  1. Rtt round trip time

    封包來回時間
  2. Round - trip time

    往返時間，環程時間
  3. We studied many methods to improve the tcp / ip in wireless environment, such as tcp / ip initial slow start algorithm, initial window and retransmission time out ( rto ) estimate. finally, we consider the round - trip time ( rtt ) with the physical layer and the transfer layer combined together. physical layer using rtt related to the channel state and transfer layer using the constant rtt, the interference between the two layers can be eliminated, and so the effectiveness of the wireless data link can be enhanced

    研究了tcp ip的慢速啟動演算法、初始窗口、重傳超時估計以及改善無線tcp ip性能的各種方法，提出了一種把物理層鏈路和傳輸層相結合處理往返時間（ rtt ）的方法：物理層鏈路採用與通道相關的動態rtt ，傳輸層採用常數rtt ，消除了兩層rtt之間的相互干擾，從而提高了無線鏈路的利用率。
  4. An application can save time by preauthenticating the user with the resource, thus eliminating at least one round trip to the server

    應用程序可以通過用資源預驗證用戶的身份，從而消除至少一次與服務器間的往返行程並因而節省時間。
  5. The end - to - end tcp congestion control based on the window mechanism cause the throughput of tcp connection inversely proportional to the connection round trip time ( rtt )

    Tcp端到端的擁塞控制機制使得tcp連接獲得的瓶頸帶寬反比于rtt 。
  6. We firstly study some aspects, such as the modulation ( ofdm ) in the physical layer and the media access control ( mac ) protocols, combining reliable data transmission with high - throughput access methods and real - time, quality - of - service ( qos ) features. some problems exist in tcp applications over plc, because the high bit error rate makes it difficult to estimate the round trip time ( rtt ) and causes unnecessary retransmission

    通過對現有的兩種產品（ homeplug和inari ）的mac協議：類似無線通訊csma ca協議（以競爭為基礎）和集中式的令牌環（ ctp ）協議（避免競爭）的媒質接入控制的原理進行分析和計算，對兩個協議進行了性能評價及分析了它們對qos的支持。
  7. Round - trip propagation time

    往返傳播時間
  8. Round trip propagation time

    往返傳播時間
  9. In this paper, it simulates the system action under the different initial conditions and different round trip time

    文中討論了不同的rtt （ roundtriptime ）和不同的初始條件下系統的行為。
  10. With the evolvement of internet based on tcp / ip, the scale, users and traffics of it have experienced an explosive growth since 1990 ' s. the network congestion has become more serious and complex due to the ever - increasing network application types and dynamic network parameters such as active sessions and round trip time

    以tcp ip協議為基礎的internet自從九十年代以來，其網路規模、用戶數量及業務量都呈現爆炸式的增長，新型網路應用也不斷涌現，網路的參數（如激活的連接數、迴路往返時間）動態變化，這些使得網路擁塞的狀況愈加嚴重和復雜。
  11. We chose suitable tcp throughput model to estimate the available bandwidth correctly, using the estimated round trip time and packet loss ratio for the next time interval as parameters of the model to achive the accuracy of estimated network bandwidth. as the observed losses and round trip time vary very dynamically, adjust the sending rate equivalent to the amount of tcp throughput may result in a rather fluctuant sending rate. so we present a rate adjustment like tcp congestion control based on aimd, which increases its sending rate by an additive inereease rate

    根據mpeg4視頻流應用的特點，選擇合適的吞吐量模型，進行合理的參數估計，並根據計算出的帶寬進行相應的速率調整來實現擁塞控制，我們使用未來rtt的估計值和分組丟失率的估計值作為吞吐量模型的參數，增強了控制的實時性，弱化了業務的振蕩性，提高了帶寬預測的準確性；在進行速率調整時，不是簡單地將發送速率調整到與tcp吞吐量模型一致，而是採用類似tcp的aimd策略來調節發送速率，減小了發送速率的振蕩性。
  12. For example, a first time zuji purchaser can earn up to 9, 000 asia miles on one trip alone by booking two round - trip tickets to the featured destination, one hotel accommodation and one car rental all on zuji. further details on zuji travel packages will be available in september. asia miles details are available by visiting zuji. com. hk

    ?在香港，超值的旅遊優惠仍然是外游的最大誘因，有23 %的香港旅客是在出發前一星期才預訂亞太區平均則為19 % ，主要是被zuji推出的最後一刻特別優惠所吸引。
