有限缓冲混合协议性能分析

Performance Analysis of Buffered Hybrid Protocol

本文在文献[1]的基础上进一步分析有限缓冲混合协议的性能特性,利用新的排队模型将多维马氏链简化为二维马氏链,最后对有限缓冲混合协议进行了横拟研究。结果表明有限缓冲混合协议的吞吐量优于CSMA/CD及单缓冲混合协议,但延时特性比单缓冲混合协议略差。在轻负载条件下,延时特性比CSMA/CD差,重负载时优于CSMA/CD协议。

In this paper, the performance and charactristic of Buffered Hybrid Protocol is analysed, a new kind of queue model is used to simplify a mulli -dimensional Markov Chain to a two-dimensional Markov Chain, Buffered hybrid protocol is studied simimulatically finally The result shows that turoughout performance of buffered hybrid protocol is better than CSMA /CD protocol, and delay oi buffered hybrid protocol is worse than hybrid protcol whose Buffer is one unit On low load, delay is worse than CSMA/ CD. On high load, delay is better than CSMA/CD.
