IP INFUSION ANNOUNCES THE AVAILABILITY OF ITS ZEBOS ADVANCED ROUTING SUITET, THE INDUSTRY'S FLAGSHIP, PORTABLE NETWORKING SOFTWARE

April 3, 2001, San Jose, CA - IP Infusion, a leading supplier of portable networking software announced today that it has begun shipping its ZebOS Advanced Routing Suite, the industry's most advanced software solutions designed for networking, communications, and wireless developers.

"The availability of off-the-shelf network technologies is spawning a revolution in the development of routing and switching platforms for the core, edge, and access device markets. Vendors developing these platforms need off-the-shelf, portable networking software that provides support for the increasingly complex standards of the internetworking and communication markets. It is simply too costly and time consuming to develop this software from scratch. The ZebOS Advanced Routing Suite provides these vendors with modular, platform independent support for both IPv4 and IPv6 versions of popular routing protocols such as OSPF, BGP and RIP," said Nick Keating, President and CEO of IP Infusion. "The ZebOS Advanced Routing Suite has been designed to support standard operating systems and platforms and to be able to easily integrate with next generation network processors and ASIC's."

The ZebOS Advanced Routing Suite contains a unique, modular, multi-process architecture built around the Network Services Module. Protocol Modules for OSPF, BGP, and RIP for both IPv4 and IPv6 communicate with the Network Services module to provide routing table information and updates. The Network Services module maintains a central routing information base, performs route conversion, route redistribution, and configuration management for the Protocol Modules. The ZebOS Advanced Routing Suite has a platform independent, modular, architecture, which allows all or portions of the suite to be easily integrated into switch and router platforms.

"What really makes this software unique is that it is built for support of both existing and future internetworking protocols," added Keating. "We offer one of the industry's first dual IPv4 and IPv6 routing solutions. We will continue to support leading edge IETF standards and protocols. This commitment is critical to our customers who are continually adding services to their products.

" The ZebOS Advanced Routing Suite has been designed to interoperate with network equipment from Cisco Systems, Juniper Networks, and other popular network equipment manufacturers. SNMP MIB support is provided to enable network management, billing, and provisioning applications. The ZebOS Advanced Routing Suite has been ported to a variety of platforms, including: VxWorks, Linux, Solaris, and BSD.

IP Infusion is also developing MPLS, IS-IS, virtual routing, and traffic engineering features and plans to add these features to its suite of products. IP Infusion is a member of the Network Processor Forum and is an active participant in the IETF standards organization.
