Abstract

The architecture of the MOBAS (Multicast Output Buffered ATM Switch) has a regular and uniform structure and, thus, has the advantage of easy expansion, high integration density for VLSI implementation, relaxed synchronization for data and clock signals and building the center switch fabric with single type of chip. Modified MOBAS has a similar modular distributed structure to MOBAS, and has fewer switch elements than the MOBAS. The reduction of a switch size and the fault tolerance are important issues in designing an ATM switch for reliable satellite communications. In this paper, we analyze the fault-tolerance characteristics and propose the detection and location schemes of the Modified MOBAS. And, we propose a new ATM switch architecture with fault tolerant characteristics by slightly changing Modified MOBAS. The proposed switch has an easy fault reconfiguration scheme with graceful performance degradation like MOBAS and employs fewer switch elements than the MOBAS.
