Albert Lespagnol, Jacques Y Kerberenes: Method and system of control of flow of data packets. L etat Francais Represente par le Ministre des PTT Centre National d Etudes des Telecommunications, Laff Whitesel Conte & Saret, January 23, 1990: US04896316 (36 worldwide citation)

The packet flow of each virtual circuit is measured and compared to an allocated average value. At each transmission authorization request (DAE'), when found to be less than the average value, a positive difference brings about an authorization to transmit and is translated into a right to transmit ...
