Introduction To Networks

  1. 1. Introduction To Networks Using Linux NAD710 Linux Lab Series Professor: Tom Mavroidis
  2. 2. The Internet <ul><li>Never has there been such dramatic changes to the business world as we have seen in the 1990’s with e-business and the internet. </li></ul><ul><li>The role played by internet has forced companies to get connected to stay relevant so they may compete in today's fast moving markets. </li></ul>
  3. 3. TCP-IP and The Internet Model <ul><li>In the 60’s and 70’s there were many different networks, protocols and implementations. </li></ul><ul><li>Sharing of information among these dissimilar networks soon became a problem. </li></ul><ul><li>A common protocol needed to be developed. </li></ul>
  4. 4. DARPA <ul><li>The Defense Advanced Research Projects Agency funded the exploration of this common protocol. </li></ul><ul><li>The TCP/IP protocol suite evolved from the ARPANET protocol suite where the fundamental concept of layering was introduced. </li></ul>
  5. 5. Backbone Protocol <ul><li>TCP/IP became the backbone protocol of multivendor networks such as ARPANET, NFSNET and other regional networks. </li></ul>
  6. 6. Historical Maps of ARPANET <ul><li>Paul Baran in the 1960s envisioned a communications network that would survive a major enemy attacked. The sketch shows three different network topologies described in his RAND Memorandum, &quot;On Distributed Communications: 1. Introduction to Distributed Communications Network&quot; (August 1964). The distributed network structured offered the best survivability. </li></ul>
  7. 7. <ul><li>On the battlefield a communications network will sustain damage, so the DOD designed TCP/IP to be robust and automatically recover from any node or phone line failure </li></ul>
  8. 8. University of California at Berkeley <ul><li>The protocol suite became popularized when it was integrated into the University of California at Berkeley’s UNIX operating system and became available to the public at a nominal fee. </li></ul>                                                                                                                                                                     
  9. 9. TCP/IP <ul><li>TCP/IP provides the ability to merge different physical networks using a common suite of functions and interoperability between equipment. </li></ul>
