This paper presents a new logical topology GIADM-net, a generalised IADM network for enhancing the reliability of optical networks using wavelength division multiplexing. The presence of multiple number of paths of same distance between any two nodes in exchange of reasonable number of hops in the network, ensures a higher degree of reliability compared to other existing topologies in case of link failure, as well as in balancing link loading in the network so as to maximise the network throughput. This GIADM-net, connects any arbitrary no. of nodes in a regular graph as opposed to the cases in De Bruijn graph and shufflenet. The average hopping distance between two nodes, using this topology is smaller, compared to that in GEM net, shufflenet and De Bruijn Graph, at the cost of marginal increase in diameter. © Springer-Verlag Berlin Heidelberg 2000.
