Node apparatus, route control method, route computation system, and route computation apparatus |
摘要 |
A node apparatus wherein when a topology change occurs on a network used for packet transfer between node apparatuses, the node apparatus performs dynamic route control for establishing a new normal route. The node apparatus has a device that receives, from another node apparatus, a route control message which includes information required for route determination; a device that computes a route on the network based on the received route control message; a device that sends another node apparatus a route control message which includes information required for said another node apparatus to determine a route on the network; a device wherein when receiving the route control message, this device computes an operation start time for route control operation by the route computation and the message sending, based on a distance between a topology change part and said node apparatus of oneself; and a device that controls the execution of the route control operation based on the computed operation start time.
