Abstract

The system design and architectural considerations for a large, high-performance IP packet router that uses a nonblocking optical switching fabric are presented. The objective of the router is to provide fully network-compatible routing of IP, multiprotocol label switching (MPLS), and Ethernet packets in a router with a very large number of high speed ports while maintaining the low-delay, low-jitter, low-packet-loss, and line-rate throughput characteristics of today’s small port-count routers over a large scale. Such a large router is useful for the core of a packetized transport network capable of supporting various classes of real-time and best-effort service in a reliable and efficient manner.
