REPAIR SERVERS IN UNRELIABLE PACKET-SWITCHED COMPUTER NETWORK WITH MULTICAST TRAFFIC

摘要

The paper discusses localization of repair servers at the nodes of an unreliable packet-switched computer communication network, where the latter supports multicast traffic. It is assumed that the multicast traffic is carried in unreliable network, i.e., via unreliable communication channels characterized by failure probabilities. The problem of repair servers localization in a network with unreliable channels and multicast traffic may be considered as a problem of multicast efficiency in terms of network resource consumption and average packets delay introduced by the network. For the purpose of the paper it is assumed that the quality of multicast network in terms of network resource utilization is measured by average delay of transferred packets. The aim of repair servers localization at various nodes of the network considered is to decrease average packet delay delivered by the network.
