Embodiment Construction

[0034] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0035] The main idea of ​​the present invention is to improve the existing TRILL forwarding technology and enter the penultimate hop decapsulation mechanism. That is, on the forwarding path, the decapsulation processing of the TRILL message is handed over to the first RB connected to the ERB (that is, the penultimate RBridge), and the decapsulated...

Abstract

The invention discloses a data transmission method and device of a multilink transparent transmission interconnection network, wherein the method comprises the following steps: a TRILL (Trill) exchanger receives a well-known unicast data frame, wherein the well-known unicast data frame comprises a TRILL data frame or an Ethernet data frame; if the TRILL data frame is received, the TRILL exchanger judges whether the TRILL exchanger is the TRILL exchanger at the penultimate hop of the TRILL data frame according to the information carried in the TRILL data frame and a TRILL forwarding table; and if a judging result is positive, the TRILL exchanger unpacks the TRILL data frame to obtain the Ethernet data frame and transmits the Ethernet data frame to the last hop of TRILL exchanger. By using the method, the problem that the ERB (Edge Router Bridge) processing performance in the traditional TRILL network turns into the performance bottleneck of Trill Campus can be solved.

Description

technical field [0001] The present invention relates to the field of data communication, in particular to a method and device for transmitting data in a Transparent Interconnection of Lots of Links (TRILL for short) network. Background technique [0002] Data Center (DC for short) 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 backing of the cloud—the data center network is also undergoing technological upgrading and transformation of "changing for the cloud", thus proposing many new technologies, TRILL is one of them one. At present, TRILL is gradually becoming the standard of data center network virtualization and promoting the development of data centers. [0003] A switch running the TRILL protocol is called a route switch (Route Bridge, RBridge for short), that is, a bridge device with routing and forwarding charac...
