A METHOD FOR IMPLEMENTING MASTER AND BACKUP TRANSMISSION PATH

摘要

A method for implementing master and backup transmission path comprises steps: set backup LSPs for each physical transmission link in Data Communication Network (DCN); and when the physical transmission link fails, transmit the packets that need to be transmitted on the physical transmission link to the backup LSP to transfer. The present invention can enhance the packet transmission reliability of DCN and reduce the maintenance workload and complexity of the master and backup transmission path.
