Abstract
With the projected growth in demand for bandwidth and telecommunications services, will come the reguirement for a multi-service backbone network of far greater efficiency, capacity and flexibility than the ISDN is able to satisfy. This class of network has been termed the Broadband ISDN, and the design of the switching node of such a network is the subject of much current research. This paper investigates one possible solution. The design and performance, for multi-service traffic, is presented of a fast packet switch based upon a non-buffered, multi-stage interconnection network. It is shown that for an implementation in current CMOS technology, operating at 50 MHz, switches with a total traffic capacity of up to 150 Gbit/sec may be constructed. Furthermore, if the reserved service traffic load is limited on each input port to a maximum of 80% of switch port saturation, then a maximum delay across the switch of the order of 100 μsecs may be guaranteed, for 99% of the reserved service traffic, regardless of the unreserved service traffic load.
