Silicon Access Networks Announces iFlow Development System

Hardware Development Platform Provides Proving Ground for iFlow™ Chipset Designs

SAN JOSE, Calif. - October 22, 2002 - Silicon Access Networks, an industry leader in IC data path packet processing solutions, today announced availability of the iFlow™ Development System (iDS), a complete hardware development platform for performance evaluation and networking applications development based on the 20Gbps iFlow Data Path Processing platform. The platform includes the iFlow Packet Processor (iPP), iFlow Address Processor (iAP), iFlow Classifier (iCL) and iFlow Accountant (iAC). The iFlow solution enables a new level of services and reliability in Metropolitan, Wide Area and Enterprise network routers and switches.

With the iDS, Silicon Access Networks becomes the first company of its kind to deliver working silicon, a complete software toolset and an integrated development system.

"The iDS represents a significant architectural milestone for Metropolitan/Enterprise Gigabit Ethernet and Packet-over-SONET applications," said Perry Constantine, president and CEO of Silicon Access Networks. " "Being the first company to deliver working silicon in an integrated design system has established Silicon Access as the industry leader in providing the most innovative and reliable solutions for network routers and switches."

The iDS is a hardware platform consisting of a physical interface module, a data path processing module, a traffic management/loopback module and a control plane module. It is based on a modular design, which allows for removable optical interfaces as well as traffic management and fabric interface support. The individual modules connect over standard interfaces: SPI 4.2 for packet data and PCI for control plane data.

The iDS works in conjunction with the iFlow Reference Software (iRS) and iFlow Programmer's Environment (iPE) which provides a consistent interface for both system emulation and hardware development. It can be used to jumpstart hardware and software development programs, and ships complete with all software source code, hardware schematics and Gerber files.

The iDS will be available in Q4 2002 at a cost of $60,000. It is available in multiple system configurations, to meet the cost and application requirements of a variety of customers.
