Abstract

The present invention relates to a data transmission system and method, wherein the system includes a first switching device interconnected with a first user service system, and a second switching device connected with a second user service system; the first switching device and the second A main dedicated data line and a backup data dedicated line are set between the two switching devices; wherein, the backup data dedicated line is a wireless data dedicated line; the first switching device is used to receive the target private network data sent by the first user service system, and detect the primary Whether the dedicated data line is interrupted, so that when the main dedicated data line is interrupted, the target private network data is transparently transmitted to the second switching device through the standby data dedicated line, and the second switching device sends the target private network data to the second user service system. The present invention can realize the networking of the two-layer private network of the first switching device and the second switching device, can realize the backup protection of the dedicated data line, greatly reduce the operation cost of the dedicated line, and the time required for the opening of the wireless data dedicated line is short, which can meet business requirements .

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a data transmission system and method. Background technique [0002] Group data dedicated line service is a group business launched by telecom operators for group customers. It is also called circuit leased line. Video conferencing, real-time image monitoring, etc. figure 1 It is a typical scenario for group users to use the operator's data dedicated line service. The user rents the operator's dedicated line to connect Layer 3 switching equipment A and Layer 3 switching equipment B, and then provides mutual services for user service system A and service system B located in different locations. Lines of communication. [0003] In the existing network, failure of transmission equipment or physical interruption of optical cables may lead to interruption of leased line services, but data leased lines are of great significance to certain industry customers to ensure t...
