<p>The present invention relates to a method and a system for transmitting Ethernet service packets on a Resilient Packet Ring (RPR) network. The present invention determines a transmission path in the RPR network for the Ethernet service when the RPR network receives the Ethernet service to be transmitted, and transmits the Ethernet service packet in the RPR network through the transmission path. With the present invention, the Ethernet private line service can be transmitted in the RPR network still through the private line, thus satisfying the requirement of the Ethernet Virtual Private Line (EVPL) service. The present invention guarantees the security of private line service during the network transmission, which completely reflects the advantages, e.g. security and reliability, of the private line service; meanwhile, after the transmission path and the bandwidth of the Ethernet private line service in the RPR network are uniquely determined, the present invention can effectively guarantee the bandwidth utilization of the transmission network.</p> |
