A Serial Traffic Control Algorithm Based on the TCP Sliding Window in the Netfilter/Iptables Framework
HE Shi-ming · Computer Engineering and Science · 2009
The traditional traffic control algorithms based on traffic shaping,usually require a corresponding queueing model,which leads to the complexity of implementation.Furthermore,all datagram have to wait in the shaping queues,which increases the delay time.This article starts from the TCP congestion control protocol and the datagram grouping mechanism,puts forth a serial traffic control algorithm based on the TCP sliding window,which changes the sender's window size for the purpose of controlling the traffic as well as reducing the shaping and queueing delay time.The implementation and experimentation of this algorithm in the Netfilter/Iptables framework,via comparing different sets of parameters for the performance and comparing with the CBQ algorithm,show the effectiveness and efficiency.
