round - trip time造句

• round-trip time
  往返时间,环程时间
• 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tcpip的慢速启动算法、初始窗口、重传超时估计以及改善无线tcpip性能的各种方法，提出了一种把物理层链路和传输层相结合处理往返时间(rtt)的方法：物理层链路采用与信道相关的动态rtt，传输层采用常数rtt，消除了两层rtt之间的相互干扰，从而提高了无线链路的利用率。
