Generic support for caching and disconnected operation

Current systems use caching to provide high performance and possibly support disconnected operation. However, current solutions are type specific. With the advent of modular distributed operating systems and mobile machines there is a need to provide generic support for implementing cacheable/disconnectable services. We present an architecture that can be used to implement cacheable/disconnectable services of any type. In addition we present the implementation of this architecture on the Spring operating system. We have used this architecture for implementing file caching and are currently working on other caching implementations and providing support for disconnected operation
