Since traditional TCP timer is fundamentally inappropriate for ad hoc network with random abrupt round-trip time(RTT),a new TCP timing scheme based on rtt_active timer was proposed.
针对传统的TCP定时器不适用于具有动态随机变化往返时间的ad hoc网络,提出了一种基于rtt_active定时器的新的TCP定时方案。
Previous tests use round-trip delay to avoid the synchronization problem,but the jitter error can not be neglected.
时间同步是测试中的一个难点,现有的测试方法大多都是测试往返时延,以避开时间同步,但得到的抖动误差很大,所以对单向时延的精确测量是获取网络抖动的前提。
The sum of forward and backward delays of different packets is regarded as one packet’s‘round-trip delay’.
把不同分组在两个方向上经历的最小时延之和看成是同一个分组经历的“往返时延”。
Two limited factors in time division duplex(TDD): capacity loss caused by round-trip delay in sole cell,large region wireless region access network(WRAN) system and performance degradation caused by co-channel interference in multi-cell environment are analyzed.
对时分双工(TDD)方式面临的问题进行了分析,讨论了TDD方式下必须解决的单蜂窝、大覆盖范围的无线区域网络(WRAN)系统中由往返时延引起的系统容量损失问题,以及多蜂窝环境中由于同信道干扰导致的性能下降问题。
