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

  2. Project Summary COAST aims to offer fast content-aware retrieval, delivery and streaming, while meeting network-wide Service Level Agreements (SLAs). 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. • Futuremedia 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.

Caching Caching DIP DIP Adaptation Adaptation Routing Routing 1: Crawling & Searching Preparation Query Processor Local Cache Crawler Indexer Active Crawling Regular Data Delivery In-node/overlay information Passive Crawling Content Server 1 Content/Service Prosumer A Content/Service Prosumer C Content/Service Prosumer B

  7. Crawling based on: • Deep Packet Inspection • Identification of Digital Object Identifier (DOI), RFC 3651 • Identification of video fingertip • Identification of simple patterns • Services based on the RESTfull paradigm • Signalling Analysis • Analysis of SDP /RTSP set-up messages • Retrieve Content Characteristics • ID/ownership • Type, encoding, size, fps, video quality, jitter • Popularity • Potential Caching location

  10. Context/Network Based Adaptation • Select different video location/cache • Select different video • Select/create different streaming path • Select/create different P2P overlays (multiple trees vs mesh) • Select based on user terminal/location • Select based on network type/quality/congestion • Adapt content quality (HD 3D to QCIF 2D) • On-the-fly free/multi-view, 3DV and interactive interactive zooming/panning
