Abstract
A new self-routing multicast network that can realize arbitrary multicast (or one-to-many) communication without any blocking. Based on the binary radix sorting, all functional components of the network are recursively constructed reverse banyan networks using a self-routing procedure that provides for pipeline distribution of switch settings. The design allows a potential to greatly reduce the network cost by reusing part of the network. The new multicast network has O(n log.sup.2 n) cost (logic gates), O(log.sup.2 n) gate delay, and O(log.sup.2 n) set-up time, where the unit of time is a gate delay. Further, with feedback part of the network can be reused and the network cost is reduced to O(n log n).
