Embodiment Construction

[0052] The implementation of the technical solution will be further described in detail below in conjunction with the accompanying drawings.

[0053] The method of the embodiment of the present invention adopts the transmission verification scheme of the CFP MDIO MSA communication protocol, which can improve communication reliability, improve the correctness and reliability of data transmission, and prevent message loss and error. This embodiment is realized by cooperation between the host and the optical module. The host acts as the sender and sends the frame and carries the control instruction (such as the control instruction implemented by the operation code). The optical module acts as the receiver and receives the frame. According to the read control Instructions (such as control instructions implemented by opcodes) perform corresponding operations. Moreover, the frame includes a check frame, and the host and the optical module perform check calculations based on the same...

Abstract

The present invention discloses a transmission method and device based on management data input / output multi-source agreements, said method comprising: sending at least one frame, and a main computer indicating, in accordance with the operation code carried by the frame, to execute a read data operation or a continuous read data operation or a write data operation in regard to an optical module; said frame is used, during a check, at the main computer and at the optical module for respectively calculating a checksum, and it is determined, in accordance with the result of a comparison of the checksums, whether a checksum is correct, and the decision is made as to whether it is necessary to repeat said read data operation or continuous read data operation or write data operation.

Description

technical field [0001] The present invention relates to communication technology, in particular to a transmission method and device based on CFP Management Data Input / Output (MDIO, Management Data Input / Output) multi-source agreement (MSA, Multi Source Agreement). Background technique [0002] At present, in data transmission scenarios based on communication protocols, such as MDIO (Management Data Input / Output) multi-source agreement (MSA, Multi Source Agreement), there is no real-time verification of the data transmitted in read and write operations. , In communication, once a data transmission error occurs, it may cause unpredictable results. For example: an error occurs when setting the channel wavelength. When you want to set the channel wavelength to the fourth wave, due to interference during transmission, it may be received as the sixth wave. In this way, the fourth wave has no signal after multiplexing, and the sixth wave is two channels. The receiver will not be a...
