应用共享并发与冲突机制研究

Study on Mechanism of Concurrency Control and Collision in Application Sharing

论文分析了应用共享技术“共享显示法”与“事件分发法”中的并发冲突问题,重点探讨了“事件分发法”系统中并发控制机制存在的主要问题,提出了在相容优先方式下“全局序列”与“改进的多版本机制”相结合的并发机制,设计了采用有向图结构存储冲突版本的“事件”序列的方法;设计了非相关”事件”的合并规则。该机制提高了相容优先方式下系统处理冲突的能力,同时节省了空间与时间开销。

This paper analyzes the concurrency and collision mechanism in the application sharing technology of the“share display method”and the“event dispense method”,brings forward a concurrency mechanism based on the“entirely sequence”and the“reformative multi-version mechanism”,The author designs a method by using the digraph storage Collision version sequence and the incorporate rule of the non-correlation“event”.The mechanism has improved the system ability of dealing with collision.
