IP Infusion Delivers MPLS Layer 2 Virtual Circuit (Martini Draft) Support

San Jose, CA, August 8, 2002 – IP Infusion, a leading provider of intelligent network software for enhanced IP services, announced today the availability of version 4.2 of its ZebOS™ Advanced Routing Suite (ARS). IP Infusion has expanded its advanced IP routing and switching solutions to now include MPLS Layer 2 Virtual Circuit support. The MPLS Layer 2 Virtual Circuit feature is fully integrated into the ZebOS ARS product and complements IP Infusion's current MPLS BGP-VPN capabilities. This source code software solution is also integrated with IP Infusion's OSPF, BGP, RIP, and IS-IS protocol modules.

"This 4.2 release adds support for the IETF's Martini draft standard to our ZebOS Advanced Routing Suite (ARS) family. Martini draft is one of the most widely used draft standard protocols on an MPLS network," said Nick Keating, President and CEO of IP Infusion. "Support of this feature will assist service providers and telecommunications customers in delivering VPN services. IP Infusion now has both Layer 2 and Layer 3 MPLS-VPN support, which provides the flexibility that our OEM customers need to deliver full support to their customers."

About Advanced Routing Suite Version 4.2 Features
MPLS Layer2 Virtual Circuit Module
The ZebOS Advanced Routing Suite (ARS) MPLS Layer 2 Virtual Circuit (VC) is an implementation of two IETF Martini drafts, l2circuit transport and l2circuit encapsulation. It encapsulates Ethernet frames from a local LAN, at the MPLS ingress, into an MPLS LSP tunnel and de-encapsulates at the PE egress. MPLS Layer 2 VC enables customers to extend their LAN across an MPLS WAN transparently.

The MPLS Layer2 VC is modular source code software to assist OEM customers to deliver their products in a timely manner to market. It is fully integrated into the ZebOS Network Services Module (NSM) and the ZebOS LDP protocol modules. It is written in ANSI C and has been ported to a variety of operating systems.
