研究了TCP/IP网络中随机早期检测（RED）主动队列管理算法。随机框架建模的RED算法的性能。我们引入了一个二维二阶离散时间马尔可夫链来模拟数据包丢弃对传入流量的反馈影响。平均系统占用率，丢包概率，和系统吞吐量的分析模型计算标记和丢弃策略。RED参数上的一组选定的性能指标的影响进行了研究。
This paper considers the random early detection (RED) active queue management algorithm in TCP/IP networks. A stochastic framework for modeling the performance of the RED algorithm is presented. We introduce a two-dimensional second-order discrete-time Markov chain to model the feedback effect of packet dropping on the incoming traffic. The mean system occupancy, packet drop probability, and system throughput are computed from the analytical model for both marking and dropping policies. The effects of RED parameters on a selected set of performance metrics are studied.
