Abstract

Exemplary embodiments include methods and systems for monitoring, analyzing, and troubleshooting of control plane dynamics of a network including collecting state data from the one or more routers of one or more protocols at discrete time intervals, the state data being associated with one or more routers of a network, analyzing corresponding state data collected at two or more discrete time intervals, and outputting a result of the analysis of the state data collected from the one or more routers of the network.

Claims

1. A system comprising:

a collector module configured to collect state data of one or more protocols at discrete time intervals, the state data being associated with one or more routers of a network;

an analytical module configured to analyze corresponding state data collected at two or more discrete time intervals; and

a presentation module configured to output a result of the analysis of the state data.

2. The system of claim 1, wherein the one or more routers associated with the network are one or more backbone routers.

3. The system of claim 1, wherein the collector module is further configured to access the one or more routers via at least of a telecommunication network, secure socket header (SSH) and simple network management protocol (SNMP).

4. The system of claim 1, wherein the one or more protocols associated with the one or more routers comprises at least one of internal Border Gateway Protocol (iBGP), Label Distribution Protocol (LDP), Protocol Independent Multicast (PIM), and Open Shortest Path First (OSPF) protocol.

5. The system of claim 1, wherein the collector module is further configured to perform at least one of filter, format and aggregate the state data.

6. The system of claim 1, wherein the analytical module is further configured to perform at least one of pattern matching analysis, time series analysis and forensic analysis based at least in part on the corresponding state data collected at the two or more discrete time intervals.

7. The system of claim 1, wherein the presentation module is further configured to alert a user based at least in part on one or more parameters specified by the user.

8. The system of claim 1, wherein in response to the analytical module determining that at least one of the one or more protocols and one or more interfaces associated with the one or more routers are in a down state, the presentation module is configured to alert a user.

9. The system of claim 1, wherein the presentation module is further configured to generate a report based at least in part on the analysis of the state data collected at two or more discrete time intervals.

10. The system of claim 1, wherein the presentation module is further configured to provide at least one of a separate view and an unified view of the one or more protocols associated with the one or more routers.

11. The system of claim 1, wherein the one or more routers further comprise at least one of outbound interfaces, local interfaces, logical interfaces, inbound interfaces, service interfaces, and client interfaces.

12. The system of claim 1, further comprises one or more user devices to display the result of the analysis.

14. The method of claim 12, further comprises alerting a user based at least in part on a determination that at least one of the one or more protocols and one or more interfaces associated with the one or more routers are in a down state.

13. A method, comprising:

collecting state data of one or more protocols at discrete time intervals, the state data being associated one or more routers of a network;

analyzing corresponding state data collected at two or more discrete time intervals; and

outputting a result of the analysis of the state data.

15. The method of claim 13, wherein the one or more routers associated with the network is located in a control plane of the network.

16. The method of claim 13, further comprises performing at least one of filtering, formatting and aggregating the state data of the one or more protocols collected from the one or more routers associated with the network.

17. The method of claim 13, wherein analyzing the state data of the one or more protocols collected from the one or more routers associated with the network further comprises performing at least one of pattern matching analysis, time series analysis, and forensic analysis based at least in part on the state data of the one or more protocols associated with the one or more routers at the two or more discrete time intervals.

18. The method of claim 13, further comprises alerting a user based at least in part on one or more parameters specified by the user.

19. The method of claim 13, further comprises generating a report based at least in part on one or more parameters specified by a user.

20. The method of claim 13, further comprises providing at least one of a separate view and an unified view of the one or more protocols associated with the one or more routers.

21. A computer readable media comprising code to perform the acts of the method of claim 13.
