Abstract
A network comprises a plurality of Access Routers arranged in one or more NetLMM domains. A domain comprises distributed routing information in the form of one or more Bloom filters or Bloom filter equivalents. In one embodiment, each Access Router may have an associated Local Bloom filter or Bloom filter equivalent that provides information as to which mobile nodes are currently behind the respective Access Router. Each Access Router sends its associated Local Bloom filter or Bloom filter equivalent to every other Access Router of the domain. An Access Router uses the Bloom filters or Bloom filter equivalents received from every other Access Router of the domain to determine to which Access Router to send a packet destined to a specified Mobile Node. Another embodiment uses partly-distributed routing information.
