Gigabit networking research at Bellcore

Abstract
A communication architecture appropriate for gigabit networks, the multimedia end-to-end communication architecture (MECA), is described. MECA provides multimedia applications with the service they require in a single communication system. MECA encompasses the network, host-network interface, and associated protocols. The architectural characteristics of MECA are compared with those of existing communication systems and the TP++ transport protocol used by MECA is compared to existing transport protocols. Three host-network interfaces built for AURORA, a five-gigabit testbed network that includes an experimental asynchronous transfer mode (ATM) network running over a synchronous optical network (SONET), are described. The Sunshine ATM switch that supports MECA using a scalable Batcher-Banyan switching fabric and highly programmable port controllers is discussed.
