  • Directory services caching for network peer to peer service locator
    Patent number: 6680942
    Abstract: A new directory service is established for a peer router receiving a data packet from an end station on a local area network connected to a port of the peer router, the peer router hereinafter being referred to as the source router. The data packet is addressed to a destination address. The source router determines that the data packet is to be encapsulated as an encapsulated packet, and the encapsulated packet routed by a peer-to-peer protocol to a destination router. The destination router then transmits the packet onto a local area network to the destination address. The source router locates the proper peer destination router by use of a database. The database is maintained on a server, where the database has entries for destination address, and an entry for a particular destination address gives the address of a peer router capable of routing a packet to that particular destination address.
