Embodiment Construction

[0086] The present invention is used to realize communication between network elements of an optical network, and its main principle is to use an asynchronous clock processing method to solve the problem of clock synchronous tracking in the synchronous processing method in the prior art, that is, to add asynchronous processing to optical network transmission equipment such as OTU Units are used to implement asynchronous processing. In addition, the present invention also inserts the monitoring information of the communication between network elements into the predetermined overhead byte of the optical transmission signal and transmits it together with the service. The overhead byte used may be any DCC byte, or any other available byte. Because it is a channel-associated transmission method, the dependence on OSC can be avoided, and the networking cost can be greatly reduced.

[0087] The following is a detailed description. For the convenience of description, the uplink direc...

Abstract

The invention is in use for transferring monitored information mainly between net elements of optical network. The information transferring equipment includes first asynchronous processing element, second asynchronous processing element, first overhead processing element and second overhead processing element. Through the first asynchronous processing element and the second asynchronous processing element, the information transferring equipment transfers message in asynchronization so as to realize communication between net elements. Moreover, the invention also discloses relevant information transfer method and system the invention avoids a series of problems brought by synchronous mode such as penetration of time clock tracking.

Description

technical field [0001] The present invention relates to the technical field of optical communication, and more specifically, the present invention relates to an information transmission device, method and system for realizing communication between network elements in an optical network. Background technique [0002] At present, optical fiber communication technology is developing rapidly. The optical transmission network with add-drop multiplexing and cross-connection functions based on WDM (Wavelength Division Multiplexing) technology has great advantages such as easy reconfiguration and good scalability. , has become the development direction of the future high-speed transmission network. The application of the WDM technology is to divide the available wavelength band of the optical fiber into several small channels, and each channel corresponds to a wavelength, so that single-wavelength transmission becomes multi-wavelength simultaneous transmission, thereby greatly incre...
