Abstract:
Method of putting a flow of packets of a network for transporting packets of variable length into conformity with a traffic contract, the method consisting, at each arrival of a packet, of comparing the time of this arrival with a theoretical arrival time and, if this arrival time is earlier than the theoretical time by more than the jitter tolerance defined in the contract, destroying the packet or not further processing the packet, otherwise retransmitting the packet and then determining the theoretical arrival time for the next packet, characterised in that, in order to determine the theoretical arrival time for the next packet, it consists of adding a time ti related to the present packet i and which is a function Æ’ of the theoretical arrival time TATi and of the actual arrival time &thgr;i of the packet i to an interpacket time Ti which is a function g of the negotiated time per unit length T defined in the traffic contract and of the length &lgr;i of the current packet i:TATi+1=ti+Ti=Æ’(TATi, &thgr;i)+g(T, &lgr;i).
