ECN冗余模式：一种网络路径拥塞估计的统计方法
ECN verbose mode: a statistical method for network path congestion estimation
摘要：
本文介绍了一种简单而有效的方法来确定网络中的拥塞程度与ECN类似的标记方案。ECN位的目的是通知TCP源即将发生拥塞，以便在丢失发生之前做出反应。然而，ECN是二进制指示符，其不反映瓶颈的拥塞水平（即排队分组的百分比），从而防止任何自适应反应。在这项研究中，我们使用一个计数器，在传统的ECN标记方案，以评估的次数，数据包已通过拥塞的路由器。由于这个简单的计数器，我们驱动一个统计分析，以准确地估计每个路由器的拥塞水平在网络path.We在本文中详细的分析方法验证了一些初步的模拟，证明了可行性和准确性的概念提出。我们总结了本文可能的应用和预期的未来工作。
英文摘要：
This article introduces a simple and effective methodology to determine the level of congestion in a network with an ECN-like marking scheme. The purpose of the ECN bit is to notify TCP sources of an imminent congestion in order to react before losses occur. However, ECN is a binary indicator which does not reflect the congestion level (i.e. the percentage of queued packets) of the bottleneck, thus preventing any adapted reaction. In this study, we use a counter in place of the traditional ECN marking scheme to assess the number of times a packet has crossed a congested router. Thanks to this simple counter, we drive a statistical analysis to accurately estimate the congestion level of each router on a network path. We detail in this paper an analytical method validated by some preliminary simulations which demonstrate the feasibility and the accuracy of the concept proposed. We conclude this paper with possible applications and expected future work.
