On line call admission control algorithm based on multi class traffic resources sharing
Lu Guo · Journal of China Institute of Communications · 2001
Based on multi class services,this paper proposes an On line Call Admission Control algorithm for multi class resource sharing(OCAC).OCAC can dynamically adjusts the resource allocation based on the measured quality of service for QOS traffic class and congestion states for BE traffic class.Advantages of OCAC include efficient use of resources,stringent QOS control and being able to improve the throughputs of best effort traffic.In addition,this paper also examines two kind of schemes which implement OCAC algorithm for multi hop,the scheme based on each node(ENS)and based on the source node(SNS).Finally,simulation has been done to show the efficiency of OCAC algorithm,and the simulation results show that OCAC algorithm can heighten throughputs for BE traffic and save resource available by comparing to the static call admission control algorithm.
