With the rapid growth of rate-based services and wirelessapplications, improving Transmission Control Protocol(TCP)congestioncontrol has been becoming more important in the network researchfield. This paper first Briefly introduces the Additive-IncreaseMultiplicative-Decrease(AIMD)(a,b)algorithm, and then presents an im-Proved TCP congestion control mechanism(D-AIMD)whose principles andsimulation results are discussed in detail. This mechanism can beeasily implemented with lower additional overheads and canefficiently improve network per- Formance. 展开更多
