dc.description.abstractSCTP (Steam Control Transmission Protocol)是由IETF[2]提出在傳輸層的新機制。SCTP像TCP一樣提供擁塞控制機制(congestion control mechanism)。此外,SCTP提供Multi-Homing和Multi-Streaming兩個TCP所缺乏的重要機制。然而,SCTP和TCP一樣無法分辨當快速重傳機制(Fast-Rtx)或是Timeout機制啟動時,packet-loss發生的真正原因,如瞬間的通道錯誤或因網路擁塞引起的封包拋棄。於此,SCTP會不正確地啟動擁塞控制機制來防止網路擁塞狀況的持續惡化。\r\n 本篇論文目的在於改善SCTP在無線網路所遭遇效能低落的問題。我們提出三種解決問題的機制,分別是SCTP-EnhancedProbing、SCTP-Duplicate 及SCTP-Changeover。SCTP-EnhancedProbing機制是一種點對點的方法,用以判斷packet-loss發生的真正原因。SCTP-Duplicate機制則藉由multi-homing機制來幫助提升SCTP-EnhancedProbing機制的效能。SCTP-Changeover機制則是一個必要的方法來補足SCTP-Duplicate機制所引發的問題,以提供良好的改善方案。最後,我們將利用網路模擬器NS-2 (Network Simulator ver. 2)來驗證並評估我們所提出三種方法的效能。zh_TW
dc.description.abstractSCTP (Stream Control Transmission Protocol) is a new proposed mechanism by IETF [2] at the transport layer. SCTP has similar congestion control mechanism as that in TCP, and embeds multi-homing and multi-streaming mechanisms that are not offered by TCP. However, SCTP can’t identify exactly whether the cause of packet-loss is from transient channel error or congestion error as fast-transmission or timeout is triggered. SCTP will thus invoke congestion control mechanism incorrectly.\r\nThe objective of the thesis is to improve the performance of SCTP which suffers performance degradation in a wireless network. We propose SCTP-EnhancedProbing, SCTP-Duplicate and SCTP-Changeover three mechanisms for this end. SCTP-EnhancedProbing is an end-to-end mechanism used to identify the cause of packet-loss. SCTP-Duplicate employs the multi-homing feature to enhance SCTP-EnhancedProbing performance. SCTP-Changeover is a necessary complement to SCTP-Duplicate mechanism. Moreover, the proposed SCTP-Changeover is an effective solution to the changeover problem in SCTP.\r\nAt last, we verify and evaluate the performances of the three proposed mechanisms using Network Simulator 2 (NS-2), respectively.en_US
