Slide 3Consultation Workshop, Brussels, 19th Jan 2010
Content mediation for efficient traffic distributionChallenges
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

PHYSICAL NETWORK: SCALABILITY & STABILITY
IMPLICATIONS:o Maximum BW & Users with minimum costo Minimum number of IDs and rules (aggregation)
IMPLICATIONS:o Interface as simple as possibleo Flexible identificationo Help to search capabilitieso 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???
