一种新的拥塞控制算法-PVegas

A New Algorithm of Congestion Control-PVegas

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。

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.
