An Improved TCP Congestion Control Algorithm and Simulation

Although TCP protocol provides connection-oriented and reliable service,when applied to delay-sensitive real time network,it can't guarantee timeliness.When the network load increases,problems like congestion,delay and packet loss will also emerge.To reduce congestion probability,an improved TCP congestion control algorithm TCP-EB is proposed.It estimates the network's available bandwidth by packet acknowledgement speed,adjusts the congestion window number as well to make good use of bandwidth.When congestion occurs,it limits the descent rate of windows to provide a privileged transmission over other data flow.In the end,a comparison among TCP-EB and TCP Reno and TCP Vegas is implemented.The result shows TCP-EB can increase the network throughout and smoothness.
