广泛使用的协议（UDP和TCP）被观察到UDP与TCP比率的变化，弹性（和非弹性）流量行为，以及端口号分布，无论是随着时间的推移还是在不同的网络之间。该研究旨在了解应用趋势（尤其是流媒体的增长）对交通特征的影响。结果显示，随着时间的推移，变化很大，但几乎没有系统趋势的迹象，只有广泛的端口号使用。尽管有大量的网络痕迹，但这些比率似乎相当依赖于应用程序的流行程度（以及它们的分布），因此，如果不考虑至少与我们在这项工作中观察到的一样多的变化，就不能从一个网络上的使用模式推断到另一个网络上的使用模式。
—Widely used protocols (UDP and TCP) are observed for variations of the UDP to TCP ratio, elastic (and inelastic) flow behaviors, and of port number distribution, both over time and between different networks. The purpose of the study was to understand the impact of application trends, especially the growth in media streaming, on traffic characteristics. The results showed substantial variability but little sign of a systematic trend over time, and only wide spreads of port number usage. Despite the large network traces, the ratios appear to be rather dependent on application popularity (and their diversities), and so one cannot extrapolate from usage patterns on one network to those on another without allowing for at least as much variability as we have observed in this work.
