Abstract:
1. A method for selective admission of traffic packets to a telecommunication switch, the method comprising: storing, in a common input queue, a first plurality of high class packets received at a first rate and a second plurality of low class packets received at a second rate; determining whether the switch operates under a stress state based on a congestion at the common input queue and on a throughput of the switch; delaying transfer of a first part of the second plurality of low class packets to a next processing block in case the switch is determined to operate under the stress state; based on the throughput of the switch and the first rate of the first plurality of high class packets, calculating an instantaneous leftover throughput; transferring all of the first plurality of high class packets from the common input queue to the next processing block; and transferring a second part of the second plurality of low class packets from the common input queue to the next processing block on a basis of the instantaneous leftover throughput, wherein a maximum admission rate L of the second plurality of low class packets is: L=T′−α*H, and wherein: H is an instantaneous rate of high class packets recently admitted by the switch; α is a coefficient having a value of 0<α≦1; T′ is a pre-defined limit of the switch throughout wherein T′≦T; and T is the switch throughput.
