该文提出关于实时IP多播流基于速率弹性的公平性定义,并结合有关多播组规模估计的机制和多播拥塞控制算法,实现了一种基于门限的实时多播业务的等级拥塞控制策略,使实时多播流在满足瞬态弹性公平性的同时,也基本满足稳态的比例公平性,并对此进行了仿真验证.
In this paper, the definition of fairness based on rate elasticity in real-time IP multicast streams is proposed. Based on the mechanism of multicast group size estimation and multicast congestion control algorithm, a level-based threshold congestion control strategy for real-time multicast service So that the real-time multicast flow satisfies the steady-state proportional fairness while satisfying the transient elastic fairness, and the simulation verifies this.
