基于连接件的软件体系结构动态演化

针对基于中间件的软件体系结构（SA）动态演化存在的缺陷，对连接件进行了扩展，使连接件能够对其所连接的实体进行监视和操作；提出了一种支持动态演化的SA风格，使得演化信息可以通过SA自身进行传播．如果连接件之间没有连接通路，则增加一个或多个连接件对SA进行改造．设计了从运行系统中获得SA的算法，使SA成为运行系统的一个可控组成部分．提出了直接对连接件进行操作的SA动态演化框架，消除了SA动态演化的不一致性，提高了演化效率，并具有很好的可跟踪性．

Dynamically Evolving Software Architecture Based-on Connectors

Aimming at the defect of Software Architecture (SA) dynamic evolution based on middleware,the connector definiton was expanded, in this way a connector can monitor and operate on the entities linked with it.A kind of SA style supporting dynamic evolution was given,thus the messages about evolution can be broadcast throught SA itself.If there are connectors without paths between them,the SA can be altered by adding one or two connectors.An algorithm getting SA from the running system was designed.Thus,SA becomes a part of the running system and can be controlled.A SA dynamic evolution way operating on connectors directly was given, thus SA dynamic evolution can be carried through consistently and efficiently.
