Embodiment Construction

[0036] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described below are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0037] figure 2 shows a flow chart of a method for GCC rate adjustment provided by an embodiment of the present invention, as shown in figure 2 As shown, the method includes:

[0038] Step 201: the service transmission unit sends its own GCC information to the layer 2 network unit;

[0039] Step 202: The Layer 2 network element determines the highest GCC rate for transmitting monitoring information by using the GCC information.

[0040] The step 201 is specifically:

[0041] The service transmission unit encapsulates the GCC information including the GCC service rate type and the number of GCCs used into a private message, and sends the private messa...

Abstract

The invention discloses a method and device for adjusting the rate of a general communication channel (GCC). The method includes: a service transmission unit sends its own GCC information to a layer-2 network unit; the layer-2 network unit uses the GCC information to determine its The maximum rate at which GCC sends monitoring messages. The invention can solve the packet loss problem caused by the bandwidth of the GCC service in the electrical monitoring channel being smaller than the bandwidth of the second-layer network in the wavelength division monitoring system, and improves the stability and reliability of the wavelength division monitoring system.

Description

technical field [0001] The present invention relates to the field of transmission technology, in particular to a method for adjusting the rate of a general communication channel (General Communications Channel, GCC) and a related device. Background technique [0002] In the WDM monitoring system, there are generally two types of optical monitoring channels and electrical monitoring channels. The electrical monitoring channel is implemented through a general communication channel (General Communications Channel, GCC) in an optical transport network (Optical Transport Network, OTN) service overhead. [0003] figure 1 A schematic diagram of the electrical monitoring channel of the WDM monitoring system provided by the prior art is shown, as shown in figure 1 As shown, the networking form between WDM monitoring systems generally includes a three-layer network and a two-layer network. Among them, the network element main control unit is used for the management and control of n...
