An interceptor-based CORBA object proxy caching system

Next-generation distributed CORBA applications and services must be flexible, reusable, and capable of providing scalable, low-latency quality of service (QoS) to delay-sensitive applications. Caching is an important technique to improve performance for critical and real-time distributed applications. In this paper, we provide a unified object caching architecture (based on caching proxies that use interceptors), easily extendable to mobile system. This approach is based on write-through-invalidate cache consistency policy, per-process caching, object-graph based data shipping and replication management. We apply our architecture on applications with various system requirements (e.g. strong/casual consistent and read-only system) and make a comparison among them. We demonstrate that the proposed approach of caching results in a significantly improved performance for applications that exhibit a reasonable amount of locality and read operations.
