1. In a computer network which includes a plurality of nodes, each node having interconnections between neighboring nodes, the plurality of nodes having at least one server node, each server node having one or more associated resources and a URT, each URT capable of containing entries, each entry having a resource identifier, unavailability period and a search threshold, a method for reducing network resource location traffic comprising the steps of:

  • checking the URT of a first server node for an entry having a resource identifier that contains a representation of a target resource, in response to a request for the target resource from a source resource associated with the first server node;

    determining that the target resource is unavailable if the unavailability period of the found entry has not expired and the search threshold of the found entry has not been exceeded, if an entry is found in the URT;

    informing the source resource that the target resource is unavailable and updating the search threshold of the found entry in the URT, if the target resource is determined to be unavailable;

    initiating a network search for the target resource, if no entry was found in the URT or if the target resource was not determined to be unavailable; and

    updating the URT based on the results of the network search, if the network search for the target resource is unable to locate the target resource and deletes any entry for the target resource if the target resource is located.
