| 摘 要： | 混沌动力学系统具有初始条件的极端敏感性,当参数空间发生漂移时,系统的解空间将出现很大的变化.以Feigenbaun映射为例,分析了参数引起的分叉行为,提出利用混沌周期解提高测试系统灵敏度的方案.调整参数使测试系统工作在周期解的区域,根据参数敏感激发混沌系统周期数变化,设计了测量算法改善测量的精度和灵敏度,对混沌系统的抗干扰性进行了分析.

| Abstract: | The introduction of MPLS into Internet makes the Internet traffic engineering possible.It is important to balance the traffic load among several parallel explicit LSPs so as to avoid congestion and optimize the network capacity.The total traffic delay is the most valuable and practicable optimization object for traffic engineering.By analysing the constraint relationship between average packet delay and traffic load,the existence of optimum solution is proved and its mathematical result is gotten.Anovel adaptive traffic contribution method based on such optimization object is proposed in the paper.Both theoretical analyses and simulation bear out the merits of simpleness.speediness and convergence. |
