| 摘 要： | 阐述一种改进算法以解决由不同服务动态组成的SOA进程运行时,一些服务出错引发进程违背端到端服务质量约束的问题.通过查找具有可替换服务的重构域,替换出错服务及其相关服务.替换可由一对一,一对多或多对一的函数映射来实现,由于只替换重构域中的服务而不是整个服务进程,降低了重构经费和服务进程崩溃的风险.最后在Llama的ESB企业服务总线中进行实验模拟,结果表明该算法能有效地修复SOA进程.

| Abstract: | This Paper presents an improved algorithm to resolve the violating of end-to-end quality of service (QoS) constraints,which occurs when SOA processes running with some services' wrong.By searching for a reconfiguration region that has replaceable services,the study replaces only faulty services and some of their neighboring services.And the replacements can be implemented with one-to-one,one-to-many,or many-to-one functions mappings,as replacing only services in reconfiguration regions rather than the whole... |
