Abstract

The invention provides a method and a system for transmitting data between local area networks. The system comprises two special routers, wherein the two special routers are connected with an Ethernet network tunnel by a main network special line and a spare network special line, each special router is connected with a local area network router of the local area network and comprises a control device, and the control device is used for controlling the special routers to adopt the main network special line and the spare network special line and controlling data transmitted between two local area networks by the Ethernet network tunnel.

Description

technical field [0001] The invention relates to the field of network communication, in particular to a data transmission method and system between local area networks. Background technique [0002] figure 1 It is a schematic diagram of a network structure of an enterprise headquarters and an enterprise branch in the prior art. figure 1 Among them, the network of the same enterprise can have at least two networks due to different deployment locations, which are called the enterprise headquarters and the enterprise branch. Among them, the enterprise branch and the enterprise headquarters each deploy an enterprise router, and the enterprise applies for a dedicated network line from the operator. , you can directly connect the enterprise routers of the headquarters and branches, and only need to configure IP addresses on the two routers. The network dedicated line means that the network service provider provides a dedicated channel for the user, so that the user's data transmi...
