Abstract

Replication provides high performance and availability but introduces the problem of data consistency that arises when replicas are modified. Session guarantees may be used to manage replica consistency of a distributed system from a migrating client's perspective. This paper presents and proves safety of a new consistency protocol of session guarantees using object-based version vectors.
