Abstract

A method of monitoring network elements in a communications network includes querying the network elements for reboot and/or reconfiguration event data, identifying a group of the network elements responsive to the querying, and updating information for the identified group of network elements in a network configuration database. The method may further include extracting information from the identified group of network elements into independently searchable databases. The invention may be embodied as methods, data processing systems and computer program products.

Claims

1. A method of monitoring a plurality of network elements in a communications network, the method comprising:

querying the plurality of network elements, in parallel, for respective reboot and/or reconfiguration event data, wherein the respective reboot and/or reconfiguration event data indicates a reboot and/or reconfiguration of a corresponding one of the plurality of network elements independent of information from a prior query;

identifying a group of network elements including ones of the plurality of network elements based on the reboot and/or reconfiguration event data received responsive to the parallel querying, wherein the group comprises less than the plurality of network elements;

in response to identifying the group of network elements querying the identified group of network elements, in series, and selectively requesting configuration information from ones of the identified group of network elements, wherein the configuration information is different from the reboot and/or reconfiguration event data;

updating a network configuration database with the configuration information for the ones of the identified group of network elements;

extracting information from the configuration information for the ones of the identified group of network elements; and

storing the extracted information into independently searchable databases according to a category of the configuration information corresponding thereto, wherein each of the independently searchable databases comprises configuration information of a different category for the ones of the identified group of network elements.

2. The method of claim 1, wherein the independently searchable databases respectively include interface information, inventory information, routing information, IP address information, customer information, and configuration assurance information.

3. The method of claim 1, wherein querying the network elements for the respective reboot and/or reconfiguration event data comprises querying the network elements for respective reboot and/or reconfiguration timestamps, wherein the respective reboot and/or reconfiguration timestamps indicate when the reboot and/or reconfiguration of respective ones of the network elements occurred.

4. The method of claim 3, wherein the respective reboot and/or reconfiguration timestamps indicate when a most recent reboot and/or reconfiguration of the respective ones of the network elements occurred, and wherein identifying the group comprises:

comparing the respective reboot and/or reconfiguration timestamps to respective prior timestamps for the respective ones of the network elements; and

compiling a list including the ones of the plurality of network elements for which the respective reboot and/or reconfiguration timestamps do not match the respective prior timestamps,

wherein the respective prior timestamps indicate a reboot and/or reconfiguration of the respective ones of the network elements that occurred prior to the most recent reboot and/or reconfiguration thereof, and wherein the prior timestamps are stored in a temporary database.

5. The method of claim 1, wherein the steps of querying, identifying, requesting, and updating are repetitively performed to generate an archival network configuration database including a configuration history.

6. The method of claim 5, further comprising:

querying the archival network configuration database; and

generating a configuration comparison report between specified times for a network element responsive to a user request.

7. The method of claim 1, further comprising displaying all customers connected to a particular network element responsive to a user request.

8. The method of claim 1, further comprising:

querying the network for added and/or removed network elements; and

updating the network configuration database with information for the added and/or removed elements.

9. A data processing system, comprising:

a network configuration database embodied in a non-transitory computer readable medium; and

a change monitor embodied in a non-transitory computer readable medium configured to query a plurality of network elements in a communication network in parallel for respective reboot and/or reconfiguration event data indicating a reboot and/or reconfiguration of a corresponding one of the plurality of network elements, identify a group of network elements including ones of the plurality of network elements based on the reboot and/or reconfiguration event data received responsive to the parallel queries, wherein the group comprises less than the plurality of network elements, query the identified group of network elements in series and selectively request configuration information from ones of the identified group of network elements in response to identification the group of network elements, wherein the configuration information is different from the reboot and/or reconfiguration event data, update the network configuration database with the configuration information for the ones of the identified group of network elements, extract information from the configuration information for the ones of the identified group of network elements, and store the extracted information into independently searchable databases according to a category of the configuration information corresponding thereto, wherein each of the independently searchable database comprises configuration information of a different category for the ones of the identified group of network elements.

10. The system of claim 9, wherein the independently searchable databases respectively include interface information, inventory information, routing information, IP address information, customer information, and configuration assurance information.

11. The system of claim 9, wherein the change monitor is configured to query the network elements for respective reboot and/or reconfiguration timestamps, wherein the respective reboot and/or reconfiguration timestamps indicate when the reboot and/or reconfiguration of respective ones of the network elements occurred.

12. The system of claim 11, wherein the respective reboot and/or reconfiguration timestamps indicate when a most recent reboot and/or reconfiguration of the respective ones of the network elements occurred, wherein the change monitor is configured to identify the group by comparing the respective reboot and/or reconfiguration timestamps to respective prior timestamps for the respective ones of the network elements and compiling a list including the ones of the plurality of network elements for which the respective reboot and/or reconfiguration timestamps do not match the respective prior timestamps, wherein the respective prior timestamps indicate a reboot and/or reconfiguration of the respective ones of the network elements that occurred prior to the most recent reboot and/or reconfiguration thereof, and wherein the prior timestamps are stored in a temporary database.

13. The system of claim 9, wherein the change monitor is configured to repetitively perform the steps of querying, identifying, requesting, and updating to generate an archival network configuration database including a configuration history.

14. The system of claim 13, wherein the change monitor is further configured to query the archival network configuration database and generate a configuration comparison report between specified times for a network element responsive to a user request.

15. The system of claim 9, further comprising a user interface configured to display all customers connected to a particular network element responsive to a user request.

16. The system of claim 9, wherein the change monitor is further configured to query the network for added and/or removed network elements and to update the network configuration database with information for the added and/or removed elements.
