<p>A method of realizing protecting switching on packet double-ring network, the method makes two sides of the same node of the ring network run status mechanism respectively, uses "side" not "node" as basic running unit, and expands therein status of the nodes from three kinds to eight kinds, two sides of each node disposes various status respectively, comprises steps: a, completes initialization of one side of the node on double-ring, sets the physical status and logical status of the side; b, according to the status of the side, the side sends request punctually to neighboring node and neighboring side, at the same time, the side receives the request coming from local side neighboring side and neighboring node; c, the side disposes the received new request ,and according to the disposed result, completes the switching of logical status and physical status, and return to step: b. Using the method of present invention, multipoint, simple point and multi-failure intelligent protecting switching can be achieved on packet double-ring network simply rapidly and expediently.</p> |
