Abstract

A dynamic bandwidth manager for determining the bandwidth available to an IP connected client device, the IP connected client device requesting access to multimedia resources from a service provider, the dynamic bandwidth manager comprising: a receiving component for receiving an IP address of an IP connected client requesting access to a resource; a requesting component for locating a nearest managed device to the IP connected client and requesting a current network management data set pertaining to the IP connected client from the located managed device; a calculation component for retrieving a previously stored set of network management data pertaining to the IP connected client and for analysing the network management data sets, in dependence on the current network management data set and the previously stored network management data sets, to calculate the available bandwidth capacity of the IP connected client.

Claims

1. A dynamic bandwidth manager comprising:

a receiving component for receiving an Internet Protocol (IP) address of an IP connected client requesting access to a multimedia resource from a service provider;

a requesting component for locating a nearest managed device to the IP connected client and requesting a current network management data set pertaining to the IP connected client from the located managed device; and

a calculation component for retrieving a previously stored network management data set pertaining to the IP connected client and for analysing the current and previously stored network management data sets to calculate an available bandwidth capacity of the IP connected client based on an amount of total bandwidth specific to the client that is allotted to the client for use at any one time.

2. The dynamic bandwidth manager of claim 1, wherein the requesting component sends a request to a Simple Network Management Protocol (SNMP) agent located at the nearest managed device for requesting network management data located in a management information database.

3. The dynamic bandwidth manager of claim 1, wherein the current and previously stored network management data sets comprise a number of octets received and transmitted by the IP address over a given time period.

4. The dynamic bandwidth manager of claim 1, wherein the requestor component further comprises a limiter for determining a relevance of the previously stored network management data set.

5. The dynamic bandwidth manager of claim 1, wherein the dynamic bandwidth manager communicates with a transcoding component that adapts data content for the multimedia resource to fit the available bandwidth capacity for the IP connected client.

6. The dynamic bandwidth manager of claim 1, wherein the available bandwidth capacity is further based on a subscription for the IP connected client.

7. A method of managing an available bandwidth capacity for an Internet Protocol (IP) connected client, the method comprising:

receiving, by a computer device, an IP address of the IP connected client;

locating, by the computer device, a nearest managed device to the IP connected client;

requesting, by the computer device, a current network management data set pertaining to the IP connected client from the located managed device;

retrieving, by the computer device, a previously stored network management data set pertaining to the IP connected client; and

analysing, by the computer device, the current and previously stored network management data sets to calculate the available bandwidth capacity of the IP connected client based on an amount of total bandwidth specific to the client that is allotted to the client for use at any one time.

8. The method of claim 7, wherein the requesting includes transmitting a request to a Simple Network Management Protocol (SNMP) agent located at the nearest managed device for requesting network management data located in a management information database.

9. The method of claim 7, wherein the requesting includes determining a relevance of the previously stored network management data set.

10. The method of claim 7, wherein the receiving includes:

receiving an access request for a multimedia service from the IP connected client; and

obtaining the IP address from the access request.

11. The method of claim 10, further comprising communicating the available bandwidth capacity to a transcoding component for providing data content for the multimedia service.

12. The method of claim 10, further comprising adapting data content for the multimedia service based on the available bandwidth capacity.

13. A computer program stored on a non-transitory computer-readable storage medium, which when executed by a computer system enables the computer system to manage an available bandwidth capacity for an Internet Protocol (IP) connected client, the computer program comprising instructions that enable the computer system to:

receive an IP address of the IP connected client;

locate a nearest managed device to the IP connected client;

request a current network management data set pertaining to the IP connected client from the located managed device;

retrieve a previously stored network management data set pertaining to the IP connected client; and

analyse the current and previously stored network management data sets to calculate the available bandwidth capacity of the IP connected client based on an amount of total bandwidth specific to the client that is allotted to the client for use at any one time.

14. The computer program of claim 13, wherein the instructions that enable the computer system to request enable the computer system to transmit a request to a Simple Network Management Protocol (SNMP) agent located at the nearest managed device for requesting network management data located in a management information database.

15. The computer program of claim 13, wherein the instructions that enable the computer system to request enable the computer system to determine a relevance of the previously stored network management data set.

16. The computer program of claim 13, wherein the instructions that enable the computer system to receive enable the computer system to:

receive an access request for a multimedia service from the IP connected client; and

obtain the IP address from the access request.

17. The computer program of claim 16, further comprising instructions that enable the computer system to communicate the available bandwidth capacity to a transcoding component for providing data content for the multimedia service.

18. The computer program of claim 16, further comprising adapting data content for the multimedia service based on the available bandwidth capacity.

19. At least one computer device that provides a service for providing multimedia data content, the service performing a method comprising:

receiving a request for a multimedia service;

determining an Internet Protocol (IP) address of a requesting IP connected client from the request;

locating a managed device nearest to the IP connected client;

requesting a current network management data set pertaining to the IP address from the managed device;

retrieving a previously stored network management data set pertaining to the IP address; and

analysing the current and previously stored network management data sets to calculate an available bandwidth capacity of the IP connected client based on an amount of total bandwidth specific to the client that is allotted to the client for use at any one time.

20. The at least one computer device that provided the service for providing multimedia data content of claim 19, the method further comprising transcoding data content for the multimedia service to adapt the data content to the available bandwidth capacity.
