摘要
基于利用率的接纳控制方法有效地解决了延迟保证服务中的可扩展性问题。这种方法通过配置阶段的延迟演算技术,确定可保证实时应用端到端延迟的每条链路最大可配置带宽数量,将实时的延迟保障测试简化为简单的带宽利用率的检测。然而,如何优化资源配置以提高预分配带宽资源的使用效率是基于利用率方法要解决的重要问题。文章提出一种基于路径的资源配置方法,可有效保证预分配带宽资源在运行阶段被充分使用,减少资源浪费。通过实验验证,发现基于路径的资源配置方法比传统的一致的配置方法能达到更高的接纳概率和有效资源利用率。
Utilization Based Admission Control is a very efficient method,which can provide delay guaranteed service in scalable fashion.This method relies on the configuration time Connection-Population-Insensitive delay computing technique to determine the maximum bandwidth which can be provided in each link to guarantee the end-to-end delay.The run-time admission control is based only on the usage of resources.However,how to optimize the bandwidth configuration to improve the bandwidth efficiency is an important problem to this method.This paper presents a path-based configuring method,which may reduce the resource waste and improve the overall resource utilization.The Simulation experiments show that the path-based method achieves higher admission probability and resource utilization than the uniform method.
