Next generation e‐learning platforms will support cooperative use of geographically distributed educational resources as an aggregated environment, thus enabling a more effective knowledge exchange. Sharing this goal, our research activity addresses the definition and implementation of a service‐based infrastructure for content distribution and multimedia streaming. The proposed architecture provides enough flexibility, extensibility, and scalability to cope with the ever‐increasing heterogeneity and mobility of edge devices. In this paper, we initially illustrate the general objectives and requirements in the development of an e‐learning oriented application for multimedia content discovery, access, and distribution in a virtual community. Architectural considerations have motivated the use of Grid technologies as they provide access to resources and services of different administrative domains in a transparent, seamless, and secure way. The Grid‐based architecture has been endowed with a number of services including discovery and streaming of multimedia objects, multimedia content update, quality of service (QoS) management, and support for user authentication and authorization. A multimedia application based on the architecture is described and evaluated on a multi‐domain network. Copyright © 2005 John Wiley & Sons, Ltd.
