Next Generation Networks 2000

NGN2000 Demonstration Showcases Industry's First Working

High-Speed Router Reference Design Based On Open-Source Software and

Off-the-shelf Network Processing Chipsets

MMC Networks, a wholly owned subsidiary of Applied Micro Circuits Corp.

(Nasdaq:AMCC) and MontaVista Software, Inc. today announced a joint public demonstration of the industry's first high-speed Internet Protocol (IP) router reference design based completely on off-the-shelf network processing hardware and open-source Linux-based software. This joint reference design signals a significant advance for the networking industry, allowing a completely new generation of networking and communications equipment vendors to bring products to market more rapidly than ever.

MMC Networks is the market leader in network processors for rapid development of multi-gigabit networking and communications products, while MontaVista Software is the leading embedded Linux provider. MMC and MontaVista have combined MontaVista's Hard Hat Linux for real-time applications with MMC's complete network processing platforms (network processors, switch fabrics, and traffic management engines), the MMC nPsoft(TM) Development Environment -- including base system software, IP routing application reference library and developer API -- and additional open-source application code.

This marriage of MMC Networks' high-performance, deterministic hardware and software with MontaVista's cost effective, functionality-rich Linux platform forms the potential base for a variety of Layer 3-7 service provider WAN and enterprise LAN devices. Network equipment vendors can, in turn, focus precious software resources on adding their own unique value to products ranging from broadband and optical access to IP subscriber management, Web switching and more.

"This innovation enables the development of high-speed switching and routing systems based completely on off-the-shelf technology," stated Jim Ready, president and CEO of MontaVista Software. "By combining MontaVista Software's expertise in Linux and open-source software for real-time embedded applications with MMC Networks' market-leading network processors, the networking equipment vendors can enjoy a dramatic time-to-market acceleration."

"The technological advancement demonstrated today allows network equipment vendors to further concentrate on development of their own differentiating system features," stated Doug Spreng, president of MMC Networks. "Rather than spending time and resources on ASIC design and base system software development, network equipment vendors can put those efforts into creating system differentiation and ultimately garnering a higher stake in their respective markets."

Integration Time Reduced

Even with off-the-shelf hardware, many network equipment vendors want to get as much of a head start on software as possible. The engineering community is certainly familiar with the time-to-market and cost benefits of open-source software for PC-based systems -- including both the Linux operating system and open-source networking application code written for and freely available to run on Linux - but with high-speed switches and routers, the hardware and embedded software environment is considerably more sophisticated than a desktop PC.

Typically, high-speed switch/router developers must first create their own application (e.g., IP routing) code for both their central management processor (CPU) and their fast-forwarding network processors (NPUs). Then they have to integrate management processor, network processor, switch fabric, and traffic management hardware with both their own software and a real-time operating system (RTOS).

As today's demonstration illustrates, MMC and MontaVista have done both the custom development and open-source integration work to deliver a complete hardware and software reference design for an off-the-shelf high-speed IP router.

MMC and MontaVista Reference Design Demo

MMC and MontaVista are jointly demonstrating this reference design here at the Next Generation Networks 2000 conference. This demonstration marks the first working high-speed router reference design based purely on open-source software and off-the-shelf networking processor chipsets. The reference design incorporates:

-- MMC's chassis-based development system hardware, with nP7000 family line
cards connected to an nPX5000 family switch fabric and traffic management
engine

-- MontaVista's enhanced Hard Hat Linux RTOS on the management CPU

-- MMC's nPsoft(TM) Services framework software and nPsoft IPv4 routing
application reference library on both the NPUs and management CPU

-- Open-source application-layer routing information protocol software,
integrated with Linux RTOS and MMC's nPsoft API
