Method and system for synchronizing comprehensive communication channel work mode

Abstract

The invention discloses a method for synchronizing a GCC (GNU Computer Compiler) work mode. A sending end sends self used GCC work mode codes to a receiving end through overhead bytes or monitor information; the receiving end reads the GCC work mode codes in the overhead bytes or the monitor information to obtain the GCC work mode; and the receiving end regulates the self used GCC work mode based on the obtained GCC work mode. The invention also discloses a system for synchronizing the GCC work mode. By adopting the method and the system, the GCC work mode of the receiving end is automatically synchronized with that of the sending end, and the efficiency and the stability of signal transmission are enhanced.

Description

technical field [0001] The invention relates to the field of optical transmission network (OTN), in particular to a method and system for synchronizing working modes of a general communication channel (GCC). Background technique [0002] The optical transport network is an optical layer transport network based on wavelength division multiplexing technology. The new generation of "digital transmission system" and "optical transmission system" regulated by the proposal of the National Institute of Technology, which combines the advantages of Synchronous Digital Hierarchy (SDH) and Wavelength Division Multiplexing (WDM), is the backbone transmission network of the next generation. [0003] Both service signals and non-service signals in the OTN are transmitted in a frame structure, and abundant overhead bytes are defined, and the overhead bytes are bytes reserved for each frame to transmit specific information. The G.709 standard defines three fields in the OTN overhead byte. ...

Problems solved by technology

[0004] When GCC transmits information, the GCC working mode of the sending end needs to be consistent with the GCC working mode of the receiving end, that is, the channel and the transmission content are consistent. The GCC working mode is the content transmitted by GCC, which generally includes transmission monitoring channel information and transmission dedicated communication Information, monitoring channel information and dedicated communication information are jointly transmitted in three GCC working modes. If the GCC working modes of the sending end and the receiving end are inconsistent, the information transmission will be interrupted because the receiving end cannot compile the received information of the sending end.

At present, in practical applications, the GCC working mode of the sending end and the GCC working mode of the receiving end are generally set separately. Therefore, it often occurs that the GCC working mode settings of the sending end and the receiving end are different, or due to misoperation, etc., resulting in information not being available. correct transmission
