The rapid development of the Internet and its increasing popularity required a refinement of communication paradigms which represented the de facto standard a few years ago. A scalable modern network consists of hundreds or thousands of clients which exchange data with each other without a required central authority. This architecture introduces new problems and difficulties. One of these problems is the need of data replication in a highly scalable, distributed environment. This work introduces a replication mechanism for MozartSpaces, which follows the space based computing approach.
