摘要: The FRIENDS system developed at LAAS-CNRS is a metalevel architecture providing libraries of metaobjects for fault tolerance, secure communication, and group-based distributed applications. use provides nice separation concerns between mechanisms Metaobjects can be used transparently by applications composed according to the needs given application, architecture, its underlying properties. In FRIENDS, are recursively add new properties They designed using an object oriented design method implemented on top basic services. This paper describes software-based object-oriented development metaobjects, experiments that we have done, summarizes advantages drawbacks metaobject approach building fault-tolerant systems.
