To me personally, this is a typical social spam.

Social Network has its potential value in communication!!


13

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…

Social Network Games

16

Fighter’s Club

• A couple millions users• 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.

Anybody with an IP address

Roughly your friends (or friend2s)

Quality of the Friendship may have been out of control…

A typical politician in Taiwan has about 3K+ FB friends!


19

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.

What we really want:


21

Value of OSN

• How to leverage the value of Online Social Network in Computing/Communication?– Privacy/Confidentiality, Social Ranking

• How to architect the Social Network itself such that its value can be protected?– Trust and Reputation


22

Just a couple controversial points

• Both unique routable identity and global network layer connectivity are unnecessary and considered harmful!– Under OSN, identity is all relative.

• We don’t have globally unique IP addresses and the DNS process itself becomes social.– Less is More!– But, IP addresses and DNS won’t go away any time soon…


23

“Routable Identity”

• Application identity =M=> Network identity

• Network identity =R=> Network identity

• Network identity =M=> Application identity

“App/Route Identity”

• Application identity =M=> Network identity

• Network identity =R=> Network identity• Network identity =M=> Application identity

• Keywords =(MF-R)=> “Multiple Paths”• Application identity selection• Network route selection

The end user will have some control via the social layer!


28

URI versus ADC

• URI (Unique Routable Identity)– We assume that our destination target is bound to an URI.

– We assume that both the MAPPING (e.g., DNS) and ROUTING (e.g., BGP) are correct.

• ADC (Application Dependent Credential)– The lower layer (like search engine) will give us a few options to click.

– The application (or the user) will then choose the one (or ones).

Communication is Mutual

IP access is improving, but social resources connecting to the rest of the world is still behind.

31

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

Communication Dualism


38

OSN Mutual Anonymity

• Blind OSN date, embarrassment-less friendship establishment, Message in the Bottle, Anonymous Confession– Keywords of Interests– Relative Reputation/Trust– “Content-level” Privacy is out of scope

• The communication parties don’t know the identifiers of each other, at least initially, and their exact social relationship

Three Layers

• User Access layer – Native & Existing Applications

• Social Control Layer– The core of DSL

• Network Control Layer– Network Virtualization


41

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.

Re-consider the current Internet architecture

1. Global Connectivity vs. Mutual Interest

2. Unique Routable Identifier vs. Application Dependent Credential

GENI Experiment

• Leverage (and discover) the “features” of ProtoGENI as much as possible for our NSF FIND project.

• Build something on “DSL” that is attractive and usable by real users– feedback to the FIND/GENI community

• Share and reuse the experiments (data traces and models, under IRB)
