Abstract

A system for controlling the bandwidth allocated to a network connection between two nodes. The system receives a bandwidth change request, and generates and sends control commands to network switches of the connection in order to satisfy the change request. A bandwidth control interface, available over the Internet, has code for generating a display of bandwidths available for selection; code for receiving a bandwidth selection chosen from the bandwidths; and code for sending the change request to the network to adjust the bandwidth on the basis of the selection. The interface provides a bandwidth dial representation of the bandwidths that can be selected.

Claims

1. A system for controlling the bandwidth allocated to a network connection between two nodes and having a plurality of network elements located between the two nodes, comprising:

a user interface for generating and sending, in response to a user selection, a dynamic bandwidth change request for said bandwidth allocated to said network connection;

a server for sending program code for said user interface over a communications network for generation of a display of said interface on a remote computer system of said user, and for receiving said bandwidth change request; and

a network control system in communication with said server, for generating control commands to dynamically control the configuration of the plurality of network elements in order to satisfy said dynamic bandwidth change request and sending said commands to said network elements.

2. A system as claimed in claim 1, wherein said interface is a graphical user interface including controls for selecting a value of said bandwidth, said value being included in said bandwidth change request.

3. A system as claimed in claim 2, wherein said graphical user interface includes controls for selecting one of a plurality of bandwidth ranges, and controls for selecting one of a plurality of bandwidth values falling within the currently selected range.

4. A system as claimed in claim 1, wherein said interface includes a dynamic graphical user interface.

5. A system as claimed in claim 1, including means for determining the network addresses of said plurality of network elements whose configurations must be changed to satisfy said change request.

6. A system as claimed in claim 1, including means for receiving and analysing responses from said network elements, and in response thereto, sending messages to confirm said change request has been satisfied.

7. A system as claimed in claim 1, including receiving and analysing responses from said network elements, and generating and sending at least one charging record in response thereto.

8. A system as claimed in claim 7, including generating billing data in response to receipt of said charging record.

9. A system as claimed in claim 1, including generating and sending an electronic message to at least one of the two nodes to confirm said change of request has been satisfied.

10. A system as claimed in claim 1, including means for storing the time of configuration changes of said network elements, and for denying said change request if an elapsed time since the time of a previous configuration change is less than a pre-determined value.

11. A system as claimed in any one of the preceding claims, wherein said network elements are packet switches.

12. A method of controlling bandwidth allocated to a network connection between two nodes and having a plurality of network elements located between the two nodes, comprising:

receiving a dynamic bandwidth change request for said bandwidth allocated to said network connection from a graphical user interface of a remote computer system over a communications network, the user interface configured to receive a user selection and generate said request in response;

identifying two or more of the plurality of network elements located between the two nodes requiring a configuration change to satisfy said change request; and

dynamically generating and sending a configuration change command to said two or more identified network elements.

13. A method as claimed in claim 12, including receiving a response from said elements and sending a message to confirm said configuration change in response thereto.

14. A method as claimed in claim 13, including generating and sending a charging record corresponding to said configuration change for use in generating billing data.

15. A method as claimed in claim 12, including sending said graphical user interface to said remote computer system over said communications network for display to said user.

16. A method as claimed in claim 15, wherein said user interface is displayed by a browser on said remote computer system.

17. A method as claimed in claim 16, wherein said interface provides a representation of a bandwidth dial including controls for making said selection.
