Abstract

The invention provides a message transmission method and device. The method comprises the steps of: maintaining the corresponding relationship of a first PEX device and the MAC address of a host in amapping table item, wherein the host is a host connected with the first PEX device; and, receiving a first type of data messages sent by a second PEX device, querying the mapping table item through the destination MAC address of the first type of data messages, so that the first PEX device corresponding to the destination MAC address is obtained, and sending the first type of data messages to theobtained first PEX device. By means of the technical scheme in the invention, table item resources of a CB device can be saved; processing resources of the CB device can be saved; and thus, the forwarding pressure of the CB device can be reduced.

Description

technical field [0001] The present application relates to the technical field of communications, and in particular to a message transmission method and device. Background technique [0002] Such as figure 1 As shown, it is a schematic diagram of a vertically stacked network. Multiple PEX (Port Extender, port extension) devices can be connected to a CB (Controlling Bridge, Control Bridge) device, and each PEX device can be virtualized into a remote service board of the CB device. It is managed by the CB device in a unified manner. Using this virtualization technology can increase the interface density of CB devices, simplify the network topology, and reduce network maintenance costs. [0003] At present, after receiving the message sent by the host, the PEX device directly sends the message to the CB device, and the CB device uses the forwarding entry to send the message. In the above process, the PEX device does not need to maintain any forwarding entries, and the PEX dev...
