Document Type and Number:
Japanese Patent JP4372104
Kind Code:
A protection path reservation method which reserves protection paths to avoid a node failure for each transmission path on a network formed of a plurality of nodes, comprising assuming the nodes as an imaginary failure node in turn in a condition in which the node failure is not present in the network, and selecting N neighbor nodes connected to the imaginary failure node through N links, wherein the imaginary failure nodes sequentially transmit protection path reservation request messages to neighbor nodes, and the nodes which have received the protection path reservation request messages sequentially, one by one, reserve N-1 protection paths starting from the nodes.
