  • Local area network interconnection system implementing a routing protocol of the "source routing" type and interconnection equipment intended to be used in such a system
    Patent number: 5848242
    Abstract: Interconnection of local area networks, which use a protocol of the "Source Routing" type, through a wide area network involves pieces of interconnection equipment each having a configuration memory which avoids systematic broadcast of discovery frames on the wide area network. Machine learning by these pieces of interconnection equipment stores in respective configuration memories the address of the interconnection equipment through which a local area network containing a destination station is situated. For a given size of routing information field, the maximum number of interconnected networks is doubled.
