IP INFUSION ANNOUNCES ALLIANCE WITH AMCC FOR ADVANCED IP ROUTING SOLUTIONS FOR nP3400 AND FAMILY OF NETWORK PROCESSORS

February 11, 2002 San Jose, CA- IP Infusion announced today the integration of IP Infusion's ZebOSÔ Advanced Routing Suite, a leading edge IP routing software solution designed for networking, communications, and wireless developers, with AMCC's nPsoftT Development Environment and the nP Workbench-3400 design platform, creating one of the industry's highest performing router reference design solutions targeted at edge and core network equipment manufacturers. The two companies have also announced their intention to deliver a full IPv6 router reference design solution.

"IP Infusion has created an optimized version of its IPv4 routing suite that takes advantage of the data-plane software components provided by AMCC to build a fully functional router reference design on the nP3400 network processor. We have worked with AMCC to develop data-plane and control-plane routing software that operates at a high level of functionality and performance," said Nick Keating, President and CEO of IP Infusion. "Our initial integration work was done using VxWorks on a PowerPC environment. The combination of this real-time operating system and control plane processor, fully integrated and optimized with AMCC's nP family of network processors, provides equipment manufacturers with the quick turnaround time that they need to be competitive in today's market."

"As network processors are revolutionizing the way systems vendors build a variety of network equipment hardware, the availability of advanced and extensible networking software suites, such as IP Infusion's Advanced Routing Suite, pre-integrated and tested in conjunction with the latest advanced chipsets, can even further speed OEM time-to-market," said Jeff Cashen, vice president of AMCC's Switching and Network Processing Group.

The initial integration includes support for IP Infusion's ZebOS IPv4 routing suite, including OSPFv2, BGP-4, and RIP, using the VxWorks operating system on a PowerPC control processor. The AMCC nP Workbench-3400 platform with the nP3400 network processor and PowerPC act as the router reference design platform for this solution, supporting 24 10/100 Ethernet ports plus two Gigabit Ethernet ports. The ZebOS IPv4 suite interfaces with AMCC's IPv4 Application Services Library API and network processor-resident software. The ZebOS Advanced Routing Suite is based on the Network Services Module (NSM), which provides route table management, route conversion and distribution, as well as an industry standard command line interface. The protocol modules OSPFv2, BGP-4, and RIP run on top of the NSM. The NSM contains the control plane interface to the nP3400 network processor. Like all of AMCC's nP family of network processors, including the recently announced nP7510 10 Gbps network processor, the nP3400 is based on AMCC's patented nPcoreT Network-optimized Instruction Set Computing (NISC) technology, offering a flexible, fully programmable, yet powerful and highly efficient platform for building a wide variety of networking and communications equipment.

IP Infusion and AMCC are in the process of jointly developing IPv6 routing solutions by adding IPv6 data-plane and control-plane components to the nP Workbench-3400 router reference solution.
