Brief description of a traffic contract conformity has a flow of packets of a network of the transport packets a variable length

摘要

The present invention relates to a method conforming to a traffic contract a flow of packets of a transport network of packets of variable length. Said method is of the type which consists in each arrival of a packet, to compare the time of this inlet to a theoretical arrival time and, if the time of arrival is prior to the theoretical time of more than the jitter tolerance defined in the contract, destroying the said packet or do not take into account, otherwise reemitting said packet and then determine the theoretical arrival time for the next packet. According to the invention, it is characterized in that, in order to determine the theoretical arrival time for the next packet, it consists in adding a time ti, which is connected to this packet i and which is a function f of the theoretical arrival time tati and the actual arrival time thetai of said packet i to the interpacket time ti, which is a function g of the negotiated time per unit length t defined in the traffic contract and the length lambdai; the current packet i / p
