Attorney, Agent or FirmInternational ClassH04L 012/28Foreign Application Priority Data1995-07-19 JPAbstractA link state routing device reduces amount of link state information exchanged in a network irrespective of number of links connecting between adjacent switches. Hello protocol portion detects adjacent switches in the network, to which respective of links are connected. A link abstracted portion obtains an abstracted link by virtually aggregating a plurality of links connected to the same switch, and generates a link state with respect to abstracted link with uniting link state information of a plurality of links. The link state update protocol portion has link topology information synchronized in the network by distributing the abstracted link state information with flooding mechanism. Since the abstracted link represents a plurality of links, information amount to be distributed can be reduced.Other References
