How did the Internet come to
be?
It started as a research project to
experiment with connecting computers
together with packet switched networks.
It was developed with funding and
leadership of the Defense Departments
Advanced Research Projects Agency
(ARPA).
-3
Who invented the Internet?
Al Gore? No 
Leonard Kleinrock who did early work in
packet switching?
Vint Cerf and Robert Kahn who defined the
"Internet Protocol" (IP) and participated in
the development of TCP?
Tim Berners-Lee who developed HTTP to
support a global hyper-text system he
called the World Wide Web? (Internet vs
the World Wide Web?)
-4
1958-1961: Connect Computers?
1958  After USSR launches Sputnik, first
artificial earth satellite, US forms the Advanced
Research Projects Agency (ARPA), the following
year, within the Department of Defense (DoD) to
establish US lead in science and technology
applicable to the military
1961  First published work on packet switching
(Information Flow in Large Communication Nets,
Leonard Kleinrock, MIT graduate student)
1964  other independent work in packet switching
at RAND Institute and National Physics
Laboratory in England
-5
1966 1968: Connect
Computers? Funded
1966  Lawrence Roberts (colleague of
Kleinrock from MIT) publishes overall plan
for an ARPAnet, a proposed packet switch
network
1968  ARPA awards contracts for four
nodes in ARPANET to UCLA (Network
Measurement), Stanford Research
Institute (Network Information Center),
UCSB (Interactive Mathematics) and U
Utah (Graphics); BBN gets contract to
build the IMP switches
-6
1969: First Connections
4/7/1969  First RFC (Host Software by
Steve Crocker) basis for the Network
Control Protocol(NCP)
9/2/1969  Leonard Kleinrocks computer
at UCLA becomes first node on the
ARPANET
10/29/1969  First packets sent; Charlie
Kline attempts use of remote login from
UCLA to SRI; system crashes as G in
entered
-7
1967-1971: So what do we do
with it?
1967-1972  Vint Cerf, graduate student in
Kleinrocks lab, works on application level
protocols for the ARPANET (file transfer
and Telnet protocols)
1971 - Ray Tomlinson of BBN writes email
application; derived from two existing: an
intra-machine email program (SENDMSG)
and an experimental file transfer program
(CPYNET)
-8
1971-1973
Networks Growing
1970 - First cross-country link installed by
AT&T between UCLA and BBN at 56kbps
Other networks: ALOHAnet (microwave
network in Hawaii), Telenet (commercial,
BBN), Transpac (France)
1973  Ethernet was designed in 1973 by
Bob Metcalfe at Xerox Palo Alto Research
Center (PARC)
How do we connect these networks
together?
-9
1972-1974: Protocol
Development
1972-1974  Robert Kahn and Vint Cerf
develop protocols to connect networks
without any knowledge of the topology or
specific characteristics of the underlying
nets
1972  Robert Kahn gives first public
demonstration of ARPAnet (now 15 nodes)
at International Conference on Computer
Communication
-10
1974-1978: Development of
TCP/IP
1974  First full draft of TCP produced
November 1977 - First three-network
TCP/IP based interconnection
demonstrated linking SATNET, PRNET and
ARPANET in a path leading from Menlo
Park, CA to Univ. College London and back
to USC/ISI (Marina del Ray, CA)
1978  TCP split into TCP and IP
-11
1981 1984:
Base Protocols In Place
1981  Term Internet coined to mean
collection of interconnected networks
1982  ISO releases OSI seven layer
model; actual protocols die but model is
influential
1/1/1983  Original ARPANET NCP was
banned from the ARPANET and TCP/IP was
required
1984  Cisco Systems founded
-12
1983-1986: Not Just a
Research Project Anymore
1984  Domain Name System introduced;
1000+ hosts (200 hosts by end of 1970s;
over 100000 by end of 1980s)
1986  NSFNET created to provide access
to 5 super computer centers including
Theory Center at Cornell (NSFNET
backbone speeds 56 Kbps)
1983  ARPANET split into ARPANET and
MILNET; MILNET to carry defense
related traffic
-13
1988-1989: Growing Pains?
1988 - Nodes on Internet began to double
every year
November 1988  Internet worm affecting
about 10% of the 60000 computers on the
Internet (Robert Morris, Cornell)
1988 - Internet Assigned Numbers
Authority (IANA) established in December
with Jon Postel as its Director. Postel was
also the RFC Editor and US Domain
registrar for many years
-14
1990-1993:
WWW Explosion
1990  ARPANET ceases to exist
1990  Tim Berners-Lee develops
hypertext system with initial versions of
HTML and HTTP and first GUI web
browser called WorldWideWeb
1993  Mosaic, a GUI web browser, written
by Marc Andreessen and Eric Bina at NCSA
takes world by storm (showed in-line
images and was easy to install);
WWW proliferates at a 341,634% annual
growth rate of service traffic
-15
1990-1993: Ready for Public
Consumption
1990  First ISP world.std.com
1991  NSFNET lifted restrictions on use
of NSFNET for commercial purposes
1992  Internet Society founded
1993  InterNIC created by NSF to
provide Internet services; Private
companies transition into roles (AT&T 
directory and database services; Network
Solutions  registration services; CERFnet
 information services)
-16
1995: As we know it
1995- NSFNET reverts back to a research
network. Main US backbone traffic now
routed through commercial internet
service providers
1995  Sun launches Java
1995 - Traditional online dial-up systems
(Compuserve, America Online, Prodigy)
begin to provide Internet access
1995 - Registration of domain names no
longer free
-17
How to make the Internet
better?
????????????????????????
-18
Vint Cerf: Open Challenges
Vint Cerf: My primary disappointment has
been the slow pace of high speed access
for residential customers and the demise
of so many competitive local exchange
carriers (CLECs) in the US. The second
area of disappointment is the slow uptake
of version 6 of the Internet protocol
(IPv6). Perhaps the third area is the
continuing difficulty caused by viruses,
worms and distributed denial of service
attacks.
-19
Tim Berners-Lee: Making the
Internet Better
Tim Berners-Lee: Nothing can be perfect, but the
Web could be a lot better. It would help is we had
easy hypertext editors which let us make links
between documents with the mouse. It would help
if everyone with Web access also had some space
they can write to -- and that is changing nowadays
as a lot of ISPs give web space to users. It would
help if we had an easy way of controlling access to
files on the web so that we could safely use it for
private, group, or family information without fear
of the wrong people being able to access it.

  • #9: Initial ARPAnet was a single closed network to communicate with an ARPA host one had to be attached to another ARPAnet IMP
  • #10: NCP first host to host protocol To get things moving Research and Development on the right replacement
  • #13: : Open up to academics worldwide for real work
  • #14: 1989 Link between Australias AARNET and NFSNET 1989 was this first link outside US no? Link to univ college London?
