Abstract

Broadband integrated services digital networks (BISDN) are designed to offer a variety of services with bit rates ranging from several kb/s (e.g. teleactions) to hundreds of Mb/s (e.g. HDTV), and in some cases approaching Gb/s (e.g. in interconnections of high-speed LANs). A multiplicity of rates and the burstiness of traffic sources lead naturally to systems based on the fast packet switching (or asynchronous transfer mode) concept. The requirements of data buffering and high-speed processing of packet headers have resulted in a plethora of proposals for ATM switching nodes and an equal number of ways for evaluating them. In particular, the class of non-blocking architectures of ATM switches has received the most attention from the research community. This paper reviews this class of architecture with emphasis on contention resolution methods and communication traffic performance. The contention resolution methods are divided into four categories: input buffering, output buffering, shared buffering, and hybrid buffering. The communication traffic characteristics are divided into two categories: uniform traffic and bursty traffic.
