A Dynamic, Cut-Through Communications Protocol with Multicast
Gregory T. Byrd, Russell Nakano, Bruce Delagi · 1987
This paper describes a protocol to support point-to-point vinterprocessor communications with multicast. Dynamic, cut-through routing with local flow control is used to provide a high-throughput, low-latency communications path between processors. In addition, multicast transmissions are available, in which copies of a packet are sent to multiple destinations using common resources as much as possible. special packet terminators and selective buffering are introduced to avoid deadlock during multicasts. A simulated implementation of the protocol is also described.
