Abstract

A method for the management of resources for transmission compliant with a communications protocol, in a communications network, of a first data stream between a source device (101, 102, 103) and at least one sink device (106), is implemented by a manager device and comprises step of a first allocation of a first value of bandwidth, called a reference value, for the transmission of the first stream. Such a method furthermore comprises the following steps: obtaining a piece of information representing a first temporary value of bandwidth for the transmission of the first stream, associated with a relevance time interval; making a second allocation, for a duration equal to the relevance time interval, of a second value, called a validated value, of bandwidth for the transmission of the first stream dependant on the first temporary value of bandwidth for the transmission of the first stream.

Claims

1. A method for managing resources for transmissions compliant with a communications protocol, in a communications network, for transmitting a first data stream between a source device and at least one sink device, said method being implemented by a manager device and comprising steps of:

making a first allocation of a first value, called a reference value, of bandwidth for transmission of the first data stream;

obtaining a piece of information representing a first temporary value of bandwidth for transmission of the first data stream, associated with a relevance time interval;

making a second allocation, for a duration equal to the relevance time interval, of a second value, called a validated value, of bandwidth for transmission of the first data stream dependant on the reference value and the first temporary value of the bandwidth for transmission of the first data stream;

making available, for transmission of the first data stream after expiration of the relevance time interval, an amount of bandwidth equal to at least the reference value.

2. A resource management method according to claim 1, further comprising a step of determining the validated value, wherein, if the first temporary value is lower than the reference value, then the validated value is equal to the first temporary value.

3. A resource management method according to claim 2, wherein a difference between the reference value and the first temporary value is added to a value of bandwidth unutilized in the network during the relevance time interval.

4. A resource management method according to claim 2, wherein, if the first temporary value is greater than the reference value, then the step of determining the validated value includes a step of determining a bandwidth value, called a difference value, equal to a difference between the first temporary value and the reference value.

5. A resource management method according to claim 4, further comprising a step of determining a value of bandwidth unutilized in the network in said relevance time interval.

6. A resource management method according to claim 5, wherein said step of determining a value of bandwidth unutilized in said relevance time interval includes a preliminary step of obtaining at least one piece of information representing at least one second temporary value of bandwidth for transmission of at least one second data stream in said relevance time interval.

7. A resource management method according to claim 5, wherein said step of determining the validated value is performed according to a policy of redistribution of said value of bandwidth unutilized in the network in said relevance time interval, said policy taking account of a value of classification associated with each stream being transmitted in the network.

8. A resource management method according to claim 7, wherein, for a given stream, said value of classification is obtained from at least one piece of information representing a difference between the reference value and at least one validated value, for a given time interval, of bandwidth for transmission of said given stream.

9. A resource management method according to claim 8, wherein said value of classification of the given stream is increased when the first temporary value is greater than the reference value for transmission of said given stream.

10. A resource management method according to claim 6, wherein, for a given stream, a value of classification is obtained from at least one piece of information representing a difference between the reference value and at least one validated value, for a given time interval, of bandwidth for transmission of said given stream.

11. A resource management method according to claim 8, wherein said value of classification of said given stream is reduced when the first temporary value is less than the reference value for transmission of said given stream.

12. A resource management method according to claim 7, wherein the validated value is equal to the first temporary value, if the difference value is less than said value of bandwidth unutilized in the network in said relevance time interval, that is remaining once each stream undergoing transmission in the network, whose value of classification is greater than that of the first data stream, has been taken into account in a step of redistributing said value of bandwidth unutilized in the network in said relevance time interval.

13. A resource management method according to claim 1, wherein said piece of information representing the first temporary value of bandwidth is computed by the manager device according to a piece of information representing a predicted value of bandwidth, said piece of information representing a predicted value of bandwidth being transmitted to the manager device by the source device.

14. A resource management method according to claim 1, wherein said piece of information representing the first temporary value of bandwidth is computed by the source device according to a piece of information representing a predicted value of bandwidth, and then said piece of information representing the first temporary value of bandwidth is transmitted to the manager device.

15. A resource management method according to claim 2, wherein the reference value depends on a level of transmission priority associated with said first data stream.

16. A resource management method according to claim 1, wherein the communications protocol is an IEEE 802.11e protocol, the manager device is a QAP terminal, and the source device is a QSTA terminal.

17. A computer-readable storage medium storing a set of instructions that, when executed by a computer, implements a method for managing resources for transmissions compliant with a communications protocol, in a communications network, for transmitting a first data stream between a source device and at least one sink device, wherein said method includes steps of:

making a first allocation of a first value, called a reference value, of bandwidth affected by transmission of the first data stream;

obtaining a piece of information representing a first temporary value of bandwidth for transmission of the first data stream, associated with a relevance time interval;

making a second allocation, for a duration equal to the relevance time interval, of a second value, called a validated value, of bandwidth for transmission of the first data stream dependant on the reference value and the first temporary value of bandwidth for transmission of the first data stream;

making available, for transmission of the first data stream after expiration of the relevance time interval, an amount of bandwidth equal to at least the reference value.

18. A manager device comprising managing means for managing resources for transmissions compliant with a communications protocol, in a communications network, for transmitting a first data stream between a source device and at least one sink device, said managing means including:

first means for allocating a first value, called a reference value, of bandwidth affected by transmission of the first data stream;

means for obtaining a piece of information representing a first temporary value of bandwidth for transmission of the first data stream, associated with a relevance time interval;
