ABSTRACT:
A network switching control met:hod controls switching from an active route to a protection route when a failure has occurred in any of nodes of a communications network or any of transmission paths connecting the nodes so that the communications network is formed. Route switching is performed quickly and efficiently. The protection route is formed via n nodes among the plurality of nodes where n is an integer larger than or equal to 2. The method includes the step of generating, at a first node which is one of the n nodes, a switching control instruction which includes information for requesting each of n-1 nodes other than the first node to form the protection route. The switching control instruction includes address information concerning the nodes forming the protection route. The method includes the step of sending the switching control instruction, without including other management information at that time, from the first node to a second node which is one of the n-1 nodes adjacent to the first node. The method includes the step of generating, at each ith node where i=2, 3, . . . , n-1, where n is greater than or equal to 4, a switching control instruction to be transferred to a first adjacent node in the protection route. The switching control instruction is transferred in response to receipt of information indicating an address of the ith node included in a switching control instruction transferred from a second adjacent node in the protection route. The method includes the step of transferring the switching control instruction generated by the above step to the first adjacent node from the ith node.
