Abstract

A system for communication network management of a utility grid includes a database configured to store a grid information data set, where the grid information data set includes network device information for the utility grid and a network management system executable by a processor to: receive an event message from one or more network devices indicative of one or more failures in a communication network of the utility grid; retrieve the grid information data set; identify one or more network device associated with the one or more failures based on the grid information data set; transmit a request for a response to the identified one or more network devices; determine a response pattern based on responses from the identified one or more network devices in order to identify a cause of the failure based on the response pattern.

retrieve the grid information data set;

identify one or more network devices associated with the communication failure based on the grid information data set, the one or more network devices being in communication with the network device that transmitted the event message;

transmit a request for a response to the identified one or more network devices; and

determine a response pattern based on responses from the identified one or more network devices; and

a fault, performance, and configuration management (FPCM) module executable by the processor to communicate directly with at least one of the identified network devices, and to determine a cause of the communication failure based on the response patterns and event messages from respective network devices.

2. The system of claim 1, where the system for communication network management is further executable to:

test connectivity between the identified network devices; and

identify a cause of the communication failure based on the connectivity test.

3. The system of claim 1, where the system for communication network management is further executable to:

determine a network device corresponding to the event message; and

identify the cause of the communication failure as a malfunction in the network device.

4. The system of claim 1, where the event message comprises a plurality of event messages, the system further comprising:

an incident management module executable by the processor to generate a single trouble ticket associated with a single network device, in response to a plurality of causes of failure identified for the communication failure.

5. The system of claim 1, further comprising:

a service level management module executable by the processor to report penalties that ensure accounting of owned service credits beyond contractual usage levels and to provide power against contractual service level obligations.

6. The system of claim 1, where the system for communication network management is further executable to:

identify a different network device based on the response pattern;

transmit a request for a response to the different network device; and

identify the cause of the communication failure based on the response from the different network device.

7. The system of claim 1, where the cause of the communication failure is determined based on a comparison of the response pattern with a predetermined response pattern stored in the database.

8. A method for managing a communication network of a utility grid, the method executable by a computer coupled with a processor and memory of an integrated network operations and management system, the method comprising:

facilitating, by the processor, direct communication with a plurality of network devices via the communication network of the utility grid that facilitates direct communication with respective network devices, the network devices configured to monitor electrical equipment included in the utility grid;

receiving, with the processor, an event message from a network device, the event message indicative of a communication failure in the communication network of the utility grid;

retrieving, with the processor, a grid information data set from a database, where the grid information data set includes network device information for the utility grid;
