摘要
R-OSGi(Remote-OSGi)作为OSGi(Open Service Gateway Initiative)的一种分布式扩展,为OSGi服务平台应用到普适计算领域提供了可能性,但它的容错能力有限。文章结合R-OSGi以及分布式系统容错中间件等相关技术,提出了一个基于OSGi框架的容错层,使用的是服务方法,即它不修改底层OSGi以及R-OSGi的结构,只使用它们的服务,为普适应用的开发提供了一定的容错。
R-OSGi,as a distributed extension of OSGi,offers the possibility of applying OSGi to pervasive computing,but its fault tolerant capability is limited.The paper presented a service proxy of fault tolerance based on OSGi,combined with the related technologies of R-OSGi and distributed fault-tolerant middleware.The service proxy of fault tolerance provided fault tolerance for pervasive computing without modifying the structure of OSGi or R-OSGi but used their service.
