Abstract

A method of setting up a communication between a plurality of terminals (T1, . . . , Tn) in a network comprises the activation of at least one chosen node (N1, . . . , Nm) of the network. A node is selected beforehand as a function of predetermined criteria, then the presence of possible means of management of communication on this node (N1, . . . , Nm) is thereafter detected. In case of absence of the means of management on the node, means of management of communication are dispatched to the node. This method applies in particular to computer networks that can support teleconferences.

Claims

1. A method of setting up a data communication between a plurality of terminals connected to a network comprising a plurality of network nodes, in which at least one chosen node of the network sets up a communication between the terminals,

in which at least some of the nodes are configurable nodes, the method comprising the following steps:

a) selection of at least one configurable node of the network as a function of predetermined criteria;

b) detection of the presence of possible means of management of communication on this node; and

c) dispatching of means of management of communication to said node in case of detected absence of the means of management of communication on the node in step b).

2. The method according to claim 1, in which said at least one configurable node of the network is selected as a function of criteria predetermined from among at least a topology of the network, a proximity of the terminals, a state of the bandwidth of the network in the neighborhood of the node, an available workload of said node and/or a compromise between these criteria.

3. The method according to claim 1, in which a single configurable node sets up the communication between said terminals.

4. The method according to claim 1, in which a plurality of configurable nodes set up the communication between said terminals.

5. The method according to claim 4, in which during step (a), each node selected is allocated to at least one terminal to set up a communication between said one terminal allocated and the other nodes.

6. The method according to claim 1, in which, in the course of step (b), one determines whether an update of the means of management of communication is necessary, and in which the corresponding update is dispatched during step (c).

7. The method according to claim 1, in which the communication management means dispatched in the course of step (c) are adapted for performing an operation from among at least a data redirection, a data composition, a data compression, a data decompression, a change of format, a mixing, a multiplexing and/or a combination of these operations.

8. The method according to claim 1, in which, once the communication has been set up:

d) at least one characteristic of said configurable node is monitored;

e) at least one new configurable node is chosen if the value of at least one characteristic monitored in the course of step (d) lies in a predetermined span of values.

9. The method according to claim 8, in which the characteristic monitored comprises at least one parameter from among a workload of the node, a bandwidth of the network, a request to set up new communications, and/or a compromise between these parameters.

10. The method according to claim 1, in which the communication is set up for a teleconference between the terminals of a network.

11. A module intervening in the setting up of a communication between a plurality of terminals connected to a network comprising a plurality of network nodes, said module being connected to said network and comprising means for configuring in such a way as to render active at least one chosen node of the network so as to set up a communication between the terminals, said module comprising:

means of selection of at least one configurable node of the network so as to select a node as a function of predetermined criteria, at least some of the nodes of the network being configurable;

configuration detection means adapted for detecting the presence of means of management of communication on the node selected;

means of uploading for dispatching means of management of communication to said node in case of absence of the means of management of communication, detected by said configuration detection means.

12. The module according to claim 11, wherein it is installed in a multipoint controller.

13. A computer program product intended to be stored in a memory of a module capable of setting up a communication between a plurality of terminals connected to a network comprising a plurality of network nodes, the computer program product comprising instructions for:

a) selecting at least one node of the network as a function of predetermined criteria, at least some of the nodes of the network being configurable;

b) determining a configuration of said node by detecting the presence of possible means of management of communication on this node; and

c) dispatching means of management of communication to said node in case of detected absence of the means of management of communication on the node during the execution of instruction b).
