基于多种业务流资源共享的在线呼叫接入控制算法

On line call admission control algorithm based on multi class traffic resources sharing

本文针对多种业务类型提出了一种在线呼叫接入控制算法 (OCAC)。OCAC算法是基于QoS业务量的服务质量要求和BE业务量的拥塞状态来动态地调整资源的分配 ,目的是更有效地利用资源并且在QoS业务流调整服务质量的同时 ,改善BE业务量的吞吐量。针对多跳的情况 ,本文描述了OCAC算法的两种实现方案 ,即基于每个节点和基于源节点的OCAC实现方案 (ENS和SNS)。最后给出了仿真结果 ,并对本文提出的算法和静态接入控制算法的仿真结果进行了比较 ,进一步说明OCAC算法的有效性。

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.
