Abstract
A router is usable to transfer a packet from a first node belonging to one logical network to a second node belonging to another logical network. The router receives a first message for resource reservation from the second node, and stores a correspondence relationship between a first virtual connection available for receiving a packet of a specified flow from the first node and a second virtual connection available for transmitting the packet of the specified flow to the second node, when the first and second virtual connections exist. The router transmits a second message for resource reservation based on the first message to the first node, when the correspondence relationship can be stored. Alternatively, the router, after transmitting the second message to the first node irrespective of the correspondence relationship, transmits a cancellation message to the first node for canceling the second message depending upon whether the correspondence relationship can be stored.
