Message forwarding method, system and routing switch

Abstract

The invention provides a message forwarding method, system and routing switch. The method includes: the source routing switch queries the MAC table according to the received destination MAC address of the current Ethernet data frame, and obtains the identifier of the first destination routing switch; the source routing switch queries the first destination routing switch according to the identifier of the first destination routing switch The neighbor direct connection list of the switch obtains the identification of the second destination routing switch directly connected to the first destination routing switch; the source routing switch uses the TRILL routing table to transfer the Ethernet data frame to the subsequent received Ethernet data frame with the same destination MAC address. The network data frame is forwarded to the terminal device corresponding to the destination MAC address through the first destination routing switch and the second destination routing switch. The technical scheme of the invention can reduce the waste of link bandwidth resources and improve the utilization rate of link bandwidth resources.

Description

technical field [0001] The invention relates to data communication technology, in particular to a message forwarding method, system and routing switch. Background technique [0002] Data Center (abbreviated as: DC) achieves the goal of data sharing and utilization by realizing unified data definition and naming standards and a centralized data environment. With the rise of cloud computing and cloud storage, as the support of the cloud - the data center network is also undergoing technological upgrading and transformation of "changing for the cloud", thus proposing many new technologies, multi-link transparent transmission Interconnection (Transparent Interconnection of Lots of Link; TRILL for short) is one of them. At present, TRILL is gradually becoming the standard of data center network virtualization and promoting the development of data centers. [0003] A bridge (bridge) running the TRILL protocol is generally called a route switch (Route bridge; Rbridge for short), ...

AI Technical Summary

Problems solved by technology

[0004] In the process of realizing the present invention, the inventor found that there are at least the following problems in the prior art: In the above-mentioned message forwarding process, for two Rbridges sharing a link, one of them will be selected in advance according to the forwarding Rbridge election rules. One Rbridge acts as the forwarding Rbridge, and then the forwarding Rbridge selects one of the two Rbridges as the forwarder of the message on the link and announces the information of the forwarder Rbridge, and the other Rbridge forwards the message to the shared link. Packets on the road are not forwarded and are only used for link backup. The utilization rate of link bandwidth resources is low, resulting in a waste of bandwidth resources.
