模糊漏桶在ATM网络UPC中的应用

The Application of Fuzzy Leaky Bucket in UPC of the ATM Networks

本文提出了模糊漏桶模型，研究了它与普通漏桶在用户量参数控制（ＵＰＣ）中的作用。由于ＣＡＣ初步协议的不完全合理性，在实际应用中动态调节是必要的；仿真结果表明在降低信元丢失率、时延和时延抖动方面，及在动态利用网络资源方面，模糊漏桶算法要比普通的优越。我们还给出了合适的模糊控制规则。

in this paper, we present a fuzzy leaky bucket (FLB) model and study its effect with normal leaky bucket(LB) in Usage Parameter Control(UPC). Since the first contract of Call Admission Control (CAC) may be not reasonable, dynamic adjustment is necessary during practical application. Simulation results show that FLB algorithm is better than LB in some aspects of lowering cell loss probability, improving delay and delay jitters, and utilizing efficiency of resource.At last, we give the proper fuzzy control rules.
