Embodiment Construction

[0036] In order to make the objectives, technical solutions, and advantages of the present invention clearer, the following further describes the present invention in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention.

[0037] See figure 2 , The user-based multi-tunnel transmission device proposed by the present invention exists as a kernel module under the Linux system. Running in the kernel space, it realizes different tunnel forwarding according to different user services, and forwarding processing of user data upstream and downstream packets. The execution of the fast tunnel forwarding module is controlled by the control module. Module in the system such as figure 2 Show:

[0038] a. Control module: used for users to issue configuration commands, such as opening or closing a tunnel service;

[0039] b. T...

Abstract

The invention discloses a multi-tunnel transmission device based on user service. The device comprises a control module for users to send configuration orders, a tunnel selection module for analyzing characteristics of messages, and forwarding the messages to different tunnels according to the nature of the messages when uplink and downlink messages enter the system, a first interface drive module for receiving data messages on a wireless side, a second interface drive module for receiving data messages on a wired side, a quick turning module for packing and unpacking tunnels of control and provisioning of wireless access points (CAPWAP) message headers, a business module for packing and unpacking tunnels of corresponding business message headers, and an internet protocol (IP) forwarding module for packing internet protocol message headers, sub-sheets and routers. The device realizes forwarding of various types of different tunnels, improves forwarding efficiency of business data, and reduces forwarding expenditure.

Description

Technical field [0001] The invention relates to the field of data transmission, in particular to the field of multi-tunnel data transmission. Background technique [0002] Tunneling is a way of transferring data between networks by using the infrastructure of the Internet. The data (or load) transferred using the tunnel can be data frames or packets of different protocols. The tunneling protocol re-encapsulates the data frames or packets of other protocols and then sends them through the tunnel. The new frame header provides routing information to transfer the encapsulated load data through the Internet. [0003] The tunnel mentioned here is similar to a point-to-point connection. In this way, network services from many information sources can be transmitted through different tunnels in the same infrastructure. The tunnel technology uses the point-to-point communication protocol instead of the exchange connection, and connects the data address through the routing network. [000...
