摘要为解决命名数据网(Named Data Networking,NDN)中混合拥塞控制的过度控制问题,提出一种协同拥塞控制方案CHCC(Cooperative Hybrid Congestion Control),不仅支持接收端和路由器协同缓解拥塞,还能够防止由于两者过度控制导致的传输性能下降。CHCC通过主动队列管理技术检测拥塞并产生标记信息,触发下游接收端调整Interest发送窗口、路由器转移流量来控制拥塞。在ndnSIM中实现该方案,并与ICP(Interest Control Protocol)方案进行对比,结果表明CHCC在多种拓扑下均能获得更高的吞吐量,更低、更稳定的传输延时,同时无丢包现象,此外,通过Jain's公平性指数进行公平评价,结果表明CHCC在确保用户间资源分配公平方面同样非常有效。 In order to solve the over control problem of hybrid congestion control in named data networking(NDN),a cooperative congestion control scheme CHCC(cooperative hybrid convergence control)is proposed,which not only supports the receiver and router to jointly alleviate congestion,but also prevents the transmission performance degradation caused by their over control.CHCC detected congestion through active queue management technology and generated tag information,triggering the downstream receiver to adjust the interest sending window and router transfer traffic to control congestion.This scheme was implemented in ndnSIM,compared with the ICP(interest control protocol)scheme.The results show that CHCC can obtain higher throughput,lower and more stable transmission delay and no packet loss under various topologies.In addition,the fairness evaluation was carried out through Jain's fairness index.The results show that CHCC is very effective in ensuring the fairness of resource allocation among users.
