The asynchronous transfer mode (ATM) is considered to be the most appropriate for broadband ISDNs because of its bandwidth flexibility and time transparency. This paper proposes an architecture for ATM switching, based on a self-routing switching principle. It is constructed by connecting self-routing switching modules in a three-stage link configuration. We call this architecture multistage self-routing (MSSR). The cell-loss probability and delay have been evaluated.The results show that even when voice signals occupy 70% of the transmission capacity and burst data occupy 20%, the average delay per node is less than 60ps and the cell-loss probability is less than . This shows that this system has a larger traffic capacity than existing circuit switches, which are designed for an average loading of 70 to 80%.

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.

This paper proposes a switching system for the broadband integrated service digital network (B‐ISDN). The proposed system uses self‐routing and a multistage switching configuration. Asynchronously arriving information blocks are switched one by one at high speed. This configuration suppresses cell collision that can occur in asynchronous transmission. This paper describes the system configuration, a technique for designing the system's basic parameters, and system effectiveness.

We propose a traffic control scheme for asynchronous transfer mode (ATM) switching systems, clarifying requirements for traffic control derived from the ATM network characteristics and demonstrating basic control concepts. The proposed scheme accepts calls based on the available bandwidth and buffer use rate, making it possible to integrate the network without classification by service type.
