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。
Based on the literature [1], this paper further analyzes the performance characteristics of the finite buffer hybrid protocol, simplifies the multi-dimensional Markov chain into a two-dimensional Markov chain by using the new queuing model, and finally makes a horizontal simulation of the finite buffer hybrid protocol. The results show that the throughput of finite buffer hybrid protocol is better than that of CSMA / CD and single buffer hybrid protocol, but the delay performance is slightly worse than that of single buffer hybrid protocol. Under light load conditions, the delay profile is worse than CSMA / CD and better than the CSMA / CD protocol at heavy loads.
