Cortina launches 40-Gbit/sec Ethernet MAC aggregator IC

Jan. 23, 2007
JANUARY 23, 2007 -- The CS3477 enables a leap in 10-GbE port density for switches and routers with four Native 10G serial XFP ports and Interlaken support, claims Cortina Systems.

JANUARY 23, 2007 -- Cortina Systems (search for Cortina Systems) has announced what it claims is the market's highest density 10-Gbit/sec Ethernet MAC Aggregator IC, CS3477, which doubles the bandwidth over previous components to meet the new density requirements of leading communication system providers.

CS3477 integrates direct serial connectivity to XFP optical modules to eliminate power draw, cost, and size from the separate serializer chips in use today, say company representatives. With both 10-Gigabit Ethernet (10-GbE) LAN and WAN PHY integration, it addresses enterprise and metro needs. The four 10-GbE MACs include Layer 5 classification capabilities to identify and protect critical traffic flows. They provide a complete 10-GbE offering for both wire speed blades optimized for performance as well as oversubscribed blades optimized for port density and cost, says Cortina.

This level of performance is enabled by the use of Interlaken (search for Interlaken) uplink ports, an open industry standard created by Cortina and Cisco for inter-component connectivity.

"Cortina partnered with leading networking companies to create CS3477, which delivers the highest density, lowest power aggregation for both wire speed and over subscribed systems," reports Zino Chair, vice president of marketing at Cortina. "With its native XFP connectivity eliminating the need for surrounding components, the CS3477 enables a generation step in high density line cards."

With its advanced classification and IPv6 MPLS support, multiple queues per port, deep buffer options, and advanced scheduler, CS3477 delivers intelligent oversubscription capabilities for packet priority control. It also incorporates subscriber functionality like per-VLAN policing, statistics, tagging, and classification to assist in the delivery of metro Ethernet services. The Interlaken interface delivers up to 40-Gbit/sec uplink capacity for wire speed, 2:1 or 4:1 oversubscription ratio.

CS3477 is currently sampling to multiple customers.
