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