【摘要】 针对源端算法TCP Vegas在持续拥塞和公平性等方面的不足,该文引入非线性最优化流控理论,把TCP Vegas和中间结点算法有效地结合起来,提出了一种新拥塞控制算法:PVegas(价格Vegas算法)。仿真结果表明,该算法不但能很好地解决网络的持续拥塞,而且相对于TCP Vegas有更好的公平性、稳定性以及低丢包率。更多还原

【Abstract】 Aiming at the insufficiency of TCP Vegas,these include persistent congestion and fairness,this paper introduces the non-linear theory of optimization flow control,combines the TCP Vegas algorithm and link algorithm effectively,puts forward a new con-gestion control algorithm:PVegas(Price Vegas).The simulation results show that the algorithm not only can solve persistent conges-tion of network very well,but also have better fairness,stability and lower packet loss than TCP Vegas.更多还原
