| 中文摘要 |
| 研究了非线性、时变时滞的快速传输控制协议(FAST TCP)系统的全局稳定性. 首先, 利用其时滞变化与源端发送窗口变化成比例关系和其非线性函数是严格单调递减函数这两个特性, 计算每个振荡周期的解轨迹界, 建立计算轨迹界的改进型迭代公式, 得到了比已有结论更低保守的全局稳定性条件. 最后, 通过网络模拟器2(NS-2)仿真实例验证了改进的全局稳定性条件的有效性. |
| 英文摘要 |
| We investigate the global stability of the nonlinear fast active queue management scalable transmission control protocol (FAST TCP) system with time-varying time-delay. By considering that the time-delay variation is proportional to the sending window variation of the TCP source and the nonlinear function is strictly monotonically decreasing, we present the improved iterative formulas for calculating the trajectory bounds and determining the trajectory bounds of the FAST TCP system in each oscillating period. For the FAST TCP system, we develop a global stability condition which is less conservative than the existing one. The effectiveness of this improved global stability condition is validated by the network simulator 2 (NS-2) simulation results. |
