A Hierarchy Model for Dynamic Replacing of Distributed Components
Dejun Wang, Linpeng Huang, Jiankun Wu, Xiaohui Xu · 2007
In this paper, we present a hierarchy model for dynamic updating of distributed components based on message-passing communication mechanism. In this model, multi-components' updating is divided into two level: multi-components' sequential updating from lower to higher level between groups; multi-components' sequential updating from lower to higher in a group. Our model may preserve system state's consistency through coordinating multi-components' updatable-state's arriving and may update multi-components concurrently in different nodes to make updating effective. Accordingly, we propose a prototype framework of a component server supporting this model.
