Method, apparatus and system for forwarding packet

Abstract

The embodiment of the invention discloses a method, a device and a system for transmitting messages. The method comprises the following steps that an interface board transmits a first message received to a given service board according to a configured general route encapsulation GRE route information sent down by a master control board, and then the service board encapsulates the first message; the interface board receives the encapsulated first message transmitted by the service board and transmits the encapsulated first message to the outside according to the configured GRE route information sent down by the master control board; and the interface board receives a second message which is sent by the outside and responds to the encapsulated first message and transmits the second message to the service board according to the configured route information, and then the service board decapsulates the second message. By utilization of the embodiment of the invention, simultaneous transmission of a large number of messages to the same service board for treatment is avoided and the transmission efficiency is improved.

Description

technical field [0001] The present invention relates to the technical field of communications, in particular to a message forwarding method, device and system. Background technique [0002] With the wide application of the Internet, more and more enterprise users begin to pay attention to the huge resource pool of the Internet. Globally shared resources can provide different services for different customers. This diversity of development puts higher demands on information security. It is required that only authorized users can access the key business programs and data in the enterprise's internal system. Therefore, the enterprise's requirements for its own network construction, especially the security requirements, are also getting higher and higher. Based on this situation, the VPN (Virtua1Private Network, virtual private network) technology, VPN is different from the traditional network, it does not actually exist, but uses the existing public network, a virtual network fo...

Problems solved by technology

[0009]Currently, the processing capability of the centralized device is limited by the processing capability of the hardware, and the forwarding of the message is mostly based on the configuration of the Tunnel interface information on the main control board and the message. When it is sent to the main control board, it will be processed by the main control board. When the traffic of the message on the main control board is relatively large, it will seriously affect the forwarding efficiency of the message. This centralized architecture restricts the forwarding of the message Forwarding efficiency of processes and systems
