METHOD FOR BALANCED RESOURCE SHARE IN THE OPTICAL TRANSMISSION NETWORK

摘要

The present invention relates to a method for sharing the resources distributed to the single failure protection path set by the optical transport network . ; how to share the resources in the distributed optical transmission network according to the present invention includes a first step of maintaining information on the number of the current connection in an optical transport network ; A second step of maintaining the list of the extracted link to the current working path ; Separated from the optical transport network for the entire network topology into a plurality of sub- domains, and a third step of extracting a sub- domain for the backup path ; A fourth step of extracting the backup path by applying a backup path setting algorithm of the sub- SRLG; And the application result , if successful in application , characterized in that it comprises a fifth step of verifying the validity of the link .
