Apparatus and method for the optimization of fair maximum and minimum transmission speed control in abr - sessions

摘要

It is under the network of a lead fairness seat by a service with available bit rate (abr) in a network compete supplied asynchronous transfer mode switch, in that for each connection is determined a stoppages information. Abr - cells are monitored, in order to determine which rates information per according to the outside would like to ndem connection on the basis of abr - cells of a switch leaves. With the use of the abr - rate per connection, the available capacity and the input rate of the output queues, a connection stoppages parameters (lcp) is determined. Resources management cells (rm - cells), which run through the switch, are monitored, in order to determine whether the new lcp lower than the explicit rates field (it - field) in the rm - cell is. If the new lcp is lower, then the new lcp inserted into the rm - cell. If the transmitter receives the lcp - value, then the transmitter output rate is set on the basis of the lcp. Since the lcp on the basis of the traffic flow is determined per connection, a fairness under the sessions, which compete an available abr - capacitance supplied.
