在本論文中，我們提出並分析一套新的網路壅塞控制機制TMRC（Time-based Model Rate Control），使其能夠應用在即時多媒體（Real-time Multimedia）的環境上。TMRC為使用以時間為基礎的端點對端點壅塞控制機制，能夠估測出適當的傳輸速率，同時確保與其他網路連線相互競爭時的公平性。 使用TMRC，傳送端可以依據接收端所估測出來的數值，精確地調整其傳輸速率，以提供與TCP友善且公平的競爭分享網路頻寬，同時也確保網路資料傳輸時，速率的穩定性。如此的特性，使我們所提出的方法能夠符合即時多媒體串流的需求。 為了展示TMRC的效能，我們將與其他TCP-Friendly速率控制機制做比較，如TFRC（TCP-Friendly Rate Control）。 In this paper, we introduce and analyze a new congestion control approach for real-time multimedia applications, called TMRC (Time-based Model TCP-Friendly Rate Control). TMRC is a time-based end-to-end congestion control mechanism, which could estimate an adequate sending rate and assures the fairness against competing flows. Via this mechanism, the sender can explicitly adjust its sending rate as a function of the measured rate reported by the correspond receiver. In long term, TMRC acts as a TCP-friendly flow with the same throughput as other flows while in short term it performs more stable in its sending rate. This makes our mechanism suitable for real-time multimedia applications. To demonstrate its better performance, this paper also compare TMRC to other representative TCP-friendly rate control mechanism, such as TFRC.
