Embedded control channel based data communication channel transmitting method and apparatus

Abstract

The present invention provides a transparent transmission method and device of data communication channel based on embedded control channel. The method comprises the steps as follows: the source transparent transmission Gateway is provided with a transparent transmission relationship of source to destination which is stored in the source transparent transmission Gateway; in the source transparent transmission Gateway, the source data communication channel byte of source optical port is acquired according to the transparent transmission relationship of source to destination, and the source data communication channel byte is sealed in the embedded control channel; in the embedded control channel, the destination address is filled as the destination transparent transmission Gateway, and the service type is data communication channel transparent transmission, and the transparent transmission destination is destination data communication channel byte; in the destination transparent transmission Gateway, the embedded control channel is analyzed, and the destination Gateway is defined as the destination address, and the obtained service type is data communication channel transparent transmission; the transparent transmission destination is extracted from the embedded control channel, and the source data communication channel byte is written in the overhead of destination optical port according to transparent transmission destination.

Description

technical field [0001] The present invention relates to a data communication channel transparent transmission method based on an embedded control channel for transparently transmitting embedded control channel messages of a source client network to a target client network through multiple transparent transmission gateways in a synchronous digital transmission network environment and device. Background technique [0002] The construction of optical communication networks has spread all over the world during the accumulation of construction over time. With the accumulation of network construction and the continuous replacement of equipment manufacturers, the number of equipment and types of equipment operating in the network is increasing, and the network layout of mixed networking of network equipment from different manufacturers increasingly complex. As a basic bearer network, network monitoring is very important. With the intensified competition among operators, the demand...

AI Technical Summary

Problems solved by technology

[0004] There are two problems with the above method of DCC transparent transmission: the first problem is that when there are many devices in the mixed network, the configuration of DCC transparent transmission is very complicated. For transparent transmission through the N-terminal devices in the network, it is necessary to configure N*3 transparent transmission to the optical port. When the network network is changed, a large reconfiguration is required, and the workload of network configuration is relatively large: and The second problem is that the DCC transparent transmission relationship of the above methods is fixed, that is, the device can only transparently transmit a certain DCC byte of a certain optical port to a certain DCC byte of another optical port. The transmitted DCC is interrupted, which causes the network management to be disconnected, and the network fault cannot be checked and recovered in time.
