A Dynamically Scheduling Policy with A Greedy Admission Control Algorithm Based on the Customer (Im)Patience
Wang Kaixi, Yang Fangchun · 2007
The service-driven NGN means that the NGN should be constructed from the perspective of satisfying customers' demands. So controlling the network based on users' willingness is an emerging demand. Based on the psychophysical laws, the paper proposes a dynamically priority queueing system, which employs a greedy admission control algorithm to schedule the services, built on a user patience on the waiting time. The analysis and simulation show that the scheduling policy has more advantages on the system throughput, the waiting time and the degree of a user's satisfaction over other three methods under a heavy load in a multi-service environment. This scheduling policy can meet a multi-service overload control requirements in NGN.
