Abstract

Provided are a configuration method and apparatus, a binding method and apparatus, a device, a sending node, a receiving node, and a medium. The configuration method includes determining a multiplexing structure of an optical layer channel and configuring channel identification information for a target node according to the multiplexing structure. The channel identification information is used for instructing the target node to bind the optical layer channel.

First claim

What is claimed is:

1. A configuration method, applied by a network management device, comprising:
determining a multiplexing structure of an optical layer channel;
configuring channel identification information for a target node according to the multiplexing structure, wherein the channel identification information is used for instructing the target node to bind a local optical layer channel, and binding the local optical layer channel comprises binding a local channel layer interface and a local subchannel layer interface to generate an interface address at an channel layer and an interface address at an optical tributary signal assembly (OTSiA) layer for creating an optical layer path; and
delivering the channel identification information to the target node.

2. The method according to claim 1 , wherein the target node comprises a sending node; and
the sending node and a corresponding receiving node have an overhead channel used for transmitting the channel identification information.

3. The method according to claim 2 , wherein the channel identification information comprises following information of the sending node:
an optical layer adaptation interface local identifier;
a number of channels contained in an optical layer;
a channel local identifier;
a number of subchannels contained in a channel;
a subchannel local identifier; and
a subchannel peer-end local identifier.

4. The method according to claim 1 , wherein the target node comprises a sending node and a receiving node; and
configuring the channel identification information for the target node according to the multiplexing structure comprises:
configuring corresponding channel identification information for each target node according to the multiplexing structure.

5. The method according to claim 4 , wherein the channel identification information corresponding to the each target node comprises following information of the each target node:
an optical layer adaptation interface local identifier;
a number of channels contained in an optical layer;
a channel local identifier;
a number of subchannels contained in a channel; and
a subchannel local identifier.

6. A device, comprising:
at least one processor; and
a storage apparatus configured to store at least one program, wherein
when executed by the at least one processor, the at least one program causes the at least one processor to implement the configuration method according to claim 1 .

7. A non-transitory computer-readable storage medium storing a computer program, wherein the computer program, when executed by a processor, implements the configuration method according to claim 1 .

8. A binding method, applied by a sending node, comprising:
acquiring channel identification information from a network management device, wherein the channel identification information is configured by the network management device according to a multiplexing structure of an optical layer channel; and
binding a local optical layer channel according to the channel identification information, wherein binding the local optical layer channel comprises binding a local channel layer interface and a local subchannel layer interface to generate an interface address at an channel layer and an interface address at an optical tributary signal assembly (OTSiA) layer for creating an optical layer path.

9. A sending node, comprising:
at least one processor; and
a storage apparatus configured to store at least one program, wherein
when executed by the at least one processor, the at least one program causes the at least one processor to implement the binding method according to claim 8 .

10. The method according to claim 8 , wherein the channel identification information comprises following information of the sending node:
an optical layer adaptation interface local identifier;
a number of channels contained in an optical layer;
a channel local identifier;
a number of subchannels contained in a channel; and
a subchannel local identifier.

11. A non-transitory computer-readable storage medium storing a computer program, wherein the computer program, when executed by a processor, implements the binding method according to claim 8 .

12. A binding method, applied by a receiving node, comprising:
acquiring channel identification information from a network management device, wherein the channel identification information is configured by the network management device according to a multiplexing structure of an optical layer channel; and
binding a local optical layer channel according to the channel identification information, wherein binding the local optical layer channel comprises binding a local channel layer interface and a local subchannel layer interface to generate an interface address at an channel layer and an interface address at an optical tributary signal assembly (OTSiA) layer for creating an optical layer path.

13. A receiving node, comprising:
at least one processor; and
a storage apparatus configured to store at least one program, wherein
when executed by the at least one processor, the at least one program causes the at least one processor to implement the binding method according to claim 12 .

14. The method according to claim 12 , wherein the channel identification information comprises following information of the receiving node:
an optical layer adaptation interface local identifier;
a number of channels contained in an optical layer;
a channel local identifier;
a number of subchannels contained in a channel; and
a subchannel local identifier.

15. A non-transitory computer-readable storage medium storing a computer program, wherein the computer program, when executed by a processor, implements the binding method according to claim 12 .
