Title (EN) METHOD AND APPARATUS IN A PACKET SWITCHED NETWORK
(FR) PROCEDE ET APPAREIL DANS UN RESEAU A COMMUTATION PAR PAQUETS
Abstract:
(EN) A method for the relative flow control of a data flow, and a switch in which the method may be applied, are described. A buffer unit that reaches a certain degree of fullness sends a message to all units from which it receives data that it cannot receive any more data or that it can only receive at a reduced rate. The message is forwarded by each unit that receives it, to each unit from which it receives data and comprises a level indicator field, which is incremented for each unit it passes. For each unit passed a field is also added, identifying the unit from which it was received. Each unit is denoted by its number among all units receiving packets from the level above it. The message may be valid either for a certain period of time or until a new message is transmitted indicating that the problems have ceased.
(FR) L'invention concerne un procédé permettant de commander un flux relatif de données, et un commutateur dans lequel ce procédé est appliqué. Une unité tampon qui atteint un certain degré de saturation émet un message à toutes les unités qui lui envoient des données. Dans ce message, elle dit ne plus pouvoir recevoir de données ou ne plus pouvoir en recevoir qu'à une vitesse réduite. Le message est acheminé par chaque unité qui le reçoit, à chaque unité lui envoyant des données et comprend un champ indicateur de niveau, qui est incrémenté pour chaque unité par laquelle il passe. Pour chaque unité passée, un champ est également ajouté, identifiant l'unité ayant reçu le message. Parmi toutes les unités recevant des paquets du niveau supérieur, chaque unité est identifiée par son numéro. Le message peut être valide pendant une certaine durée ou jusqu'à ce que soit émis un nouveau message indiquant que les problèmes ont cessé.
