METHOD AND SYSTEM FOR DATA TRANSMISSION IN ETHERNET

摘要

The embodiments of the present invention provide a method and system for data transmission in an Ethernet. The method is applied to an Ethernet service processing system, wherein the Ethernet service processing system includes at least two exchange boards and one service board, and each exchange board is linked to the service board through a physical link. The method includes: when faults occur on the Ethernet data transmission in the first exchange board, a state indication signal is transmitted to the service board through the physical link from the first exchange board to indicate that faults occur on the Ethernet data transmission in the first exchange board, so that the service board stops the Ethernet data exchange via the first exchange board, and performs the Ethernet data exchange via the second exchange board. In the embodiments of the present invention, the exchange boards transmit the state indication signal carrying the working state information of the exchange boards to the service board through the physical link, which enables the service board to obtain the working state information of the exchange boards in real time, and to select other proper exchange boards for data transmission according to the working state information of each exchange board, thus reducing the influence degree to the service.
