Abstract

A cable media converter (CMC) management method, including receiving, by a CMC controller by using a management channel, a second message packet sent by a CMC, where the second message packet has an identifier of the CMC and configuration file information of a cable modem (CM), and where the identifier of the CMC uniquely identifies the CMC, and determining, by the CMC controller according to a locally saved correspondence between an optical line terminal (OLT) and a CMC, an OLT corresponding to the CMC identified by the identifier in the second message packet, and sending the configuration file information in the second message packet to the determined OLT.

First claim

What is claimed is:

1. A method, comprising:
receiving, by a cable media converter (CMC) controller using a management channel, a second message packet sent by a CMC, wherein the second message packet comprises an identifier of the CMC and configuration file information of a cable modem (CM), and wherein the identifier of the CMC uniquely identifies the CMC; and
determining, by the CMC controller according to a locally saved correspondence between an optical line terminal (OLT) and the CMC, the OLT corresponding to the CMC identified by the identifier of the CMC in the second message packet;
sending, by the CMC controller, the configuration file information of the CM in the second message packet to the determined OLT; and
obtaining, by the CMC controller in advance from each of a plurality of OLTs that are connected to the CMC controller, information about a corresponding CMC connected to the each of the plurality of OLTs, to form a correspondence between the corresponding CMC and the each of the plurality of OLTs.

2. The method according to claim 1 , wherein the OLT is in a one-to-one correspondence with the CMC, and the CMC controller is connected to the plurality of OLTs.

3. The method according to claim 1 , wherein the configuration file information of the CM is received by the CMC from a first message packet sent by the CM.

4. The method according to claim 1 , wherein the identifier of the CMC is added by the CMC to the configuration file information of the CM before the second message packet is received by the CMC controller.

5. The method of claim 1 , wherein the configuration file information of the CM comprises information of a parameter when the CM comes online.

6. The method according to claim 1 , wherein the determined OLT performs adaptive configuration after the determined OLT receives the configuration file information.

7. A cable media converter (CMC) controller, comprising:
at least one processor;
a transmitter;
a receiver; and
a non-transitory computer readable storage medium storing processor-executable program to be executed by the at least one processor, the processor-executable program including instructions for:
receiving a second message packet sent by a CMC using a management channel, wherein the second message packet comprises an identifier of the CMC and configuration file information of a cable modem (CM), and the identifier of the CMC uniquely identifies the CMC;
determining, according to a locally saved correspondence between an optical line terminal (OLT) and the CMC, the OLT corresponding to the CMC identified by the identifier of the CMC in the second message packet;
sending the configuration file information of the CM in the second message packet to the determined OLT; and
obtaining in advance from each of a plurality of OLTs connected to the CMC controller, information about a corresponding CMC connected to the each of the plurality of OLTs, to form a correspondence between the corresponding CMC and the each of the plurality of OLTs.

8. The CMC controller according to claim 7 , wherein the OLT is in a one-to-one correspondence with the CMC, and the CMC controller is connected to the plurality of OLTs.

9. The CMC controller according to claim 7 , wherein the configuration file information of the CM is received by the CMC from a first message packet sent by the CM.

10. The CMC controller according to claim 7 , wherein the identifier of the CMC is added by the CMC to the configuration file information of the CM before the second message packet is received by the CMC controller.

11. The CMC controller of claim 7 , wherein the configuration file information of the CM comprises information of a parameter when the CM comes online.

12. The CMC controller according to claim 7 , wherein the determined OLT performs adaptive configuration after the determined OLT receives the configuration file information.

13. A cable network system, comprising:
a plurality of optical line terminals (OLTs);
a plurality of cable media converters (CMCs);
a plurality of cable modems (CMs); and
a CMC controller;
wherein each OLT of the plurality of OLTs is connected to a corresponding CMC of the plurality of CMCs by an optical fiber, wherein each CMC of the plurality of CMCs is connected to a corresponding CM by using a cable, and wherein the CMC controller is connected to the plurality of OLT; and
wherein the CMC controller is configured to:
receive a second message packet sent by a CMC of the plurality of cable media converters (CMCs) using a management channel, wherein the second message packet comprises an identifier of the CMC and configuration file information of a CM of the plurality of CMs, and the identifier of the CMC uniquely identifies the CMC;
determine, according to a locally saved correspondence between an OLT of the plurality of OLTs and the CMC, the OLT corresponding to the CMC identified by the identifier of the CMC in the second message packet;
send the configuration file information of the CM in the second message packet to the determined OLT; and
obtain in advance from the each of the plurality of OLTs connected to the CMC controller, information about the corresponding CMC connected to the each of the plurality of OLTs, to form a correspondence between the corresponding CMC and the each of the plurality of OLTs.

14. The cable network system according to claim 13 , wherein the OLT is in a one-to-one correspondence with the CMC, and the CMC controller is connected to the plurality of OLTs.

15. The CMC controller according to claim 13 , wherein the configuration file information of the CM is received by the CMC from a first message packet sent by the CM.

16. The CMC controller according to claim 13 , wherein the identifier of the CMC is added by the CMC to the configuration file information of the CM before the second message packet is received by the CMC controller.

17. The CMC controller of claim 13 , wherein the configuration file information of the CM comprises information of a parameter when the CM comes online.
