abstract
1999 IEEE. We present methods to provide fault-Tolerant real-Time communication over ATM networks. Specifically, we are concerned with messages that have to be delivered by their deadlines even in the presence of faults. Connection-oriented communications service is well-suited for mission critical applications that demand delay guarantees. A critical part of connection oriented communication is the design of a connection admission control algorithm. We develop innovative fault tolerant real-Time connection admission control algorithms that use an integrated spatial and temporal redundancy scheme and provide algorithms that determine the appropriate redundancy parameters. To aid delay analysis, we first develop a generic traffic model to describe the traffic of individual connections in the network. We then develop an analytical method to derive the end-To-end delay bounds taking into account the impact of faults.
