摘要:
A communications network comprises a plurality of linked nodes between a source and a destination. At each node the state of the network and its links are measured and stored with advertisements from other links. The node also performs a routing algorithm to define the instantaneously best path to the destination for the current network state. The routing algorithm responds to a plurality of metrics, including costs of links, and may use fuzzy logic which derives a fuzzy cost for candidate paths to derive a least fuzzy cost path to be followed. Traffic is shared between a path which is determined to be the best, at the current point in time, and a path which has previously been determined as the best path. The network can be a network which carries mobile cellular traffic.
