针对分布式协同编辑系统中基于操作转换的并发控制算法的性能问题,提出并实现了基于二维有序状态向量的操作转换算法,较好地解决了并发控制的效率问题。设计了LateComer协调机制,扩展了原有的算法,增强了协同编辑过程的连续性。
Operation transformation technique is not perfect in solving concurrency control of real-time distributed cooperative systems. This article proposes 2-dimension sequential state vector operation transformation algorithm and also presents a solution of LateComer. The algorithm improves efficiency and continuity of cooperative editing.
