IP Infusion Expands Its ZebOS Advanced Routing Suite With Multicast, IP Routing Redundancy, And BGP Virtual Routing Support

San Jose, Calif., June 6, 2002 – IP Infusion, a leading provider of intelligent network software for enhanced IP services, announced today the availability of version 4.0 of its ZebOS™ Advanced Routing Suite (ARS). IP Infusion has broadened its already widely used and comprehensive advanced IP routing and switching offerings to now include multicast, IP routing redundancy, and BGP virtual routing solutions.

"This 4.0 release adds IP redundancy to our ZebOS Advanced Routing Suite (ARS) by extending our routing protocols to support multiple control planes, which is critical for high availability support in both the wireline and wireless equipment markets," said Nick Keating, President and CEO of IP Infusion. "In addition, our routing solution now offers multicast support through a PIM-SM module. By broadening our BGP module with a virtual routing extension, we currently support OSPF and BGP virtual routing, which enables service and equipment developers to deliver secure routing technology in a single communication solution. This significantly lowers both capital and operational expenses for service providers needing to provision multiple solutions by eliminating the need for multiple boxes."

About Advanced Routing Suite Version 4.0 Features
IP Routing Redundancy Software Module
The IP Redundancy module provides communication between a primary and a secondary control plane through extensions to the ZebOS Network Services Module. The primary and secondary control planes both run the Advanced Routing Suite. Upon normal operation the primary control plane version of the ARS services routing updates and requests. If the primary fails, the secondary control plane quickly discovers its failure and takes over operation of all routing functions. During normal operations, a carbon copy of the primary Routing Information Base (RIB) is maintained in the secondary control plane. This allows routing to be quickly and seamlessly carried out even in the event of hardware or software failures. The IP Routing Redundancy software module also provides a series of APIs that enables any redundant application to integrate with and to function properly within a redundant system using the ZebOS ARS.

PIM-SM Routing Module
IP Infusion's Protocol Independent Multicast-Sparse Mode (PIM-SM) module routes multicast packets to multicast groups, and is designed to efficiently establish distribution trees across wide area networks (WANs). PIM-SM is called "protocol independent" because it can use the route information that any routing protocol enters into the multicast Routing Information Base (RIB).

BGP Virtual Routing
The BGP 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.

About IP Infusion's ZebOS™ Routing Suites
IP Infusion designs, develops, and markets its ZebOS™ family of advanced IP routing suites, which are based on a unique, modular, multi-process architecture featuring control-plane components that provide route redistribution and conversion, management services, and an OS/processor abstraction layer for routing and switching modules. This high-performance routing software features IPv4 and IPv6 versions of OSPF, BGP, and RIP routing protocols; MPLS, BGP-VPN, RSVP-TE, and CR-LDP switching and signaling protocols; and Mobile IP and virtual routing support. ZebOS 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 dependent modules to quickly build on Linux, BSD, Solaris, VxWorks, OSE, and other popular operating systems. Processor support for Intel® Pentium, Motorola® PowerPC™, Sun® Sparc™, and MIPS are provided.
