Abstract

A system for monitoring a communications network generates a total value figure, using a store of value information. The system can identify which of the monitored flows of traffic rely on a given one or more of the components of the network, and generate a total value of all the identified flows. This type of value information can be easier for network operators to interpret because the information is more direct, and more explicit. Also, many specific rules/warnings about reconfigurations need not be provided. Values can be sent to remote field workers, or used for network configuration, network planning, and financial reporting.

Claims

1. A system for monitoring a communications network, comprising many components, and being arranged for carrying many flows of telecommunications traffic, having different financial values for an operator of the communications network, the system being coupled to receive information from the components about to monitor the flows in the network, and having being coupled to a store of value information based on one or more service level agreements relating to at least some of the flows, the value information indicating one or both of a positive revenue from the successful operation of the flow, and a negative revenue if the flow is degraded, the system further comprising:

a flow identifier part for using the information about the flows in the network to determine and output an indication of identifying which of the monitored flows of traffic rely on a given one or more of the components, and

a valuer part arranged to receive the indication of which of the monitored flows of traffic rely on the given one or more of the components, and arranged to use that indication to retrieve corresponding value information for the indicated flows from the store, and to use that corresponding value information to determine a total value of the indicated identified flows from the store of value information relating to the identified flows.

2. The system of claim 1, being coupled to a display and being arranged to display the total value on the display.

3. The system of claim 2, having an interface arranged to receive a request identifying the given or more components and arranged to send the total value to a remote terminal for display.

4. The system of claim 2, having an interface for coupling to a centralized network reconfiguration system, the display being on an operator terminal of the reconfiguration system.

5. The system of claim 1, having an interface for coupling to a centralized network reconfiguration system to enable reconfiguration of the given one or more components only if the total value does not exceed a pre-determined threshold.

6. The system of claim 1, further having a value map generator arranged to determine the total values for many of the components, to create a value map of part or all of the network.

7. The system of claim 1, the network being a wide area optical wavelength division multiplexed transport network.

8. The system of claim 1, having an adjuster arranged to adjust the total value by determining determine if the identified indicated flows have protection paths not relying on the given one or more components, and if any of the flows rely on the given one or more components not for transmission but only for a protection path, and adjusting to adjust the total value accordingly to these determinations.

9. The system of claim 1, having an adjuster arranged to determine an adjusted total value taking into account how long the given component could be degraded.

10. The system of claim 1, having an accuracy determiner arranged to determine a level of accuracy of the total value.

11. The system of claim 1, the flow identifier part and the valuer part being implemented in the form of software on a computer readable medium.

13. A system for determining a cost benefit ratio of a given component of a communications network, the system comprising the monitoring system of claim 1, and the system further being arranged to receive from the monitoring system a number of total values determined at different points in time for the given component and having an averager arranged to determine an average of the total value for the given component over a predetermined period of time, and to use the average, and a cost of the given component to determine the cost benefit ratio for the given component a ratio determiner arranged to combine the average with a component cost.

14. A system for alerting a craftsperson at a remote location of information relating to traffic flows currently flowing through or relying on a given component of a communications network, the system comprising:

The monitoring system of claim 1,

a component identifier arranged to send information identifying the given component to the a monitoring system as set out in claim 1, and

a value sender arranged to send the total value for the given component, generated by the monitoring system, to the remote terminal for use by the craftsperson.

15. The system of claim 14, further having an arrangement for automated entry of the information identifying the given component.

12. A method of monitoring a communications network, the network being made up of many components, and arranged for carrying many flows of telecommunications traffic having different financial values, the system being coupled to the components to monitor the flows in the network, and having a store of value information based on one or more service level agreements relating to at least some of the flows, the value information indicating one or both of a positive revenue from the successful operation of the flow, and a negative revenue if the flow is degraded, the method having the steps of:

determing identifying which of the flows of traffic rely on a given one or more of the components, and

retrieving from the store corresponding value information for these flows and determining from the corresponding value information a total value of these the identified flows from the store of value information relating to the identified flows.

16. A system for monitoring a communications network, comprising many components, and being arranged for carrying many flows of telecommunications traffic, having difterent financial values for an operator of the network, the system being coupled to receive information from the components to monitor the flows in the network, and having being coupled to a store of value information based on one or more service level agreements relating to at least some of the flows, the value information indicating one or both of a positive revenue from the successful operation of the flow, and a negative revenue if the flow is degraded, the system further comprimising:

means for identifying which of the monitored flows of traffic rely on a given one or more of the components and outputting an indication of these flows, and

means for using the indication to retrieve corresponding value information for these flows from the store, and to use that corresponding value information to determine determining a total value of the indicated identified flows from the store of value information relating to the identified flows.
