Ethernet data transmission method via RPR transmission

Abstract

Coincidence relation between MAC address of Ethernet and MAC address of node of RPR network is recorded in MAC address forwarding table in second layer of Ethernet. Thus, when service message in Ethernet is needed to pass through RPR network to carry out transmission, the invention can determine information of MAC address of destination node in RPR network for the said message based on MAC address forwarding table, in time of carrying out forwarding process in second layer by Ethernet. In procedure for loading message to RPR network, it is not needed for message to carry out mapping process procedure between message in Ethernet and RPR node, instead, relevant packaging process based on RPR protocol can be carried out directly to realize strict route selection for Ethernet data to be transferred on PRP network. Thus, the invention solves issue of collaborative work between transmission process in second layer for Ethernet message and RPR network.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a method for transmitting Ethernet data through an elastic packet ring. Background technique [0002] With the vigorous development of data services, the traditional SDH (Synchronous Digital Hierarchy) transmission network is required to support data services. EOS (Ethernet over SDH, SDH carrying Ethernet services) has been widely used and developed due to its high bandwidth utilization. The RPR technology improves the traditional EOS networking method, realizes the fair statistical multiplexing of the ring network bandwidth, and provides a relatively complete protection switching mechanism. Therefore, the transmission of the physical layer of data by using the elastic packet ring RPR has been achieved. More and more widely recognized and applied. [0003] However, the inherent characteristics of the ring network determine that all nodes on the same ring share the ...

Problems solved by technology

[0009] This method simplifies the front-end access processing for the message, that is, there is no need to determine the transmission path of the front-end message on the RPR, and the transmission process can be performed directly. However, since all services are broadcast on the RPR Therefore, it will occupy a large amount of RPR bandwidth resources, that is, the ring network bandwidth resources are wasted, and the bandwidth reuse feature of RPR technology cannot be perfectly reflected.

That is to say, although this technical solution can realize the combination of Ethernet Layer 2 forwarding service and RPR in theory, it is not a good realization of Ethernet and RPR intercommunication due to the above reasons in the actual application process. Program
