摘要: 为了有效利用网络带宽、降低网络流量,并在保持逻辑向量时钟的检查点全局一致基础上,使得系统在恢复复制进程时,做到网络流量小、等待时间短、用户费用少,容错系统将依据编辑文档的编辑距离、编辑相似度,以最小的代价为恢复进程提供最新检查点和最新文档,实现广域网环境下优化的实时协同编辑系统。提出流量控制的算法,并通过OPNET建模和实验测试,对整个系统容错时的流量进行了分析。

Abstract: On the base of maintaining the consistence of global snapshot, the flow control needs to satisfy the low thought-out, short waiting time and low cost in WAN. The fault tolerant system provides the low cost of ov or editing document on the foundation of editing distance and editing similarity during the process of editing, optimizing the real time editing system in WAN. The algorithms are put forward about flow control. Then its performance in the system is analyzed by tool of OPNET.
