| 摘要 |
The invention in particular concerns a method and a device for estimating a level of use of a communication network linking a server and at least one client, said communication network being used to transmit a data stream at a transmission rate corresponding to the temporal frequency of said data stream, said data stream comprising at least one item of information characterizing a theoretical rate dependent on said transmission rate of said data stream. After having obtained (121) said theoretical rate of said data stream, the real reception rate of at least one part of said data stream is evaluated (109). Said theoretical rate and said evaluated rate are then compared (113) to estimate said level of use of said communication network. The level of subscription of a client to multicast sessions may be adapted according to the level of use of the communication network. |
