摘要
提出了一种新的复制机制:温和一致性代理复制机制(MCARM)。MCARM 采用了主节点的复制管理器与辅助节点的 MSS-Agent 协调工作的架构,吸取严格一致性协议和弱一致性协议的优势,又避开其局限性和复杂性,更好地适应移动计算环境的要求,并能与缓存失效策略 CISBMA 协同工作,较好满足了移动应用的需求。
A new mechanism of moderate consistency agent replication mechanism (MCARM) is presented. It adopts a harmonious framework of replication manager in master node and MSS-Agent in secondary node, which has advantage of the tight consistency protocol and loose consistency protocol respectively while avoiding their insufficiency and complexity at the same time so as to adapt well to the mobile computing environments. MCARM can work with CISBMA in harmony to meet mobile application's demand.
