<p>A method and an apparatus for realizing communication between single boards are provided by this invention. The method includes the steps: a sending single board adds a priority processing sign into a message encapsulated with emergency information when the message is being constructed, and preferentially sends the message via a management channel to a receiving single board according to the priority processing sign. After receiving the message, the receiving single board preferentially resolves the message encapsulated with the emergency information according to the priority processing sign. Wherein, the sending single board or the receiving single board is a main control board. By means of a soft HW channel established between the main control board and the service board and the chips stacking of the main control board, the present invention simplifies equipment, efficiently transmits information, saves the circuit at the back board, realizes quick protection switching, and achieves quick information transmission and protection switching on both links between the main control boards and between the main control board and the service board, thus improving the data communication capability and the protection ability of the system with the simple system structure.</p> |
