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

Embodiment Construction

[0021] In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0022] figure 1 It is a schematic flowchart of the message sending method provided by the present invention, and the message sending method can be applied to any member device of any station in the RPR network. Such as figure 1 As shown, the message forwarding method includes:

[0023] Step 101, receiving an Ethernet unicast message.

[0024] Step 102, look up the RPR MAC address corresponding to the destination address of the Ethernet unicast message.

[0025] Step 103: Find the corresponding unicast RPR aggregation ring according to the found RPR MAC address.

[0026] Step 104, calculate the hash value of the first selected ring.

[0027] Step 105, whether the hash value of the first selected ring matches a RPR logical inte...

Abstract

The present invention provides a message sending method and device, which can be applied to any member device of any site in a resilient packet ring RPR network, wherein the method includes: receiving Ethernet unicast messages; searching for Ethernet unicast messages The RPR MAC address corresponding to the destination address; find the corresponding unicast RPR aggregation ring according to the found RPR MAC address; calculate the hash value of the first selected ring; One of the RPR logical ports in the selected ring matches, and sends Ethernet unicast packets to the member devices belonging to the site on the RPR single ring corresponding to the RPR logical port whose hash value matches the first selected ring; when the hash value of the first selected ring matches the The outbound interface of the local RPR single ring found in the unicast RPR aggregation ring matches, and the Ethernet unicast packet is encapsulated into an RPR unicast packet according to the found RPR unicast MAC address. RPR single-ring outbound interface sends; thus realizes load sharing of packet forwarding 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...
