Study of Packet Delay and Control Strategy
Jin Hu · 2006
Many network applications run over TCP rather than UDP because they want to make use of TCP’s reliable transport service. But an application developer choosing TCP gets not only reliable data transfer but also TCP congestion control. We have just seen how TCP congestion control regulates an application’s transmission rate via the congestion-window mechanism. TCP implements an end-to-end congestion-control mechanism with slow start and congestion avoidance.
