Abstract

A computer implemented method includes collecting information from multiple network devices regarding utilization over a predetermined period of time. Unused device resources are identified, along with device resources that may be consolidated. Such identifications are provided to a user for use in consolidating the network to reduce power consumption.

Claims

1. A computer implemented method comprising:

collecting in a computer storage medium information from multiple network devices regarding utilization over a predetermined period of time;

identifying using a computer processor unused device resources;

identifying using the computer processor device resources that may be consolidated by grouping boards by technology type and counting ports that are unavailable or available and determining whether ports may be consolidated to boards on a same device or to a different device; and

providing such identifications to a user via an output device for use in consolidating the network to reduce power consumption;

wherein consolidating the device resources comprises identifying how to transfer utilization from one device to another to reduce power consumption of the network.

2. The method of claim 1 wherein the information includes port information, board information, power supply information, routing tables and switching tables.

3. The method of claim 2 wherein unused ports are identified by zero throughput or a status of off for the predetermined period of time.

4. The method of claim 1 wherein consolidating the network comprises identifying network devices that can be turned off.

5. The method of claim 1 wherein consolidating the network comprises identifying devices to consolidate to other devices in order of greatest power consumed.

6. The method of claim 1 and further comprising identifying devices for swapping out with more efficient devices to reduce power consumption of the network.

7. The method of claim 1 wherein consolidating the network comprises mapping ports on multiple boards in a device and identifying ports for consolidation to other boards.

8. The method of claim 1 wherein identifying unused device resources comprises checking if a port is physically connected with a status of down, or configured off, or if port throughput increased over the predetermined period of time.

9. A computer implemented method comprising:

collecting in a computer storage medium information from multiple network devices regarding utilization over a predetermined period of time;

identifying using a computer processor unused device resources;

identifying using the computer processor device resources that may be consolidated by grouping boards by technology type and counting ports that are unavailable or available and determining whether ports may be consolidated to boards on a same device or to a different device;

identifying using the computer processor an efficient device that may be exchanged for existing devices by ensuring that the efficient device supports existing device port types at the same speed;

providing such identifications to a user via an output device for use in consolidating the network to reduce power consumption.

10. The method of claim 9 wherein the collected information includes map routes and switch information from router devices and switch devices.

11. The method of claim 9 wherein the information includes port information, board information, power supply information, routing tables and switching tables.

12. The method of claim 11 wherein unused ports are identified by zero throughput or a status of off for the predetermined period of time.

13. The method of claim 9 wherein consolidating the network comprises identifying network devices that can be turned off.

14. The method of claim 9 wherein consolidating the network comprises identifying how to transfer utilization from one device to another to reduce power consumption of the network.

15. The method of claim 9 wherein consolidating the network comprises identifying devices to consolidate to other devices in order of greatest power consumed.

16. The method of claim 9 and further comprising identifying devices for swapping out with more efficient devices to reduce power consumption of the network.

17. The method of claim 9 wherein consolidating the network comprises mapping ports on multiple boards in a device and identifying ports for consolidation to other boards.

18. The method of claim 9 wherein identifying unused device resources comprises checking if a port is physically connected with a status of down, or configured off, or if port throughput increased over the predetermined period of time.

19. A tangible non-transitory computer readable medium having instructions stored thereon for execution by a computer to perform a method comprising:

collecting information from multiple network devices regarding utilization over a predetermined period of time;

identifying unused device resources;

identifying device resources that may be consolidated by grouping boards by technology type and counting ports that are unavailable or available and determining whether ports may be consolidated to boards on a same device or to a different device; and

providing such identifications to a user via an output device for use in consolidating the network to reduce power consumption;

wherein consolidating the device resources comprises identifying how to transfer utilization from one device to another to reduce power consumption of the network.
