Abstract: |
The present invention relates to a method for enhancing survivability of automatic switching optical network (ASON). Said method is characterized by that said invention utilizes the downstream node of damaged chain link to coordinate optical network resource distribution of damaged channel, solve the influence of optical network resource collision to network survivability in the course of chain link failure restoration and raise restoration successful rate. Said invention adopts a staged parallel restoration process so as to reduce connection creating time. |
