SMTP as an example…
It’s about communication between two networked entities…

The value of the “Social Network”
• Social Network has its own unique value in facilitating human communication
• A concern about a network losing its “value”– while we are unsure about how to quantify the true value…

Fighter’s Club
• A Coalition game ~ like Warcraft• Team members who are Facebook friends receive higher fighting powers
• ~1400 new friendships established daily
• ~10% of users with >95% friendships purely based on this game.

Open Issues
• What is the “value” of this social network?
• How would this “value” be distributed and allocated to each individual peers?
• MySpace, Facebook, LinkedIn didn’t define the “game” for network formation and value allocation.– But, it is important to design the game such that the OSN will eventually converge to a state to best support the communities.

Research Issues
• How to systematically leverage the Social Network?
• How to architect the Social Network itself such that its value can be protected?
• And, plus a few typical CS concerns– Decentralization, Scalability, Privacy/Trust…

• For each keyword, we will associate it with a propagation policy: [T, N, A]– T: Trust Value Threshold– N: Hop counts left to propagate (-1 each step)

Scalability & Controllability

DSL is an old idea!
We, as human, have been using similar social communication principles. Maybe it is a good opportunity to re-think about our cyber communication system.
Identity is a per-application, context-oriented, and sometime relative issue.
Forming cyber communities of interests for application.
