1995 And devices for the estimation of a level of use of a communication network and a level of subscriptions to multipoint groups

摘要

A particular subject of the invention is a method and a device for estimating a level of the use of a communication network that connects a server and at least a customer, said communication network is used for transmitting a data stream at a rate of transmission corresponding to the temporal frequency of the said stream of data, the stream of data comprising at least one information characterizing a theoretical flow rate depending on the transmission rate of flow of data. After having obtained (121), said theoretical flow rate of flow of data, the real flow rate of the reception of at least a portion of the data stream is evaluated (109). The theoretical flow rate and the flow rate measured are then compared (113) in order to estimate the level of the use of said communication network. The level of subscriptions from a client to multipoint groups can be adapted according to the level of use of the communication network.
