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

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

The emails I received typically…

To me personally, this is a typical social spam.

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…

Don’t worry about the language…

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.
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 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.

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

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

The Social Path(s)
44
Community
• A connected graph of social nodes sharing a set of community attributes

Community Control:

Who should receive the keyword announcement for “wu@cs.ucdavis.edu”? Answer: Who should receive the keyword announcement fot “South Lake Tahoe Tournament”? Answer:

as the Social Peer
• Attributes:– {McDonald’s Express, 640 W Covell Blvd, # D, Davis, (530) 756-8886, Davis Senior High School, Community Park, North Davis}
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 L1
– [>=0, , ] K via L2

Scalability & Controllability
• McDonald’s doesn’t 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

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.
