Problems solved by technology

[0035] In the above steps 3 and 4, the gateway device needs to use the destination IP address to query the routing table first, and then use the destination MAC address to query the MAC address table; however, currently, some chips from existing manufacturers cannot use the destination IP address to query the routing table first. Then use the destination MAC address to query the processing process of the MAC address table, so that the above process cannot be realized, that is, the message sent by host 1 to host 2 cannot be forwarded normally.

Embodiment Construction

[0087] The following will clearly and completely describe the technical solution of the present invention in conjunction with the accompanying drawings of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0088] Aiming at the problems existing in the prior art, the embodiment of the present invention proposes a message transmission method, which is applied to a large layer-2 network including a terminal device, an edge bridge device and a gateway device, wherein the edge bridge device and the terminal device Direct connection; the gateway device encapsulates the message with GRE and sends the GRE-encapsulated message to the edge bridge device, so as to avoid the processing flow of fir...

Abstract

The present invention discloses a message transmission method and equipment. The method comprises: an edge bridge device receives a GRE-encapsulated first message from a gateway device; the edge bridge device decapsulates the first message from GRE to obtain the first message For the third message, according to the destination IP address of the third message, look up the corresponding relationship between the IP address and the MAC address of the local terminal device maintained in the local routing table, determine the MAC address corresponding to the destination IP address of the third message, and then forward it . In the embodiment of the present invention, messages that need to be transmitted between different terminal devices can be forwarded normally.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a message transmission method and equipment in a large-scale two-layer network. Background technique [0002] STP (SpanningTreeProtocol, Spanning Tree Protocol) is used in the traditional three-tier data center architecture to optimize the path from the client to the server and support connection redundancy. Due to the convergence performance of STP, etc., the network size of STP generally does not exceed 100 switches. At the same time, because STP needs to block redundant devices and links, it also reduces the bandwidth utilization of network resources. Traditional STP-based backup equipment and link solutions can no longer meet the scale and bandwidth requirements of the data center, and the STP protocol's fault convergence time of several seconds to minutes cannot meet the reliability requirements of the data center. Therefore, it is necessary to have new technologies...
