Te r a S t r e a m ® Chip Set (VSC871 & VSC881) 160 Gb/s Intelligent Switch Fabric
GENERAL DESCRIPTION: T h e TeraStream ® product is a third generation Intelligent Switch Fabric using Vitesse's proven high-speed serial link technology. This product consists of the VSC871 Queuing Engine and the VSC881 Packet Exchange MatrixTM, and supports aggregate user bandwidths of up to 160Gb/s with port speeds reaching 10Gb/s. High Integration Reduces Overall Cost Manufactured on a 0.18µm CMOS process, the TeraStream chip set integrates advanced queuing and scheduling, a synchronous serial crossbar, and multiple SerDes in a dualchip fabric architecture. The TeraStream fabric is a lowpower solution with the capability of powering-down unused serial links. Transmission between each line card and one or more switch cards is conducted entirely in-band via the integrated SerDes. This results in a high-performance, costeffective switch fabric with a low overall chip count to minimize power, design complexity and board space requirements. High Performance and Scalability The TeraStream Packet Exchange Matrix supports 32 highspeed, self-clocking serial links, each operating at a maximum user data rate of 2.5Gb/s. Multiple chips can be combined to increase the overall port bandwidths to support dense system configurations such as 64x64 OC-48 and 16x16 OC-192. In addition, the TeraStream switch fabric protects the user's line card investment with a seamless upgrade option to future members of the TeraStream family of switch fabrics. Efficient Bandwidth Utilization The TeraStream solution is a self-routing switch fabric with logical backplane link rates at twice the user port bandwidths (2X speed-up), Virtual Output Queuing (VOQ), and sophisticated Quality of Service (QoS) mechanisms to ensure non-blocking performance. The fabric supports both unicast and multicast traffic, each with 16 discrete classes of traffic partitioned between strict priority and weighted bandwidth allocation. Multicast traffic is replicated in the TeraStream Packet Exchange Matrix to optimize ingress link bandwidth utilization. High Availability The TeraStream switch fabric offers several features designed to simplify on-site replacement or upgrades. The 1:1 redundant switch core protection scheme supports both automatic hardware switchover for link failure conditions as well as software-controlled hitless switchover for field maintenance. The fabric employs fail-safe, hot-swappable buffers that permit line cards to be removed or inserted into a live backplane without damage. To assist in error detection, each Queuing Engine's primary and integrated redundant serial links have independent self-synchronizing link circuitry and link health monitoring. Proven Technology Minimizes Risk The TeraStream Switch Fabric uses proven high-speed serial link technology to communicate across the backplane, leveraging Vitesse's experience in real-world, high-speed semiconductor transceiver technology. TeraStream can interface with Vitesse's or any CSIX-compatible, third party traffic manager or network processor. Application notes, reference system design documentation, and experienced support teams are available to accelerate development times and ensure first-pass system success.
