Broadcom Corp. has rolled out its new StrataXGS III switch architecture featuring what it claims as the world's fastest, highest performing family of fully integrated Ethernet switch chips.

"With StrataXGS III, we are delivering an exciting new generation of switching silicon that enables reliable and secure communication of voice, video and data traffic on a single high-performance network," said Martin Lund, VP and GM of Broadcom's Enterprise Switch Line of Business. "Building on the success formula of the previous generations of StrataSwitch and StrataXGS, StrataXGS III features an impressive collection of unique technologies that will power the world's most advanced enterprise and carrier networks over the next several years."

The new StrataXGS III switches are touted to be the first to incorporate ubiquitous security, wire-speed IPv6 routing and wireless LAN support. Additionally, the StrataXGS III switch architecture features an advanced multi-layer 72Gbps full-duplex packet processing architecture.

Designed for feature-rich, high performance Gigabit Ethernet and 10GbE switch applications, the 500 series (the first StrataXGS III product family) includes five new chipsthe BCM56500, BCM56501, BCM56502, BCM56503 and BCM56504, each targeting different port and functionality requirements. The BCM56504 switch incorporates 24GbE ports and four 10GbE ports in a single-chip device, with each GbE port capable of operating at 10-/100-/1,000Mbps and each 10GbE port capable of operating in either 10GbE mode or stacking mode. Furthermore, this device is based on a 72Gbps packet processor that is capable of processing over 100 million packets per second.

Each member of the StrataXGS III family features the company's exclusive wire-speed Layer 2 to Layer 7 application-aware security technology that is designed to enforce secure policies based on a flexible variety of programmable rules. Also included is the Denial of Service attack prevention technology that provides continuity of service to users in case of an attack. And to complete the security features within all StrataXGS III devices, advanced cryptographic technology is integrated that meets the requirements defined by the U.S. Government's FIPS 140-2 standard.

Additionally, the StrataXGS III architecture fully integrates both IPv4 and IPv6 routing capabilities. According to Broadcom, this cost-effective implementation will enable the easy migration to IPv6 in corporate and service provider networks. Intelligent IP multicast technology is also featured within StrataXGS III switches, enabling service providers to offer new triple play capabilities (voice, video and data) and video broadcasting services.

And to reduce system development costs and accelerate time to market, the company provides an application programming interface (API) that maintains software compatibility with previous generations of Broadcom switches. In addition to providing a common API, Broadcom also provides reference designs for the StrataXGS III product series, including software, schematics, layout files and related documentation.

The 500 series of StrataXGS III Ethernet switches are currently sampling to Broadcom's early access customers.
