Simplicity of the Internet
● Core of the Internet: TCP/IP● TCP: end-to-end protocol
– Reliable transfer between end devices
● IP: inter-networking protocol– Relaying over different intermediate subnetworks
● End-to-End Principle– Complex TCP with Simple IP

End-to-End (e2e) Principle
● Intelligence at the edges, not in the network● Smart hosts, simple relays(routers)● TCP: complex
– Reliability; error recovery by retransmission
● IP: very simple– Only for relaying, nothing else
● “Connectivity is its own reward”– Connection is all that matters.

No Quality of Service (QoS)
- no error recovery > no reliability - no guaranteed bandwidthNo security
Just “Best Effort”

What was before e2e?
● Telephone Network– Complex/huge/intelligent network
– Dummy terminal(phone set); nothing but dialing
● Who's in control?– Network or Edge?
● Collision of industries: Telecom vs Computer– Like those of civilizations, religions, ideologies

KISS: Keep it Simple and Stupid!
● There're many good sides of simplicity.– Immediate convenience though often caotic
– Why do you prefer cars to trains?
● The Internet thrives on simplicity.● Perhaps, too simple/stupid?
● Make everything as simple as possible, but not simpler. - Einstein -

We Want More!
● QoS– Guaranteed bandwidth
– Bounded delay & jitter
● Security– Inherent, not as an add-on
– Privacy
● More ...

NGI: Next Generation Internet
● 90's ~ 2005● All kinds of patches
– Int-Serv/Diff-Serv, IPSEC, Mobile IP, multicast, ...

Future Internet
● Clean Slate● Revolution than Evolution● Innovation than Renovation● Backward compatibility
– Desirable but not a requirement

Some FI Buzz Words
● DTN: Delay/Disruption Tolerant Network– Remote villages, inter-plenary
● CCN: Content-Centric Network– Telecom: (phone) numbers
– Internet: (IP) address
– CCN: (content) ID
● SDN: Software-Defined Network– Dynamically configurable, Polymorphic

Internet & Future Internet
● Internet: championed by students– TCP/IP: Vint Cerf & Bob Kahn
– Mosaic/Netscape: Marc Andreessen
– Facebook: Mark Zuckerberg
– Yahoo, Google, YouTube, Twitter, ....
● Future Internet– Any reason to be different?
– Which do you believe in, Samsung or Yourself?
