Abstract

Object replication and caching have been used individually in distributed systems for many years. There are benefits from being able to support both: replication for availability, and caching for performance. Although both involve handling multiple copies of objects, there are sufficient differences between the two to make the design of an integrated approach a challenging exercise. In this paper we shall describe a design that provides the benefits of both replication and caching by allowing both types of protocols to co-exist within the same application. We do not propose a new replication or caching protocol; rather a way in which existing implementations can be combined.
