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).

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
