IP INFUSION RELEASES ITS ADVANCED ROUTING SUITE WITH VIRTUAL ROUTING, MPLS TRAFFIC ENGINEERING AND MOBILE IP SUPPORT

March 7, 2002, San Jose, California - IP Infusion, a leading provider of advanced networking software for the development of next generation communications, networking and wireless equipment, announced today the availability of an enhanced version of its Advanced Routing Suite (ARS). As one of its most comprehensive software suite releases, ZebOST ARS Version 3.0 includes Virtual Routing, RSVP-TE, CSPF, and Mobile IP Home Agent Discovery support.

"Our newest version of the Advanced Routing Suite adds MPLS traffic engineering to our MPLS-VPN suite and is fully integrated with our routing protocols through a unique CSPF topology update module," said Nick Keating, President and CEO of IP Infusion. "The new 3.0 version also offers a Virtual Routing (VR) source code module that allows edge equipment to securely support multiple users without the increased cost and footprint associated with using multiple routers. While, with our Mobile IP Home Agent Discovery we offer additional features to our growing list of wireless base station customers."

About Advanced Routing Suite Version 3.0 Features
Virtual Routing
The Virtual Routing (VR) source code module allows service providers to provision existing dedicated services to customers without incurring related overhead cost by consolidating multiple routers into a single router. Each customer receives a dedicated virtual router as opposed to a dedicated physical router. As a result, multiple VRs can exist inside a single physical router. VR helps with equipment footprint and all its associated costs. Each VR is a separate instance of the routing protocols and has its own management interface.

Resource ReSerVation Protocol with Traffic Engineering extensions (RSVP-TE)
RSVP-TE signaling is widely used to setup Label Switch Paths (LSPs) in a MPLS cloud and is fully compliant with RFC2205, RFC2210, RFC3209, and RFC 3210 as well as implementation of Hello Messaging. IP Infusion's RSVP-TE has been tested successfully for interoperability with many of the existing router vendors such as Juniper Networks, Cisco Systems, and Foundry Networks.

OSPF with Constrained Shortest Path First (CSPF)
The OSPF/Constrained Shortest Path First (CSPF) module calculates an optimum explicit route (ER) based on the specified constraints, using Traffic Engineering Database (TED) and pre-existing LSPs. The resulting ER is used by a signaling protocol, such as RSVP-TE, to setup LSPs. Currently, our CSPF module can be linked to our OSPF-TE module, and together with RSVP-TE module provide a full Traffic Engineering solution.

Mobile IP Home Agent Discovery
IP Infusion now supports Mobile IP via the implementation of Home Agent (HA) Discovery. A Home Agent is a node on the home network that provides reach ability for a Mobile Node (MN) to its home address even when the mobile node is not attached to its home network. IP Infusion's Network Services Module(NSM) maintains HA lists by gathering the Router Advertisement (RA) messages that has a HA bit on from other HAs on the same home link for the Dynamic Home Agent Address Discovery.

About IP Infusion's Advanced Routing Suite
The Advanced Routing Suite (ARS) is based on a unique, modular, multi-process architecture, which is built around the NSM. The NSM provides route redistribution and conversion, management services, and an OS/processor abstraction layer for both the routing and switching modules. Protocol modules for OSPF, BGP, and RIP for IPv4 and IPv6 use the services of the NSM to provide routing table information and updates. In addition, MPLS modules for LDP and the MPLS Forwarder use the NSM for central management and routing integration. The ARS, which can be used in embedded equipment and as a route server on standard server platforms, contains a number of features that ensure that device and system developers can quickly bring IP routing and switching software to market.

IP Infusion's software suites can be delivered as either portable, platform-independent source code, or in server solutions, which can be used to support proprietary systems and includes a number of OS dependant modules to quickly build on Linux, BSD, Solaris, VxWorks, OSE, and other popular operating systems. Processor support for Intel® Pentium, Motorola® PowerPCT, Sun® SparcT, and MIPS are provided.
