The active networking paradigm corresponds to an initiative including projects, developments and implementations searching for a new communication concept/ paradigm allowing fast, safe and efficient communications. The basic target is to provide, among other features and services, the management and configuration of new and complex network services and equipment (backbones), supporting dynamically the quality of service (QoS) needs of the new multimedia applications, so often pointed as the trend in the web world. This paper evaluates experimentally and objectively the usability of a specific active networking implementation architecture (ANTS) focusing on the dynamic configuration of backbone routers for supporting QoS in a multimedia applications scenario. The paper describes the evaluated architecture, proposes two implementation scenarios and evaluates experimentally their use for dynamic routers configuration., {"references":["Tennenhouse, D.
