2 ARPA Advanced Research Project Agency Also know as DARPA
(Defense Advanced Research Project Agency) 1958 U.S. Department of Defense (DoD) formed ARPA in response to Soviet launch of Sputnik and the fear of Soviet domination of space.

3 ARPANET Advanced Research Project Agency Network Developed to:
Exchange data between research and government agencies Withstand catastrophic damage (hurricanes, nuclear strike, etc.) Interconnect different types of networks First nodes: Aug 1969 – University of California Los Angeles (UCLA) Oct 1969 – Stanford Research Institute (SRI) Nov 1969 – University of California Santa Barbara (UCSB) Dec 1969 – University of Utah #2 SRI #4 Utah #3 UCSB #1 UCLA

4 NCP Network Control Protocol
1970 – Completed the first Host-to-Host protocol used by ARPANET (called NCP) NCP was based on the new and powerful concept of packet switching.

5 @ 1971 – First application was written by Ray Tomlinson at BBN Technologies 1972 – Tomlinson upgraded and released user-friendly application 1973 – accounts for 75% of ARPANET traffic BBN – Bolt, Beranek and Newman; the last names of the three founders of BBN Technologies

6 TCP/IP Transmission Control Protocol/Internet Protocol
1973 Developed to replace NCP 1978 Internet Protocol version 4 (IPv4) released 1983 TCP/IP Implemented as ARPANET standard TCP/IP architecture was first proposed by Bob Kahn at BBN and further developed by Kahn and Vinton Cerf and others at Stanford Vinton Cerf was involved in much of the development of the Internet as has been called “The father of the Internet”

7 UNIX version 4.2BSD UNIX is a derivation of UNICS – UNIplexed Information and Computing System (UNICS is a pun on its predecessor MULTICS - Multiplexed Information and Computing System – Unix was not originally envisioned to be a multi-tasking operating system) 1983 – The Berkley Software Distribution version of UNIX was released (UNIX 4.2BSD) 4.2BSD incorporated support for TCP/IP

8 DNS Domain Name System A global directory structure to resolve IP addresses to domain names 1985 – DNS started Six large domains were named: edu (education) gov (government) mil (military) com (commercial) org (organization) net (network resources).

9 NSFNET National Science Foundation Network
1986 – National Science Foundation created high speed Internet backbone (56Kbps)

10 Internet 1990 – ARPANET name is dropped and replaced with Internet.

11 WWW World Wide Web 1991 – WWW Released by CERN
CERN (Conseil Europeen pour le Recherche Nucleaire) is an international research institute in Geneva, Switzerland Tim Berners-Lee developer

12 InterNIC Internet Network Information Center
1993 – InterNIC was created to provide Internet domain name registration services

13 Mosaic 1993 – First web browser Allowed GUI browsing of the Internet
Freeware

14 ISOC Internet Society 1992 – Founded as the umbrella Internet organization. 1995 – Took over control from U.S. Government Non-governmental organization, made up of more than 100 organizations and thousands of individuals Its international mission to foster global cooperation and coordination on Internet technologies It serves as a global clearinghouse for Internet related information

15 ICANN Internet Corporation for Assigned Names and Numbers
1998 – Assumed management of domain names and addresses, DNS, and protocols Includes three supporting organizations: ASO – Address Support Organization DNSO – Domain Name Support Organization PSO – Protocol Support Organization The actual registration is of domain names is performed separate organizations (Registrars)

16 IP (IPv6) 2000 – Internet Protocol version 6 (IPv6) deployed on Internet backbone Improvement include: Increases the number if IP addresses Improved routing capabilities Network autoconfiguration Designed to coexist with IPv4
