Abstract

Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for managing configurations of telecommunications nodes. In one aspect, a system includes a file server; a subtending device coupled to the file server, and a telecommunications node coupled to the subtending device. The subtending device can include one or more line cards that connect one or more telecommunications nodes to a network. The telecommunications device receives, from the file server and based on provisioning information provided by the subtending device, a first configuration file and replaces a wildcard value in the first filename with a unit-specific identifier. A unit-specific configuration file is requested from the file server, and used to configure the node. A change is detected to the configuration, and an updated unit-specific configuration file is posted to the file server using the first filename.

Claims

1. A telecommunications node comprising:

a transceiver that couples the telecommunications node to a line card of a subtending device that provides access to a carrier network;

a memory device; and

a data processor coupled to the transceiver and the memory device, wherein the data processor is configured to perform operations comprising;

receiving, from a file server, a first configuration file for the telecommunications node;

parsing the first configuration file to identify a filename of a unit-specific configuration file for the telecommunications node;

replacing a wildcard value in the filename with a unit-specific identifier to derive a network path of a unit-specific configuration file;

configuring one or more parameters of the telecommunications node based on a given configuration file identified from the first configuration file;

detecting a change to a configuration of the telecommunications node; and

posting, to the derived network path, an updated unit-specific configuration file in response to detecting the change to the configuration.

2. The telecommunications node of claim 1, wherein detecting the change to the configuration comprises detecting a change to the given configuration file used to configure the telecommunications node at start-up of the telecommunications node.

3. The telecommunications node of claim 2, wherein posting the updated unit-specific configuration file comprises:

transmitting the updated configuration file to the file server; and

storing, on a storage device of the file server, the updated configuration file at the derived network path.

4. The telecommunications node of claim 1, wherein the data processor is configured to perform operations further comprising scheduling, in response to detecting the change and by the telecommunications node, the posting of the updated unit-specific configuration file at a time specified by the telecommunications node.

5. The telecommunications node of claim 4, wherein the scheduling is performed by the telecommunications node prior to transmission, by the telecommunications node, of an indication of the change.

6. A system comprising:

a file server;

a subtending device coupled to the file server, wherein the subtending device includes one or more line cards that connect one or more telecommunications nodes to a network; and

a telecommunications node coupled to the subtending device, wherein the telecommunications node manages a configuration of the telecommunications node by performing operations including;

receiving, from the file server and based, at least in part, on provisioning data provided by the subtending device, a first configuration file for the telecommunications node;

parsing the first configuration file to identify a filename of a unit-specific configuration file for the telecommunications node;

replacing a wildcard value in the filename with a unit-specific identifier to derive a network path of a unit-specific configuration file;

configuring one or more parameters of the telecommunications node based on a given configuration file identified from the first configuration file;

detecting a change to a configuration of the telecommunications node; and

posting, to the derived network path, an updated unit-specific configuration file in response to detecting the change to the configuration.

7. The system of claim 6, wherein detecting the change to the configuration comprises detecting a change to the given configuration file used to configure the telecommunications node at start-up of the telecommunications node.

8. The system of claim 7, wherein posting the updated unit-specific configuration file comprises:

transmitting, by the telecommunications node, the updated configuration file to the file server; and

storing, on a storage device of the file server, the updated configuration file at the derived network path.

9. The system of claim 6, wherein the telecommunications node performs operations further comprising scheduling, in response to detecting the change, the posting of the updated unit-specific configuration file at a time specified by the telecommunications node.

10. The system of claim 9, wherein the scheduling is performed by the telecommunications node prior to transmission, by the telecommunications node, of an indication of the change.

11. The system of claim 6, further comprising a replacement telecommunications node that is installed to replace the telecommunications node wherein the replacement telecommunications node performs operations comprising:

after the posting;

obtaining the first configuration file from the file server;

parsing the first configuration file to identify the filename of the unit-specific configuration file;

replacing the wildcard in the filename with the unit-specific identifier to derive the network path of the unit-specific configuration file;

obtaining the unit-specific configuration file from the file server; and

performing an action based on the obtained unit-specific configuration file.

12. The system of claim 11, wherein the replacement telecommunications node performs operations further comprising:

comparing the obtained unit-specific configuration file to a stored configuration file for the replacement telecommunications node, wherein performing an action comprises performing an action based on the comparison, including;

replacing the stored configuration file with the unit-specific configuration file when the unit-specific configuration file does not match the stored configuration file; and

discarding the unit-specific configuration file when the unit-specific configuration file matches the stored configuration file.

13. A method of managing telecommunications node configuration, comprising:

receiving, by a telecommunications node and from a file server, a first configuration file for the telecommunications node;

parsing, by the telecommunications node, the first configuration file to identify a filename of a unit-specific configuration file for the telecommunications node;

replacing, by the telecommunications node, a wildcard value in the filename with a unit-specific identifier to derive a network path of a unit-specific configuration file;

configuring, by the telecommunications node, one or more parameters of the telecommunications node based on a given configuration file identified from the first configuration file;

detecting, by the telecommunications node, a change to a configuration of the telecommunications node; and

posting, by the telecommunications node and to the derived network path, an updated unit-specific configuration file in response to detecting the change to the configuration.

14. The method of claim 13, wherein detecting the change to the configuration comprises detecting a change to the given configuration file used to configure the telecommunications node at start-up of the telecommunications node.

15. The method of claim 14, wherein posting the updated unit-specific configuration file comprises:

transmitting, by the telecommunications node, the updated configuration file to the file server; and

storing, on a storage device of the file server, the updated configuration file at the derived network path.
