Switching system based on the switching of service grade, include multiple RPR equipment which compose one RPR ring, service classification processing unit, upper switching unit and dispatching unit; RPR frame processing unit dispose the RPR frame which come from loop circuit; service classification processing unit done the service grade classification for the Ethernet service which come from local port; upper switching unit select output ring in shortest route principle; dispatching unit 9 dispatch the non-local service from the RPR loop circuit and the classified service, and output from the loop. The present invention realize bridging of Ethernet service and RPR loop circuit by the classification of service and unified dispatching for all the service, provide a kind of switching system and switching method aim at RPR technique, in addition, the present invention can fusion many kind of service classification technique to classified service frame, make different dispose to different grade of service, thereby it take many kind of strategies for providing many kinds of service and price. |
