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; The process of querying the MAC address table by the destination MAC address makes the above process impossible, that is, the packet sent from host 1 to host 2 cannot be forwarded normally.

Embodiment Construction

[0092] 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.

[0093] 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, when the terminal device is the sending end device, the edge bridge device is the source end device, and when the terminal device is the receiving end device, t...

Abstract

The invention discloses a message transmission method and device. The method includes that a generic route encapsulation (GRE) first message from an edge bridge device is received by a gateway device, and the first message is decapsulated to obtain a second message; the gateway device searches for a local routing list according to a destination internet protocol (IP) address of the second message; the gateway device performs GRE on the second message to generate a third message according to the found IP address and a media access control (MAC) address of the edge bridge device, and the destination IP address of the second message corresponds to the found IP address and the MAC address of the edge bridge device; and the gateway device sends the GRE third message to a corresponding edge bridge device. By means of the message transmission method and device, messages required to be transmitted among different terminal devices can be normally forwarded.

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...
