… the present invention relates to a high speed transmission sytem in a large packet
switching network and, more particularly, to an apparatus and method for speeding up the
path selection between a source and a destination node by means of an automatic
decomposition of the network topology into a backbone and a … the object of the invention
is to perform an automatic decomposition of the network into a backbone and subareas to
speed up the path selection without degrading the optimization criterion of the routing …
