Routing information generating apparatus, routing information generating method and routing information generating program

摘要

Network connecting sections of an own station deliver routing information notified from a relay section on the same base to network connecting sections of other stations of own networks. If new routing information is present in routing information received from the network connecting sections of the other stations, the network connecting sections of the own station notify the relay section on the same base of the routing information. The relay section updates, based on the routing information notified from the network connecting sections on the same base, routing information held by the relay section.

主权项

1. A routing information generating apparatus comprising:
a relay section; and at least one network connecting section connected to a respective network from a plurality of networks, wherein each of the at least one network connecting section comprises:
a routing-information delivering section configured to set routing information held by the network connecting section based on routing information received from a relay section and configured to deliver the routing information held by the network connecting section to stations connected to an own network;a routing-information comparing section configured to compare the routing information delivered from another station of the own network and the routing information held by the network connecting section;a routing-information updating section configured to update, based on a result of the comparison by the routing-information comparing section, the routing information held by the network connecting station; anda routing-information notifying section configured to notify the relay section on a same base of the routing information held by the network connecting section, wherein the relay section updates, based on the routing information notified from the network connecting section on the same base, routing information held by the relay section, and notifies the network connecting section on the same base of the updated routing information held by the relay section, and wherein the network connecting section updates, based on the updated routing information notified from the relay section, the routing information held by the network connecting section, delivers the updated routing information to the network connecting section of the another station, and repeats the notifying the relay section on the same base of the routing information until no new routing information remains in routing information received from the another station.
