Abstract:  In order to make the NGN (Next Generation Network)service developers quickly and flexibly develop
and deploy business, the concept of resource admission control is introduced to realize the separation of business
control and resource transfer. Based on the research of the application server admission control model, this paper
analyzes the resource allocation mechanism of admission control algorithm and uses matlab to simulate the
algorithm. The simulation results show that the admission control PIAA (Parameter Iterative Adaption Algorithm)
algorithm can well accomplish the task of application server admission control.

Key words: next generation network (NGN), overload detection, application server, admission control technology
