Message forwarding method, system and routing switch

Abstract

The invention provides a message forwarding method and system as well as a routing switch. The message forwarding method comprises steps of inquiring an MAC (Media Access Control) chart and obtaining an identification of a first target routing switch by a source routing switch according to a received target MAC address of the current Ethernet data frame; inquiring a neighbor connecting list of the first target routing switch and obtaining an identification of a second routing switch directly connected with the first target routing switch by the source routing switch according to the identification of the first target routing switch; and forwarding the Ethernet data frames and following received other Ethernet data frames with the same MAC address to a terminal device corresponding to the target MAC address through the first target routing switch and the second target routing switch by the source routing switch according to a TRILL (Transparent Interconnection of Lots of Link) routing table. According to the technical scheme of the invention, the waste of link bandwidth resources can be reduced, and the utilization rate of the link bandwidth resources is improved.

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] The data center (Data Center; referred to as: DC) achieves the goal of data sharing and utilization by realizing a unified data definition and naming standard, and a centralized data environment. With the rise of cloud computing and cloud storage, as the backing of the cloud, the data center network is also undergoing technological upgrading and transformation of "change for the cloud", and many new technologies have been proposed, including multi-link transparent transmission. Interconnection (Transparent Interconnection of Lots of Link; TRILL for short) is one of them. Currently, TRILL is gradually becoming the standard for data center network virtualization and is driving the development of data centers. [0003] A bridge running the TRILL protocol is usually called a routing switch (Route bridge; ...

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.
