Message sending method and device

Abstract

The invention provides a message sending method and device. The method and the device can be applied to any member device of any station in a resilient packet ring RPC network. The method comprises the steps of receiving Ethernet unicast massages; searching an RPR MAC (Media Access Control) addresses corresponding to the target addresses of the Ethernet unicast massages; searching corresponding unicast RPR aggregation rings according to the searched RPR MAC addresses; calculating a first ring selection hash value; when the first ring selection hash value matches an RPR logic port in the searched unicast RPR aggregation rings, sending the Ethernet unicast massages to the member devices on an RPR single ring corresponding to the RPR logic port matching the first ring selection hash value, wherein the member devices belongs to a local station; and when the first ring selection hash value matches local RPR single ring outcoming interfaces in the searched unicast RPR aggregation rings, packaging the Ethernet unicast massages into RPR unicast messages according to searched RPR MAC unicast addresses, and sending the RPR unicast messages through local RPR single ring outcoming interfaces matching a second unicast hash value. Message forwarding loads are shared in the RPR network.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a message sending method and device. Background technique [0002] With the rapid development of Ethernet technology, various equipment manufacturers have introduced 40G and 100G Ethernet interfaces, while the standard Resilient Packet Ring (RPR) can only support 10G ports, which limits the capacity of traffic transmission in Ethernet. Bandwidth; therefore, the RPR logical ports can be aggregated at the Ethernet level to use multiple RPR logical ports to share traffic, thus solving the above problems. [0003] After the upper layer completes the ring selection, it sends the traffic to the Media Access Control (MAC) entity of the corresponding RPR single-ring site. The port is forwarded and sent to other RPR single ring sites in the selected RPR single ring; when the destination site on the selected RPR single ring fails, the upper layer cannot perceive the topology...

Problems solved by technology

[0003] After the upper layer completes the ring selection, it sends the traffic to the Media Access Control (MAC) entity of the corresponding RPR single-ring site. The port is forwarded and sent to other RPR single ring sites in the selected RPR single ring; when the destination site on the selected RPR single ring fails, the upper layer cannot perceive the topology change of the RPR single ring and will not re-select the ring , so that traffic cannot be successfully sent to the destination site
