Remote management implementation method, remote management implementation system, general communication channel (GCC) overhead processing method and GCC overhead processing device

Abstract

The invention discloses a remote management implementation method, a remote management implementation system, a general communication channel (GCC) overhead processing method and a GCC overhead processing device. The remote management implementation method comprises the following steps of processing a GCC overhead; establishing a remote management channel; performing remote management through the established remote management channel. According to the remote management implementation method, the remote management implementation system, the GCC overhead processing method and the GCC overhead processing device, by using the remote management channel established by a GCC overhead channel, an additional bandwidth special for remote management is eliminated, so that the cost is reduced, the hardware design is simplified, and the management difficulty and the bandwidth waste are reduced.

Description

technical field [0001] The present invention relates to optical transport network technology, in particular to a method and system for realizing remote management in an optical transport network (OTN, Optical Transport Network), and a GCC overhead processing method and device. Background technique [0002] OTN is a transport network that organizes networks at the optical layer based on wavelength division multiplexing technology. OTN technology solves the problems of SDH (Synchronous Digital Hierarchy) based on VC-12 / VC4 crossover particles are too small, scheduling is more complex, and does not meet the needs of large-grain service transmission; it also partially overcomes the dense wavelength division multiplexing ( WDM, Dense Wavelength Division Multiplexing) system fault location is difficult, and the network survivability means and capabilities it can provide are weak. [0003] OTN provides the transmission, multiplexing, routing, management, and monitoring of customer...

Problems solved by technology

[0005] However, since only the location of the GCC overhead is defined in the ITU-G.709 proposal, and how to use the GCC overhead is not described, there is no uniform standard for the use of the GCC byte. Therefore, in the prior art, the GCC overhead byte There is no specific implementation plan for the use of

In addition, because the GCC signal provided by the framing chip is usually a bit stream or register data, there is no byte boundary and frame positioning, so it is impossible to obtain richer and more effective management information by directly using the GCC byte
