Abstract: The invention concerns a protocol for remote launching of a software application and reserving network resources with quality of service between a caller terminal TA and a called terminal TB. Said protocol consists in: transmitting (A) from the caller terminal to the called terminal TB a reservation request for connection via a server and a transmission via an unconnected network and in establishing (B) between the caller terminal TA and the called terminal TB, a procedure for reserving network resources with quality of service by exchange of messages by transmission via the unconnected network. When the network resources reservation is accepted by the server, a connected network between the caller terminal and the called terminal is established (C) on the same physical network supporting the unconnected network via a control network RC.

Abstract: Disclosed is a method for the processing of data coming from an adaptation layer for the transmission of messages in the form of a flow of cells on an ATM type asynchronous transfer network, the cells comprising a header followed by an information field. According to this method, the cells are received by a receiver terminal having a working memory and are processed so that the constituent data elements of a message are stored continuously in this memory. For this purpose, the method consists in reserving a memory location with a given maximum size in the working memory of the terminal and in continuously recording the constituent cells of one and the same message at this location. Application to transmission on an ATM network.
