2 TELEFÓNICA I+D Growing bandwidth needs From machine access to content access Growing proliferation of Internet multimedia content: Traditional contents being transferred to the Internet Surge of prosumers QoE expectations for Internet media approaching to traditional media Slide 2 Consultation Workshop, Brussels, 19th Jan 2010 Content mediation for efficient traffic distribution Rationale

3 TELEFÓNICA I+D Slide 3 Consultation Workshop, Brussels, 19th Jan 2010 Content mediation for efficient traffic distribution Challenges CURRENT SITUATION Contents are fragmented (variety of platforms & search engines) QoS mechanisms are local and dependant on access technology Multicast is only intra-domain (not Internet-wide) Lack of standards for content distribution Corporate providers: High transaction costs to change CDN Casual publishers (prosumers): High entry barriers for efficient distribution DESIRABLE SITUATION Integrated content space (one platform & search engine… … but multiple retrieval possibilities) End-to-end QoS Multicast available at Internet scale (inter-domain) Internet oriented to content distribution

4 TELEFÓNICA I+D Content mediation for efficient traffic distribution Requirements Slide 4 Consultation Workshop, Brussels, 19th Jan 2010 USER VIEW: FLEXIBILITY PHYSICAL NETWORK: SCALABILITY & STABILITY IMPLICATIONS: o Maximum BW & Users with minimum cost o Minimum number of IDs and rules (aggregation) IMPLICATIONS: o Interface as simple as possible o Flexible identification o Help to search capabilities o A huge amount of IDs and information (disaggregation) BUILDING BLOCKS: Local QoS & Multicast Evolution of basic network services (DNS, RADIUS, LDAP) Contradiction between both worlds???
