1. 1 COAST Consortium Proprietary Content Aware Searching, retrieval and sTreaming in Future Internet Theodore Zahariadis Project Technical Coordinator zahariad@synelixis.com Spring Concertation Meeting Brussels, 4 February 2010 * The COAST logo is based on the painting “Birds Eye View of Sea Coast” by Leonardo Da Vinci

2. 2 COAST Consortium Proprietary Project Summary COAST will focus on 3 innovation pillars: Content & Services Searching & Indexing. Based on intelligent nodes, COAST will –“on the fly” identify/classify content and identify Web services via inspection of the traffic that flows through the nodes (DPI & Signalling Analysis) –discover “on line”, where services are located and content is located/cached (Crawling) Content-Aware Delivery Network Architecture. COAST will –discover the underlying network infrastructure, the user terminal and the user needs –construct content-aware overlays to offer distributed, robust and network-/service- provider friendly content delivery, leading to improved PQoS. Future media content adaptation and enrichment. COAST will provide for scalable, HD 3D/free-viewpoint video with interactive virtual panning/zooming, which will be on-the-fly adapted, enriched and optimized. COAST aims to offer fast content-aware retrieval, delivery and streaming, while meeting network-wide Service Level Agreements (SLAs).
