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 invention discloses a message transmission method and a device. The method includes that an edge bridge device receives a first message packaged by generic routing encapsulation (GRE) from a gateway device. The edge bridge device unbinds the first message GRE and a third message is obtained. According to an objective internet protocol (IP) address, a corresponding relation of the IP address and a multi-access computer (MAC) address in a local terminal device maintained in a local routing table is checked. After the MAC address corresponding to the objective IP address of the third message is ensured, the message is sent. The message transmission method and the device can normally transmit messages to be sent among different terminal devices.

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 (Spanning Tree Protocol, 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 technologi...
