碩士 === 國立臺灣大學 === 電機工程學研究所 === 93 === Due to the fast growth of high bandwidth network, real-time multimedia applications become increasingly popular. Real-time multimedia applications do not use Transmission Control Protocol (TCP) but adopt User Datagram Protocol (UDP) as transport mechanism, which may lead unfair bandwidth allocation or even shut down TCP traffic. In this thesis, a new TCP-friendly congestion control algorithm is proposed to ensure coexistence with TCP traffic, and better qualify in real-time multimedia application performance. The new algorithm is called the Hybrid TCP-Friendly Congestion Avoidance Control (HTCAC). Different from traditional TCP-friendly control algorithms, HTCAC is an active control system which does not passively wait for the happening of congestion but use Round Trip Time (RTT) information to adjust network transmission rate and to avoid network congestion!
