Problems solved by technology

[0003] When two devices connected to the interface on the LAN side communicate with the same device connected to the interface on the WAN side through the virtual interface at the same time, both virtual interfaces will learn the MAC address of the device connected to the WAN-side interface, which will cause communication failures. confusion

Embodiment Construction

[0030] Such as figure 1 Shown is a multi-service communication system 10 according to an embodiment. The multi-service communication system 10 includes a gateway device 100, a local terminal device 200 and a remote server 300.

[0031] The gateway device 100 has multiple local area network ports 120 and one wide area network port 140. Multiple terminal devices 200 are connected to the LAN port 120 of the gateway device 100, and the server 300 is connected to the WAN port 140 of the gateway device 100.

[0032] The terminal device 200 may be a network device such as a set-top box, a computer, VOIP, and Global Eye. The terminal devices 200 are all connected to the gateway device 100 through the physical interface of the gateway device 100, that is, the LAN port 120. In this embodiment, the LAN port 120 identifies the usage purpose to distinguish its service type.

[0033] The server 300 may be a network device such as a media server, a network server, a voice server, and a global ey...

Abstract

The invention discloses a bridging device based on a linux operation system. The bridging device comprises at least two local area network port processing modules and at least two wide area network port processing modules. At least two local area network port processing modules are connected with at least two local area network ports in a one-to-one correspondence mode to receive data from at least two local area network ports or transmitting data packages to at least two local area network ports. At least two wide area network port processing modules are connected with the same wide area network port to transmit data to the wide area network port or receive data packages from the wide area network port. Each local area network port processing module is bound with only one wide area network port processing module correspondingly. A communication method of the bridging device is further disclosed. By means of the bridging device and the communication method, communication disorder is avoided.

Description

Technical field [0001] The invention relates to network communication technology, in particular to a bridge device based on a linux operating system and a communication method of the bridge device. Background technique [0002] In digital subscriber line (Digital Subscriber Line, DSL) gateway terminal products, generally, multiple local area network (Local AreaNet, LAN) side interfaces and one wide area network (Wide Area Net, WAN) interface are supported. In order to realize multiple service types, multiple virtual interfaces need to be established on a WAN interface to realize multiple service control and differentiation. At the same time, in order to realize that all LAN-side interfaces can access the gateway device through the same IP address, usually the LAN-side interface and virtual interface are stored in the same bridge device. [0003] When two devices connected to the LAN side interface communicate with the same device connected to the WAN side interface through the vir...
