This paper describes and analyses a solution to the problem of data synchronization and replication for distributed entities such as directories in IP communication networks. We discuss the role of directories in the developing IP communications service infrastructure. The data replication solution we have implemented is based on the protocol specifications for the Internet, titled `Server Cache Synchronization Protocol' (SCSP). We review the requirements of using and maintaining data that is shared among many applications while the data resides in different physical locations. We give a brief description of the SCSP and discuss its implementation. We point out some possible applications for the protocol in a mixed IP/ISDN network. We also review some alternative approaches to directory services. In conclusion we propose the SCSP as a component for directory enabled networks--a concept emphasizing the key role of directories in the merging communications infrastructure. New emerging services manage large amounts of data. To facilitate the data management it is distributed over different locations following directory structures where the information is close to the customer location. The main goal is to achieve a global service accessible from everywhere, independently of the location where the user is accessing the service.
