Mitel Semiconductor Announces DS313, a High-Performance Distributed Switch for Local Area Networks

Strategic Insights

— 2 min read

Mitel Semiconductor has announced the DS313, a single chip distributed switch that supports Layer 2, 3, and 4 packet forwarding and filtering in Local Area Networks (LANs). This device, designed by Vertex Networks, Inc., operates at full wire-speed and includes advanced features such as enhanced Quality of Service (QoS), Layer 3 routing, and protocol filtering. The DS313 is the latest member of the XF2080 family, supporting advanced network management software and QoS standards for packet prioritization.

The DS313 is highly integrated, reducing the overall system chip count and glue logic. Its robust QoS capability, low latency, and high frame-forwarding rate make it an ideal choice for time-critical data. The device is also designed to support up to 22K IP subnets per chip or 64K MAC addresses per chip and per system. According to IDC, LAN switching represents a high-growth opportunity in the enterprise marketplace, with Layer 3 switches expected to account for most of the revenue in this segment from 1999 to 2003.
