Method for protecting and restoring link using optical label merging and dynamic resource sharing with network load |
摘要 |
Disclosed herein is a method for protecting and restoring a link in an OBS network. The method includes a step of transmitting/receiving a liveness-confirming message for confirming liveness of the link between an up-node and a down-node respectively connected to both ends of the link at a predetermined message transmission period, to judge whether a fault is generated on the link, a step in which the up-node and down-node respectively update link information when it is judged that the link fault is not generated, and a step of restoring the link having the fault using predetermined restoration channel information based on an offered load measured when the link is in a normal state when it is judged that the link fault is generated. Accordingly, a link having a problem can be effectively protected and restored in the OBS network.
