In this paper, new local stabilization analysis for TCP/AQM process based on segmented delay is proposed. The new approach consists in describing the time delay as a sum of homogeneous loads delays plus the variation of the queuing delay resulting from the made actions inside the router buffer. By employing an appropriate new Lyapunov–Krasovskii functional that depends on the upper bounds of the loads, new segmented delays dependent local stabilization conditions are proposed. Furthermore, new results concerning the unsymmetrical saturation input are obtained. Finally, the theory is experimented on NS 3, which proves that the proposed Segment Controller (SegCont) mechanism is strong and robust.

本文提出了一种基于分段时延的TCP / AQM过程局部稳定分析方法。新方法包括将时间延迟描述为同类负载延迟的总和，再加上路由器缓冲区内部进行的操作所导致的排队延迟的变化。通过采用取决于载荷上限的适当的新Lyapunov–Krasovskii泛函，提出了依赖于局部稳定条件的新分段延迟。此外，获得了有关非对称饱和输入的新结果。最后，在NS 3上对该理论进行了实验，证明了所提出的分段控制器（SegCont）机制强大且健壮。
