Abstract
This invention relates to a process for automatically allocating appropriate communication rates to different data communication lines connected to a common multiplex channel, in terms of the traffic on these lines and the available maximum rate S on this channel, so as to improve the data throughput on the common channel. To this end, Traffic T.sub.i.sup.n is, first, valuated on each line at time t.sub.n, according to formula: T.sub.i.sup.n =.beta.F.sub.i.sup.n +(1-.beta.)T.sub.i.sup.n-1 In this formula: PA1 T.sub.i.sup.n-1 is the traffic valuation at time t.sub.n-1, PA1 .beta. is a coefficient within 0 and 1, PA1 F.sub.i.sup.n is given by formula: EQU F.sub.i.sup.n =b.sub.i.sup.n [.alpha.+(1-.alpha.)V.sub.M /V.sub.i ] wherein PA1 b.sub.i.sup.n is the number of the bits "0" transferred on to the considered line between times t.sub.n-1 and t.sub.n, PA1 .alpha. is a coefficient within 0 and 1, PA1 V.sub.M is the highest operating rate on the line, and PA1 V.sub.i is the actual rate on the considered line. Once the traffic T.sub.i.sup.n has been valuated for each line, each of the values T.sub.i.sup.n is associated with available rates so that the discrepancies between these traffic …
