the IP control plane for static and dynamic IP routes.

- Nortel Networks' Passport 20000 is a multiservice core switch designed to scale to 160 Gbps in aggregate capacity. It is positioned to enable service providers to migrate their ATM networks toward IP/MPLS. The Passport 15000 Multiservice Switch is a high-capacity, carrier-grade switch that supports IP VPN, ATM, Frame Relay, MPLS, circuit emulation and voice services. The Passport 7000 Multiservice Switch also supports similar capabilities in a smaller format.
