随着网络用户的增加和所承载业务流的多元化,端到端拥塞控制正面临着严峻的挑战。而路由器是互联网的核心实体,也是网络拥塞状态最直接的感受者,因而充分发挥路由器在拥塞控制中的作用也是解决拥塞控制问题的有效思路。本文提出一种基于IP,利用改进路由机制实现主动拥塞控制方法。 With the increase of network users and diversified service flows, end-to-end congestion control is facing severe challenges. The router is the core entity of the Internet, but also the most direct network congestion state of the feelings, and thus give full play to the router in the role of congestion control is also an effective solution to congestion control problems. This paper presents a method based on IP to improve the routing mechanism to achieve active congestion control.
