A survey of multi-connected loop topologies for local computer networks

Abstract

Abstract Loop network architectures are an attractive topology for local computer networks because they require simple interfaces and control. Single loop networks tend to become unreliable when the number of nodes in the network becomes large. Multiconnected loop topologies have been proposed for improved reliability and performance. There are several double loop networks based on forward loop backward hop topology, with a loop in the forward direction connecting all the neighboring nodes, and a backward loop connecting nodes that are separated by a distance h. This paper presents a systematic study of single and double loop networks and also discusses various other loop networks with higher connectivities.
