Network-Enabled Servers (NES) environments are valuable candidates to provide simple computing grid access. These environments allow transparent access to a set of computational servers via Remote Procedure Call mechanisms. In this context, a challenge is to increase performances by decreasing data tra?c. This paper presents DTM (Data Tree Manager) a data management service for NES environments. Based on the notions of data persistency and data replication, DTM proposes a set of e?cient policies which minimise computation times by decreasing data transfers between the clients and the platform. From the end-user point of view, DTM is accessible through a simple and transparent API. In the remainder, we describe DTM and its implementation in the DIET platform. We also present a set of experimental results which exhibit the feasibility and the e?ciency of our approach.
