文中针对越来越多的网络应用不采用端到端拥塞控制机制而导致非公平占用网络带宽问题，介绍了在路由器内部实现基于连接调度的增强拥塞控制方法．路由器使用公平排队调度算法代替传统的先来先服务调度算法，可隔离和保护基于漏桶控制的网络连接．但采用基于窗口反馈拥塞控制机制ＴＣＰ连接会对数据包丢失敏感，路由器使用公平排队调度算法还需要结合相应的缓冲管理方法，才能保证ＴＣＰ连接获取公平的吞吐量．文中还讨论了基于连接的排队数据包公平缓冲丢弃的缓冲管理方法．模拟结果表明，公平排队调度算法结合文中所提出的缓冲管理方法比随机提前检测缓冲管理方法可更好地改进拥塞控制性能．
In this paper, an increasing number of network applications do not use end-to-end congestion control mechanism resulting in unfair occupation of network bandwidth. This paper introduces the implementation of enhanced congestion control based on connection scheduling in routers. Routers use fair queuing scheduling algorithms instead of traditional first-come, first-serve scheduling algorithms to isolate and protect network connections based on leaky bucket controls. However, the TCP connection based on window feedback congestion control mechanism will be sensitive to packet loss. The router uses the fair queuing scheduling algorithm also needs to combine the corresponding buffer management methods to ensure fair throughput for TCP connections. The paper also discusses the buffering management method of fair buffering and discarding of connection-based queued packets. The simulation results show that the fair queuing scheduling algorithm combined with the proposed buffer management method improves the congestion control performance better than the random early detection buffer management method.
