摘要
The present invention relates to protection and restoration method for MPXS in optical mesh networks, particularly to protection and restoration method which can find and restore fast failures by configuring routing table with working label and protection label when failures occur at links or nodes. ;According to the present invention, by configuring a routing table consisted of working label and protection label and by setting an optical path as working path and protection path, data is transferred through the working path, and when a failure occurs in a optical path, data is transferred through a protection path by using a preliminarily configured protection label and by switching to. ;According to the present invention, by configuring routing table with working label and protection label, failures can be restored fast when failures occur at links or nodes, and whole network resources can be applicable.
