3. Abstract • The CCN paradigm perfectlyfits with the OSN applications behavior and canhelp to save network load and reduce latency. • The benefit of using such aCCN approach compared to the current classical IP-based delivery and to the CDN-basedsolution, for the use-case of Twitter.

4. Concept of ICN • Focus on the content the user wishes to obtain instead of the server that provide this content. • Content should be named in such a way as to be independent of the location of the node where the content can be found • Nodes can cache the contents passing through it for a while.

5. Content Centric Networking Interest message: send for content which user is interested Data message: returned back to user as respond PIT: pending interest table FIB: forwarding information base

12. Conclusion • Resulting from our evaluations, using ICN for social networking applications is advantageous for the network operator as expected but also for the end users QoE (Quality of Experience) • We plan to develop/adapt an OSN application on top of the CCN solution, to better suit native ICN functions and make large-scale tests on a real network

13. 每週一句 • Nowadays, Internet is becoming a large repository of contents whose main providers are music, video or webTV streaming services.
