  4. What is This Course about? • Understanding how TCP/IP is implemented in real systems by • Studying the design and implementation in a popular system (Linux) • Hands-on project • Getting some sense of general networking research issues by • Paper reading and critique FSU CIS 5930 Internet Protocols

  5. Course Prerequisites • Two key prerequisites • Familiar with TCP/IP protocol and general networking concepts • CEN5515 Data and Computer Communications or equivalent courses • Comfortable with Unix/C programming • COP5570 Advanced Unix Programming or equivalent courses • Talk with me if you are not sure. • Willing to learn and work hard FSU CIS 5930 Internet Protocols

  10. Important Dates Email Subject: CIS 5930, assignment ID/project phase FSU CIS 5930 Internet Protocols

  11. Four Homework Assignments • First: architectural principles of Internet, 3 papers • Second: routing table lookup, 3 papers • Third: general routing issues, 4 papers • Fourth: overlays and peer-to-peer systems, 4 papers • All papers are online. Read early • Some guidelines on the report • Up to two pages • What are the main points of the papers • What do you like/dislike the paper • If you work on the same subject, what you may do to improve the paper? • Inspirations from the papers • Others FSU CIS 5930 Internet Protocols

  12. The Project • Phase 1: transparent bridges, IP, ARP, UDP • Phase 2: TCP, OSPF • Some guidelines on the report • What components/functionalities you have implemented • Briefly describing the main functions • Journey of the implementation, what you do first, second, etc. • Difficulties encountered and how you solve them FSU CIS 5930 Internet Protocols

  13. The Project (Cont’d) • Now, let us talk about the project • Link to the project FSU CIS 5930 Internet Protocols

  14. Three network components • Stations • End user systems, like your workstation/PC • Sending/receiving packets • Routers • Forwarding data packets • Bridges • LAN device connects routers/stations on the same LAN. FSU CIS 5930 Internet Protocols

  15. Network emulations • Stations/routers/bridges are all software-based. • Physical links/medium are emulated using a reliable TCP connection FSU CIS 5930 Internet Protocols

  16. Emulations • Using a client/server model • Bridges serve as servers • You first start the bridges, which inform others their IP address/port number (real IP address of the machine on which a bridge is started). • .lan-name.addr • .lan-name.port • You then start stations/routers. Stations/routers look for the IP address/port number information of the corresponding bridge (server), and using socket to connect to it. FSU CIS 5930 Internet Protocols

  17. Suggested running interface • Stations • station –no interface routing_table host_name • Interface, routing_table, and host_name are all files • Routers • station –route interface routing_table host_name • Interface, routing_table, and host_name are all files • Bridges • bridge lan-name num-ports • lan-name is the name of the LAN • Num-ports is the maximum number of ports the bridge has (maximum stations/routers connected to the bridge) FSU CIS 5930 Internet Protocols

  18. Tips for doing well • Realize what is involved • Stay current • Ask questions • Get feedbacks • Use different learning strategies • Knowing what to expect from exams • Persist • Check out http://www.iss.stthomas.edu/studyguides/ FSU CIS 5930 Internet Protocols
