摘要 网络资源的使用情况主要通过节点状态信息表达,其参数的选择在很大程度上决定了网络能支持怎样的QoS要求。通过分析现有网络机制,选择节点延时的概率密度函数作为节点状态信息参数,利用滤波器算法使其正态化,验证此节点状态函数应用于现有网络各类调度算法后,保持正态分布形式不变。这种节点状态的可描述化使得通过求解网络路径各节点延时的概率密度函数来有效地估计本路径的各度量参数变为现实。节点延时的正态化形式使节点状态获取、更新、业务分配、接纳控制及调度机制的计算变得简单,并在一定程度上有利于提高节点状态的平稳性,提高网络效率,达到为网络业务提供相应的统计服务质量保证的目标。 Node - state information is an important factor in QoS research. The Probability Mass Function (PMF) of delay at each node is taken as state information and a filter algorithm is proposed and used for normalizing it. And the simulation proves that the PMF is still a normal distribution function through scheduler. Experimental resuits and theoretical analysis show that the method is effective and feasible in simplifying the network calculation and improving the stability of node - state to meet the corresponding statistical guarantees.
