  Abstract

This paper presents the control structure for incoming traffic from arbitrary node to provide admission control in policy-based IP network management structure using fuzzy logic control approach. The proposed control structure uses scheme for deciding network resource allocation depending on requirements predefined-policies and network states. The proposed scheme enhances policy adapting methods of existing binary methods, and can use resource of network more effectively to provide adaptive admission control, according to the unpredictable network states for predefined QoS policies. Simulation results show that the proposed controller improves the ratio of packet rejection up to 26%, because it performs the soft adaption based on the network states instead of accept/reject action in conventional CAC(Connection Admission Controller).
