Method for transmitting network management and signaling information using Generic Framing Procedure

Abstract

The invention relates to a method for transmitting internet administrator instructions by employing general purpose frame procedures (GFP) characterized by that, the GFP administration and instruction function is expanded and reinforced, a GFP network administration frame and a GFP instruction frame are defined, wherein GFP client data frames, client administration frames and idle frames are subject to statistic multiplexing and transmission based on priority level, the priority levels for GFP network frames and GFP instruction frame transmission are configured to be the highest, and the GFP network administration frame and the GFP instruction frame are only transmitted when information exist instead of a timing basis.

Description

technical field [0001] The present invention belongs to the category of network technology, and is a method for transmitting network management and signaling information using general framing technology when the transmission network bears data and video services from the customer network, that is, adopting general framing procedures to provide the transmission network with in-band Methods for managing communication channels and signaling communication channels. Background technique [0002] In order to ensure the transmission requirements of the business, it is necessary to carry out effective monitoring and network management on the business transmitted in the transmission network. In the traditional implementation method, the management communication channel and the signaling communication channel are generally transmitted in an out-of-band channel, or the management communication channel and the signaling communication channel are transmitted in the in-band channel provid...

AI Technical Summary

Problems solved by technology

For example, the limitations of using the first method (using the out-of-band channel) are: 1) The management / signaling between network elements can depend on an external separate signaling network or public network, and the independence is poor; 2) ) Out-of-band management / signaling channels are less secure than in-band situations and are vulnerable to malicious attacks

[0004] By defining such a client signal failure message, the problem of lack of fault detection and fault location on the client side when carrying client services on the transport network can be solved, but such management and monitoring functions alone are not enough

Especially if the data is encapsulated into the GFP frame and transmitted directly in the WDM wavelength channel or directly in the optical fiber, there is currently no separate management / signaling communication channel defined
