摘要

分析了跨fddi虚拟电路动态自适应带宽分配机制的最优性。该算法基于对互联单元缓冲区状态的监控以及当缓冲区内容超过给定阈值时对带宽量的请求。利用所提出的分析模型,可以对n级带宽量化算法的性能进行分析。结果,通过仿真验证,允许比较三层和两层算法。三级算法对输入流量的统计波动有更好的响应,同时提供更好的服务等级。

Analysis of the optimality of a multi-level bandwidth-negotiation algorithm for FDDI interconnection across B-ISDN
The optimality of a dynamic adaptive bandwidth allocation mechanism on the inter-FDDI virtual circuits is analyzed. The proposed algorithm is based on the monitoring of InterWorking Unit buffer status and the request of quanta of bandwidth as the buffer content exceeds given thresholds. By using the analytical model proposed, the analysis of N-level bandwidth quantization algorithm performance can be carried out. The results, validated by simulation, allow comparison between three-level and two-level algorithms. The three-level algorithm shows a better response to statistical fluctuations of input traffic, while offering a better grade of service.<>
