摘要(中) 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)。
摘要(英) 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.
