Abstract
PTN network combines the advantages of SDH and traditional Ethernet. It can satisfy the smart grid for time synchronization, multicast, QOS and so on. This paper analyzes the time delay requirements of wide-area protection, the requirements of communication channel reconvery time delay with the same path and PTN protection technology. And we study the network protection technologies suit to the PTN networks carrying the wide-area protection. Finally, the time delay of Wrapping protection and 1∶1 LSP protection are verified by simulation testing. The simulation results are shown that Wrapping protection and 1∶1 LSP protection can meet the requirements of the wide-area relay protection in the PTN network.
