摘要:

为了解决端点接纳控制方法探测延时长、探测结果不准确等难题,在端到端探测的基础上,在接入网引入局部探测,提出了一个局部与端到端联合接纳控制算法. 通过局部探测,该算法精确估计了接入网的资源状况. 仿真结果表明,该算法改善了接纳控制的性能,并在接入网重载时,减少了用户的平均等待时间.
关 键 词:接纳控制;服务质量管理;接入网;区分服务

Abstract:

To solve the difficult problem of long probing delay and inaccurate probing results in endpoint admission control method, a joint local and end-to-end admission control algorithm is proposed, which introduces local probing of access network besides end-to-end probing. Through local probing, the algorithm accurately estimates resources status of access network. We show through simulation that this algorithm can improve admission control performance and reduce users’ average waiting time when access network is heavy-loaded.

Key words: admission control, QOS management, access network, DiffServ
