摘要: The time delay-induced instability in an Internet congestion control model is investigated. star topology considered, and the link bandwidth ratio gain are selected as tunable parameters for suppression. stability switch boundary obtained by eigenvalue analysis linearized system around equilibrium. To investigate oscillatory when equilibrium becomes unstable, center manifold reduction normal form theory used to study periodic oscillation induced delay. theoretical numerical simulation show that between bandwidths of trunk regular link, rather than these themselves, crucial system. present results demonstrate it not always effective increase stabilizing system, some certain delays, adjusting more efficient.
