ABSTRACT:
Method for admitting new voice calls to a VoIP network. Various points in the network are polled to generate a link utilization parameter. Parameters denoting threshold values of link utilization in the network are compared to the link utilization parameter. A first comparison is made between a first (current) link utilization parameter and first and second link utilization threshold parameters. Then, a second comparison is made between the current link utilization parameter and a second (previous) value of link utilization. A calculation of new calls allowed into the network is performed based on these comparisons and whether the current level of link utilization is rising or falling when compared to a previous level of link utilization.
