摘要
为实现计算机在通信过程中的可移动性,应对在有线和无线网络之间的数据传输错误原因做出正确判断。为此分析了移动计算机越区切换过程中导致数据丢失和传输层连续超时及传输速率恢复慢的原因,并针对快速重发存在的问题,提出了基于窗口通告值的应答策略,对其原理、设计和性能进行了描述。
In order to achieve the mobility of computers during communication,it is necessary to distinguish between losses due to congestion and non-congestion reasons.This paper analyzes the reasons that result in packet losses,succes-sive timeouts,and slow recovery during and after handoff of mobile computer.Aim at the problem existing in fast re-transmission,propose s a strategy that based on the value of window advertisement of ACK.The principle,design and per-formance of the strategy are described in detail.
