Implementation and performance analysis of congestion-tolerant isochronous communication in ATM networks using diversified routing
Abstract
Packet loss resulting from transient traffic congestion or hardware component failures has been a potential problem for existing ATM networks that support isochronous traffic. Packet retransmission is usually less effective in an isochronous environment due to its timing requirements. The implementation and performance of a space diversified approach for establishing isochronous interconnection is studied in this paper. In this scheme, a packet is either replicated or split into smaller packets with parity packets and sent through physically disjoint connections. By providing either partial or full redundant connections through a network, the probability of transmitting a packet that meets the jitter requirement can be increased for the same jitter bound, or a more stringent jitter bound can be imposed for the same packet loss probability.
