Research on dynamic updating of grid service

Abstract

In complicated distributed system based on grid environment, the grid service is inadequate in the ability of runtime updating. While in the maintenance of systems in grid environment, it is an urgent issue to solve to support the transparent runtime updating of the services, especially in the case of services communicating with each other frequently. On the basis of researches on the implementation of grid services and interaction between them following WSRF [3], this paper introduces proxy service as the bridge of the interaction between services and achieved the ability to support the runtime dynamic updating of grid services. Gird service updating must happen gradually, and there may be long periods of time when different nodes run different service versions and need to communicate using incompatible protocols. We present a methodology and infrastructure that make it possible to upgrade grid-based systems automatically while limiting service disruption. © Springer-Verlag Berlin Heidelberg 2007.
