Embodiment Construction

[0033] The data communication between the main control board and the service board of the traditional transmission equipment adopts uninterrupted sending of inter-board information messages, which will occupy a large amount of inter-board bandwidth and affect the transmission efficiency of other data (such as service data) between the boards. In addition, the messages between the load boards mostly adopt a method of defining a message format by one message, and each message format adopts a fixed format, and the message length is also fixed. In this way, there are many types of messages for inter-board communication, and there are multiple types of message encapsulation and implementation, and there are also multiple types of message receiving and parsing. However, the message adopts a fixed format and fixed length, which is not easy to expand and cut, and consumes the bandwidth of inter-board communication.

[0034] In order to solve the above problems, embodiments of the pres...

Abstract

The invention provides board-to-board information transferring method and device, relating to the field of optical transport equipment and solving the problem that board-to-board information messages occupy excessive bandwidth to influence other data transfer. The method comprises the steps of: detecting and recording board-to-board information to be sent; and repeatedly sending changed board-to-board information by using a first time interval when detecting the changed board-to-board information. The technical scheme provided by the invention is suitable for the equipment controlled by a main control board.

Description

technical field [0001] The invention relates to the field of optical transmission equipment, in particular to a method and device for transmitting information between boards in the equipment. Background technique [0002] The system architecture of the transmission equipment mostly uses the main control board to complete the configuration of the entire system. At the same time, the main control board is used to monitor the system status, alarm information and performance data in real time. Therefore, there must be real-time information between the main control board and the business processing board. Reliable Delivery Requirements. How to effectively utilize the bandwidth of the inter-board communication channel to transmit information reliably in real time has become a part of the system design that must be considered. [0003] The data communication between the main control board and the service board of the traditional transmission equipment adopts uninterrupted sending ...
