Abstract
A dynamic admission control(AC) mechanism for accepting traffic service requests to a carrier IP network based on an iterative measurement method, is disclosed. For each service offered, a network planner assigns a certain amount of resources. A QoS manager keeps track of the amount of unused resources for each particular service. The amount of unused resources are estimated using actual measurements of load levels on various links of the network. Each router monitors the loading level on each of its outgoing interfaces. Those measurements are then transferred to the QoS manager upon request, or periodically at time intervals “T”.
