Experimental broadband ATM switching system

Abstract

Asynchronous transfer mode (ATM) switching is considered the most appropriate for broadband ISDN because of its bandwidth flexibility and time transparency. This paper describes an ATM switching architecture based on a self-routing principle and an experimental system. It is constructed by connecting self-routing modules in a three-stage link configuration. We call this architecture multi-stage selfrouting (MSSR). We confirmed that MSSR switching can deal with various media such as voice, data and video.

A survey of modern high-performance switching techniques

“…13. It has been proposed, e.g., in [59], in the Bus Matrix Switch described in [60], or in the experimental broadband ATM switching system described in [61]. The architecture is motivated by the fact that the concept provides almost ideal performance, at least as long as the queues are dimensioned Jong enough.…”

“…The architecture is motivated by the fact that the concept provides almost ideal performance, at least as long as the queues are dimensioned Jong enough. On the other side, because of the square growth, it is a very expensive approach for large matrices and can only be a good solution either for small switches or as basic architecture for the building blocks of modular multistage arrangements, as proposed in [60] and [61].…”

Impact of scheduling algorithms on performance of crosspoint-queued switch

“…This implementation is called the crosspoint queued (CQ) switch. Switches with small buffers in crosspoints as switching elements of banyan switches have been evaluated in the late 1980s, but that evaluation was mostly limited to uniform traffic and short buffers [15,16]. The technology limitations made this approach impractical for implementation at that time.…”
