Abstract
Managing end stations locations in a bridged network includes providing a smart bridge, and performing communications operations using a network flood active port connections table, a network flood reaching table, a best path forwarding table and a best path sourcing table. An end station locations revision manages a host location (HLOC) table. End stations locations revision is invoked upon detection of changes in any end station location. The end stations locations revision exchanges location revision grandparent (LRG), a location revision child (LRC) table and a location revision wavefront distribution protocol. The locations revision passes the location revision request from the smart bridge over a topology of the bridged network. A location revision wavefront starts at the root and, spreads a location revision request for revising the HLOC of the other smart bridges. The wavefront spreads by wavefront protocol.
