A system and a process arranges equitable-loss data packets in a high-volume asynchronous transfer mode (ATM) system and establishes the output order of the packets. There are a plurality of inflowing data packet streams, a minimum quantity r of each incoming flow being reserved. At all times, there is a ratio K(t) between two parts of each incoming data packet flow. One part is a quantity of packets &Dgr;x (t) allocated above the minimum reserve quantity r . The other part e (t) is an instantaneous quantity &Dgr;x (t) above the minimum reserve quantity r .

Process for the arrangement of equitable-loss packets

The invention provides a method of verifying the integrity of sequences of data transmitted from a first station to a second station in a broadcast network during a call set up between the first and second stations. First and second encipherment seals are calculated in a control station separate from and independent of the first and second stations, respectively in response to reception of a sequence corresponding to the transmitted data sequence and in response to reception of the sequence which is received in and retransmitted by the second station. A comparison of the calculated seals for integrity verification is preceded in the control station by searching for the first seal calculated according to an identification word of the sequence which is retransmitted by the second station. The invention relates to a method of verifying the integrity of data sequences exchanged between stations respectively belonging to different broadcast networks.
