Popis: This paper proposes a new asynchronous transfer mode (ATM) switch architecture called a “barrel switch.” The barrel switch is constructed from n/2 × n identical element switches which are placed out around a cylinder and connected to each other. The features of this proposed switch are as follows. 1. This switch has an architecture suitable for high-speed (2.4 Gbps and more) cell switching. 2. It is a multistage self-routing and nonblocking switch. 3. Copy connections can be realized with this switch. 4. The building-block method is applicable to switch implementation, which ensures a full scalability. Cell loss rate and delay characteristics of this switch also are discussed using computer simulation results. Simulation results under random traffic prove that a 64 × 64 barrel switch has adequate cell loss rate and mean delay characteristics to an actual ATM switching system.
