Mitel Packet Switch Chip Speeds Up IP Routing

[Ottawa, CANADA] Mitel Semiconductor, a division of Mitel Corporation, has rolled out its DS313, a single chip distributed switch for Layer two, three, and four packet LAN forwarding and filtering.

The device, which includes 12 Fast Ethernet ports and one gigabit port, operates at full wire-speed and includes a full suite of advanced features such as enhanced Quality of Service (QoS), Layer three routing, IP Multicast, protocol filtering, port mirroring, port trunking, buffer management, and stacking.

The DS313 was designed by Vertex Networks, which was acquired by Mitel in July 2000 to beef up Mitels switching and routing expertise.

The chip's robust QoS capability, low latency, and high frame-forwarding rate make it a strong choice for time critical data.

The need for high-availability networks is a key driver of LAN switching growth, and Layer three switches are expected to account for most of the revenue in this segment from 1999 to 2003.

Layer three shipments are forecasted to increase from nearly five million ports and $3 billion in revenue in 1999 to more than 59 million ports and $11.4 billion in revenue in 2003.

"While most of our competitors only route 16 or 32 longest prefix IP addresses, the DS313 is capable of routing over 6,000," said Tim Thompson, director of marketing at Mitel Semiconductor.

"The technologies integrated into the DS313, when combined with Mitel's existing products, provide a formidable solution for numerous LAN and WAN specific applications, including remote access concentrators and VoIP gateways."
