Tau Delivers Switch Fabric

SAN JOSE, Calif. -- Tau Networks, a new company delivering switch fabric chipsets for multiple communications and computing markets, today announced sample availability of its T64 switch fabric chipset, comprising the TL2410 Line Interface and TX6410 Crossbar/Scheduler ICs. Linearly scalable from 2.5 Gbps to 640 Gbps of true full-duplex bandwidth, the two-chip T64 delivers high-integration, protocol-independent switching with world-class Quality of Service/Class of Service support and high availability, at the lowest cost in the industry. From highly scalable enterprise LAN and SAN switches to multi-service MAN and WAN platforms, system OEMs can now achieve more revenue-generating ports, in fewer chips at a lower cost. T64 employs patent-pending queue management to provide up to 64 ports in a fully configured fabric, each with 64 dynamic rate flow-controllable sub-ports and 16 flexible classes of service. An industry first for switch fabrics, the TL2410 provides a 20 Gbps implementation of the Network Processing Forum Streaming Interface (NPSI). T64 supports guaranteed bandwidth and latency for applications such as digitized voice or VoIP at STS-1 granularity. The highly integrated chipset requires no external components and provides on-chip 3.125 GBd serdes channels for efficient high-speed system interconnects. The T64 provides extensive redundancy capabilities, including 1:1 hitless dual-path as well as datacom-style (N+M) and graceful degradation (N-1) capability. Failover to backup paths is hardware-based and ultra-fast. The T64 supports seamless capacity increases or decreases, with no interruption in fabric operation, allowing end users to change redundancy schemes and fabric overspeed in real time, in the field, without bringing down the fabric or affecting traffic on other ports. True "pay as you grow" scalability and protocol independence allow OEMs to deploy common fabric designs across multiple product families, reducing development and inventory costs. Tau Networks Inc.
