  1. Introduction to TCP/IP Networks

  2. Chapter Objectives • Understand what TCP/IP • Understand scope of TCP/IP networks • Explore classroom network setup • Understand the Internet

  3. Introduction to TCP/IP Networks scope of TCP/IP networks Origins of TCP/IP networks Multivendor Support Classroom Network The Internet TCP/IP Application Services

  4. What is TCP/IP??

  5. What is TCP/IP(continued)

  6. What is TCP/IP(continued)

  7. The Defense Advanced Research Projects Agency (DARPA) Requirement • In the late 1960s, DARPA noticed the following trends: - Rapid proliferation of computers in military communications - Deployment of multivendor equipment in communication networks • The U.S. Department of Defense (DoD) mandated a common set of protocols - Advantages are -- Procurement simplification -- Competition -- Interoperability -- Vendor productivity and efficiency • As a result of DoD efforts, the ARPAnet was formed, which later evolved into the Internet

  8. The Internet community • Earlier Internet community consisted of - Universities -- Stanford, UCLA, Massachusetts Institute of Technology (MIT) -- UCSB -- University of Utah, University of Hawaii - Research organizations -- SRI International, Rand Corporation -- The Institute of Advanced Computation -- Bolt, Beranek, and Newman (BBN) • Current Internet Community includes • All major universities • Research organizations • Corporations • Individual users

  9. Introduction to TCP/IP networks Scope of TCP/IP Networks Origins of TCP?IP Networks Classroom Networks Multivendor Support The Internet TCP/IP Application Services

  10. Proprietary Networks • Early commercial computer network - Proprientary solutions -- Examples: IBM’s SNA, DEC’s DECnet - Locked users to vendor platform

  11. Proprietary Networks (continued)

  12. Commercial Uses of TCP/IP

  13. Driving Force Behind TCP/IP Support • Currently, the driving force behind TCP/IP support is - Growth in network-management tools - Promise of interoperability - Commercialization of the Internet • Most widely implemented network-management protocol is - Simple Network Management Protocol (SNMP) -- Makes use of TCP/IP protocols

  14. Introduction to TCP/IP Networks Scope of TCP/IP Networks Origins of TCP/IP Networks Classroom Networks Multivendor Support The Internet TCP/IP Application Services

  15. TCP/IP Applications • A few popular application-level services are - Terminal emulation (TELNET) - File Transfer Protocol (FTP) - Simple Mail Transfer Protocol (SMTP) - Network File System (NFS) - Simple Network Management Protocol (SNMP) - Domain Name System (DNS)

  16. TCP/IP Applications (continued)

  17. Application Services Chart

  18. Introduction to TCP/IP Networks

  19. Classroom Network Configuration: 10Base-T Ethernet

  20. Workstation Configuration: UNIX and DOS

  21. Classroom Hosts and Servers

  22. Software Tools for TCP/IP Applications Services • For Unix workstations - Unix with TCP/IP software • Protocol analysis tool - LANWATCH from FTP Software • For DOS workstations • WinQVT from QPC Software • NCSA TELNET and FTP protocols • PC/TCP from FTP Software • Son Of Stan Server (SOSS) • NetManage’s Chameleon

  23. Hands-On Exercise 1.1: Warm-Up • Your instructor will guide you to Hands-On Exercise 1.1 in the Exercise Manual

  24. Introduction to TCP/IP Network

  25. TCP/IP Time-Line Evolution

  26. Internet Examples

  27. Introduction to TCP/IP Networks

  28. Structure of Internet Activities Board (IAB)

  29. RFCs and IENs

  30. Vendors’ TCP/IP implementations should comply with the Official Protocol Standart Practical experience suggests that vendors are not 100 percent compliant May have interoperability problems between vendors’ TCP/IP implementations --Differences in interpretation of standards --Willful ignoring of standard recommendations This course and other courses in the TCP/IP curriculum will emphasize vendor-specific issues by using the following icon: TCP/IP Implementation Concerns

  31. Chapter Summary You have learned • What TCP/IP is • The scope of TCP/IP networks • The classroom network setup • About the Internet
