    1. 1. Overview of the Internet/Broadband RTV 3000 Introduction to Telecommunication
    2. 2. Evolution of the Internet <ul><li>Question posed in 1963 by RAND, a cold war think tank. </li></ul><ul><li>“ How could the U.S. communicate after a nuclear attack?” </li></ul>
    3. 3. Internet Evolution <ul><li>Answer </li></ul><ul><li>The communication network would require: </li></ul><ul><li>The intelligence to reside in the endpoints </li></ul><ul><li>Any endpoint could talk to any other endpoint </li></ul><ul><li>Network Routing be self-healing after attack </li></ul><ul><li>No centralized control </li></ul><ul><li>Messages divided into packets that could take any number of paths from source to destination </li></ul>
    4. 4. Internet Evolution <ul><li>Internet began as ARPANET in the late 1960s, run by Dept. of Defense </li></ul><ul><li>Development of TCP/IP Protocols in mid 1970s, incorporated into ARPANET in 1983 </li></ul><ul><li>NSF supports TCP/IP in CSNET in early 1980s </li></ul><ul><li>ARPANET and CSNET merge in 1980s </li></ul>
    5. 5. Internet Evolution <ul><li>NSF subsidizes NSFNET backbone and regional networks in 1986 </li></ul><ul><li>NSF Phases out federal support for Internet backbone in 1992-95 </li></ul><ul><li>Internet commercialized in mid 1990s </li></ul>
    6. 6. The World Wide Web <ul><li>Created by Tim Berners-Lee in 1991 at the European Center for Nuclear Research (CERN) </li></ul><ul><li>Portion of the Internet that utilizes a software program (browser) to display WebPages </li></ul><ul><li>Browser development: Mosaic in 1993; Netscape Navigator popularized in mid 90s </li></ul>
    7. 7. Internet in Context <ul><li>Internet is convergence </li></ul><ul><li>Unique Multi-modal capabilities and user-driven qualities compared to previous telecommunication technologies </li></ul><ul><li>Many predict shared protocol of the Internet is platform of the future </li></ul>
    8. 8. Brief overview of the Internet <ul><li>Digital data and bits (1’s & O’s) are packet switched on interconnected networks through use of routers and communication links </li></ul><ul><li>Packet-switching involves TCP/IP </li></ul>
    9. 9. Brief overview of the Internet <ul><li>Best efforts routing; packets of related-information (e.g. email) may travel different paths </li></ul><ul><li>Packets reassembled at final destination </li></ul><ul><li>e2e allows for creative applications and software </li></ul><ul><li>Openness key to daisy chaining, e2e & more </li></ul>
    10. 10. Who governs the Internet? <ul><li>No centralized controlling authority </li></ul><ul><li>Standards and protocols set by a number of self-governing organizations, including: </li></ul><ul><ul><li>Internet Society (ISOC) </li></ul></ul><ul><ul><li>Internet Architecture Board (IAB) </li></ul></ul><ul><ul><li>Internet Engineering Task Forces (IETF) </li></ul></ul><ul><ul><li>Internet Corporation for Assigned Names and Numbers (ICANN) </li></ul></ul><ul><li>Existing governing and political institutions may influence policy </li></ul><ul><li>Misnomer to believe Internet is completely unregulated </li></ul>
    11. 11. Internet is convergence <ul><li>Common product/service platform that support multiple functions </li></ul><ul><li>Driven by digitization, bandwidth and throughput </li></ul><ul><li>Form of information carried traditionally by different delivery mechanisms: voice (telephone), data (private corporate network), and video (broadcast network or cable tv) </li></ul><ul><li>Multi-modal content </li></ul>
