Problems solved by technology

Usually, the router can process a certain number of packets per second, that is, the packet forwarding efficiency of the router is certain. When the packet length is small, the transmission capacity of the transmission network will inevitably be reduced.

Embodiment Construction

[0057] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0058] The key of the present invention is to carry out batch encapsulation to passenger message, namely, a plurality of (in the present invention, multiple refers to two or more) passenger message is bundled, and adds encapsulation protocol header and transmission protocol header Then send the message. In this way, the network bandwidth consumption of the tunnel transmission path is reduced, and the packet forwarding capability of the tunnel is improved.

[0059] refer to image 3 In the tunnel-based message forwarding method of the embodiment of the present invention, the following steps are performed on the encapsulating router:

[0060] Step 301: After bundling at least two passenger messages, obtain the in-tunnel message;

[0061] The so-call...

Abstract

The invention provides a message forwarding method based on tunnel and a router thereof. The method comprises the following steps: at least two passenger messages are bundled to obtain a tunnel entering message; a packaging protocol header and a transferring protocol header are added to the tunnel entering message to generate a tunnel message; the packaging protocol header is provided with an identification indentifying that the tunnel message is a batch packaging message; the tunnel message is forwarded. The invention can save bandwidth occupation of a tunnel transferring path and improve the message forwarding ability of a tunnel.

Description

technical field [0001] The invention belongs to the technical field of data communication, and in particular relates to a tunnel-based message forwarding method and a router. Background technique [0002] Tunnel technology is to encapsulate data packets of certain network layer protocols (such as IPv4, IPv6 and IPX), so that these encapsulated data packets can be transmitted in another network layer protocol (such as IPv4). Generic Routing Encapsulation (GRE) tunnel is a kind of tunnel technology, and the GRE protocol belongs to the third layer tunnel protocol. [0003] A GRE tunnel is a virtual point-to-point connection that provides a transmission path for encapsulated data packets. The two ends of the GRE tunnel respectively encapsulate and decapsulate the data packets. [0004] by figure 1 Let’s take the network as an example to illustrate the transmission process of X-protocol packets across the IP network and in the GRE tunnel: [0005] 1. Add packaging process [...
