2 2 SMTP SMTP as an example… Its about communication between two networked entities…

3 3 Internet SMTP

4 4 Internet Architecture & Routing Any identity ( address, IP, url) can communicate with any one else. – , web, bittorrent, warcraft, skype…

5 5 The s I received typically…

6 6 You have a few seconds to decide……

7 7 To me personally, this is a typical social spam.

8 8 Oops…

17 17 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…

18 18 Dont worry about the language…

20 20 Fighters 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.

21 21 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 didnt 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.

22 22 Friendship requested

23 23 Friendship requested BTW, this guy stole 24 millions dollars from me during my DSL demo to George Kesides!

24 24 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…

40 40 Just a couple issues … How to establish the social route? –How would A know about D (or Ds identity) ? How to maintain this reputation network? –KarmaNet: A Feed-back Trust Control System

43 43 The Social Path(s)

44 44 Community A connected graph of social nodes sharing a set of community attributes

45 45 Community Control: C D Who should receive the keyword announcement for Answer: Who should receive the keyword announcement fot South Lake Tahoe Tournament? Answer: E

46 46 as the Social Peer Attributes: –{McDonalds Express, 640 W Covell Blvd, # D, Davis, (530) , Davis Senior High School, Community Park, North Davis}

47 47 Per-Keyword Policy 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) –A: Community Attributes Examples: –[>0.66, 4, Davis] K via L 1 –[>=0,, ] K via L 2

48 48 Scalability & Controllability McDonalds doesnt want to flood the whole network –It only wants to multicast to the Target set of customers And, it only wants this target set of users being able to use that particular keyword to contact. –Receiver/owner controllability

55 55 http Anybody with an IP address Roughly your friends (or friend 2 s) Privacy as social values

56 56 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. AB AB F F F And, I certainly dont have the answer yet…
