一种改进的基于探测的接纳控制机制

接纳控制作为一种预防性的流量控制手段是实现网络服务质量（QoS）保障的重要手段。本文在研究基于测量的接纳控制技术原理的基础上，着重分析了基于探测的接纳控制方法存在的问题，并对其中的“链路带宽重复评测”问题的解决方法进行了改进，提出了基于资源预留标签探测机制并给出了探测流程，最后通过仿真验证了该探测机制的有效性。

An Improved Probe-Based Admission Control Scheme

As a precautionary method of Traffic Engineering, Admission Control is an important method to realize the Network Quality of Service. On studying the fundament of Measurement-Based Admission Control, this paper mainly analyzes the demerits of Probe- Based Admission Control and improves the solution to the problem of repeated-evaluating link-bandwidth. A novel probe method called Label-RSVP-Probe-Based Admission Control is proposed and the process of the novel probe method is also given in this pa- per, Finally, results of simulation show the effectiveness of the novel method.
