  1. The Internet Definition Applications Growth

  2. A Definition • On October 24, 1995, the FNC unanimously passed a resolution defining the term Internet. • RESOLUTION: The Federal Networking Council (FNC) agrees that the following language reflects our definition of the term "Internet"."Internet" refers to the global information system that -- • (i) is logically linked together by a globally unique address space based on the Internet Protocol (IP) or its subsequent extensions/follow-ons; • (ii) is able to support communications using the Transmission Control Protocol/Internet Protocol (TCP/IP) suite or its subsequent extensions/follow-ons, and/or other IP-compatible protocols; and • (iii) provides, uses or makes accessible, either publicly or privately, high level services layered on the communications and related infrastructure described herein.

  3. History of the Internet Mid 1960: Papers on “Packet Switching” emerge. End 1969s: ARPA sponsors the development of a packet-switching network, called the ARPANET. First four nodes are UCLA, SRI, U. Utah, UCSB. 1974: The TCP/IP protocols and model are being proposed by Cerf/Kahn. 1983: ARPANET adopts TCP/IP. At this time, the ARPANET has 200 routers. 1984: NSF funds a TCP/IP based backbone network. This backbone grows into the NSFNET, which becomes the successor of the ARPANET. 1995: NSF stops funding of NSFNET. The Internet is completely commercial.

  4. Applications of the Internet • Traditional core applications:Email News Remote Login File Transfer • The killer application:World-Wide Web (WWW) • Future applications:Videoconferencing and Telephony Multimedia Services Internet Broadcast

  5. Time Line of the Internet Source: Internet Society

  6. Growth of the Internet • Number of Hosts on the Internet: Aug. 1981 213 Oct. 1984 1,024 Dec. 1987 28,174 Oct. 1990 313,000 Oct. 1993 2,056,000 Apr. 1995 5,706,114 Oct. 1999 105,656,154 (projected)

  8. Who’s Who on the Internet ? • Internet Engineering Task Force (IETF): The IETF is the protocol engineering and development arm of the Internet. Subdivided into many working groups, which specify Request For Comments or RFCs. • IRTF (Internet Research Task Force):The Internet Research Task Force is a composed of a number of focused, long-term and small Research Groups. • Internet Architecture Board (IAB): The IAB is responsible for defining the overall architecture of the Internet, providing guidance and broad direction to the IETF. • The Internet Engineering Steering Group (IESG): The IESG is responsible for technical management of IETF activities and the Internet standards process. Standards. Composed of the Area Directors of the IETF working groups.

  9. Who’s Who on the Internet ? • Internet Society (ISOC): The Internet Society is a professional membership organization of Internet experts that comments on policies and practices and oversees a number of other boards and task forces dealing with network policy issues. • Federal Networking Council: The FNC's 18-member board includes representatives from the National Institutes of Health, the Department of Energy and the National Science Foundation, among other federal agencies. • Internet Assigned Numbers Authority (IANA): Based at the ISI, IANA is in charge of all "unique parameters" on the Internet, including IP (Internet Protocol) addresses. • InterNIC: Formed in January 1993, the InterNIC (Internet Network Information Center) is a collaborative project for management of the Internet domain name data base and registration process.

  10. Internet Standardization Process • All standards of the Internet are published as RFC (Request for Comments). But not all RFCs are Internet Standards ! • A typical (but not only) way of standardization is: • Internet Drafts • RFC • Proposed Standard • Draft Standard (requires 2 working implementation) • Internet Standard (declared by IAB) • David Clark, MIT, 1992: "We reject: kings, presidents, and voting. We believe in: rough consensus and running code.”
