SearchStorage.com is a storage-specific portal with information about Fibre Channel switches and FC fabric technology. Eytan Modiano Slide 2 Packet switches • A packet switch consists of a routing engine (table look-up), a switch scheduler, and a switch fabric • The routing engine looks-up the packet address in a routing table and determines which output port to send the packet – Packet is tagged with port number – The switch uses the tag to send the packet to the proper output port Subscribe. A modular switch element (12) is programmable to operate in conjunction with varying numbers of other modular switch elements in a shared memory switch fabric (10). This paper examines switch fabrics with limited memory and their ability to exactly emulate an OQ switch.

Suppose that all packets are of the same length, n packets arrive at the same time to the n input ports, and all n packets want to be forwarded to different output ports. Assume the transmission time for an ACK is 0. Because a switched fabric network spreads network traffic across multiple physical links, it yields higher total throughput than broadcast networks, such as early Ethernet.
