Technical Information Technology Assessment of Middleware for Telecommunications White Paper on Middleware Platforms Scalability and Dependability Authors: Sune Jakobsson (editor), Erik Berg, Telenor AS Bertrand Mathieu, Yvon Gourhant, Remi Kerboul, France Télécom Marcin Solarski, Christian Egelhaaf, GMD Fokus/Deutsche Telekom AG Abstract This white paper presents the main findings, summaries and excerpts from the experiments carried out in the tasks on scalability and dependability in the EURESCOM project P910 on “Technology Assessment of Middleware for Telecommunications”. Scalability and dependability are important requirements on a middleware system. Since these requirements have some common aspects, they are presented together in this document. The document covers theoretical studies and practical experiments with middleware from different vendors and research groups, with the focus on scalability and dependability. The document assumes that the reader has some basic knowledge of a distributed middleware based system. EDIN 0096-0910 Project P910 For full publication April 2001
