Concertation Meeting, Brussels, 3rd February 2010Slide 6© COMET COMET aims to provide a unified interface for content access whatever the content characteristics are: –temporal nature (pre-recorded or live), –physical location (centralised or distributed), –interactivity requirements (elastic or real-time), or –any other relevant features It also aims to apply the most appropriate end-to-end transport strategy: –By mapping the content according to its requirements and user preferences to the appropriate network resources best quality of experience for end users –All different types of content distribution will be supported: Unicast, anycast, multicast… The COMET project Top-level objectives … while preserving network availability and structural resilience, as key factors in perceived QoE
