Problems solved by technology
[0005] The above-mentioned existing methods are simple to implement and can improve the reliability of interface status reporting to a certain extent. However, when the data channel is busy, it is often impossible to ensure that the control board can finally receive the message of interface status change correctly.
And the method of blindly resending regardless of whether the other party receives the status message will only increase the congestion of the channel
Therefore, the existing method cannot solve the problem of accurately reporting the state of the circuit board interface

Embodiment Construction
[0018] The present invention will be described in detail below by taking the circuit board reporting the interface state information on its own board to the system main control board as an example.
[0019] The present invention adopts such a solution. When the circuit board reports the interface status information to the system, the interface information of the interface should be stored at the same time. In this way, when the interface status information is reported unsuccessfully, the current status of the interface can be stored according to the stored interface information. Resend the information to the system; when the interface status of the circuit board changes, report the current status information of the interface after the change to the system. Since it is not known whether the reported information can be received by the system in practice, it is necessary to report the information while reporting the information. Check whether the information of the interface has b...

This invention discloses a method for reporting the interface state information. With the method the circuit board stores the information of the interface as reporting the interface state to the system; when the interface state changes, the changed current state information is reported to the system, meanwhile checks if the information of the interface is stored, if not, then stores the information; meanwhile the system feedbacks the reply message for receiving the interface information after receiving the interface state information. The circuit board decides if the stored interface information needs to be deleted according to the reply message, and also report the above interface current state information to the system on time according to the stored interface information.
Description
technical field [0001] The invention relates to an information transmission method in a communication system, in particular to a transmission method for communication interface state information in a distributed routing switching system. Background technique [0002] In a distributed routing and switching system, the transmission of information between boards is based on the premise of correctly knowing the status of the peer interface. For example, the main control board of the system needs to perform data scheduling operations according to the status of the physical interfaces on each circuit board. Since the physical interface on the above-mentioned circuit board may have various states, such as data upload state and data download state, which respectively indicate that the circuit board is in the state of reporting data or downloading data, these states are passed through UP / The DOWN (upload / download) status message is reported to the main control board of the system. T...
