In order to make the current Internet provide better QoS guarantees, many works have been reported in the literature, and many schemes are proposed at different layers of the network. Since the user acquired QoS and the service capability provided by operaters are all obtained from the analysis of the network traffic flow, the research on the characteristics of the network traffic flow is a key problem for improving QoS.

本文致力于基于流量测量的网络QoS改善方面的研究，主要研究内容和创新点如下：1IP网络流量测量的研究：网络流量测量是研究网络行为的基础，而理解网络行为对于更好地管理网络资源，保障服务质量有着重要意义。

We investigate phenomenologically effects of the flavor-dependent quarkonia annihilation on the meson-meson mixing, and find that corrections due to the flavor-dependent quarknoia annihilation can be described by the constituent quark masses in the mixing model which holds for all the meson nonet. We also study the relation between Regge trajectory and meson spectrum, and therefore concluded that the quasi-linear Regge trajectory with the requirements of additivity of intercepts and inverse slopes can describe the meson spectroscopy with good accuracy, and it also holds for the radial excited mesons except for the bbbar mesons.

我们唯象地研究了味道有关的夸克偶素湮灭效应对混合的影响，发现味道有关的夸克偶素间的湮灭引起的修正可以通过组分夸克的质量来描述，考虑这种修正的混合模型可以用于所有的介子九重态；我们也研究了Regge轨迹和介子质量间关系，发现满足截距相加及斜率倒数相加的准线性Regge轨迹可以很好地描述介子的质量，除bbbar外，线性Regge轨迹也可以很好地描述介子激发态的质量；最后，我们借助于赝标介子和标量介子，讨论多个共振态的混合及衰变。
