Abstract:
1. A method of updating a routing table of an information transfer system, the system including a plurality of nodes, each of the nodes being associated with any one of a plurality of partitions, the nodes communicating with another node based on information set in the routing table, the method comprising: receiving, from an issue-source node, a write packet that includes update data for updating the routing table; determining whether first partition information indicating a partition with which the issue-source node is associated is included in the received write packet or in the routing table; determining not to permit updating of the routing table; when the first partition information is included in neither the received write packet nor the routing table and when either of port information or second partition information included in the update data has been stored in the routing table; determining to permit updating of the routing table when the first partition information is included in neither the received write packet nor the routing table, when neither the port information included in the update data nor the second partition information has been stored in the routing table, and when the issue-source node matches node information included in a corresponding entry in the routing table; determining not to permit updating of the routing table when the first partition information is included in either the received write packet or the routing table, and when the first partition information matches the second partition information, when the port information included in the update data has been stored in the routing table, and when the second partition information is different from partition information included in a corresponding entry in the routing table; and updating an entry of the routing table based on the update data when it is determined to permit updating the routing table.
