  1. ECE 461 Internetworking Instructor: Prof. Jörg Liebeherr University of Toronto

  2. Websites • There are two websites • CCNET:https://ccnet3.utoronto.ca/20079/ece461h1f/ • Announcements • Course: http://www.comm.utoronto.ca/~jorg/teaching/ece461 • Lecture slides, lab information, assignments

  3. Prerequisites • You must have completed ECE 361 before taking this course • I assume throughout the lecture, that you have mastered the material covered in ECE 361

  4. RequiredReading Textbooks: • “Lab Manual”: “Mastering Computer Networks: An Internet Lab Manual”, by J. Liebeherr, M. El Zarki, Addison-Wesley, 2003. • “IBM Textbook”: TCP/IP Tutorial and Technical Overview, by A. Rodriguez, J. Gatrell, K. Karas and R. Peschke, IBM 2006 (available on-line, link from course webpage). • “Online Chapters”: J. Liebeherr (on-line material) Additional: • Reading for each lecture is posted on the website • Additional material may be posted

  5. Comment • I am a co-author of the lab manual • I plan to donate an amount of my estimated royalties from this course to a student organization in the ECE department

  6. Topics Introduction Link level issues Address translation issues (ARP, RARP) Network Protocols: IP, ICMP IP forwarding Router architectures Routing I: Static routing Routing II: Dynamic Routing: RIP, OSPF Routing III: Dynamic Routing: BGP Transport Protocols: UDP and TCP TCP Details LAN switching DHCP and NAT Domain Name System (DNS) Network Management with SNMP Multicast

  7. Evaluation Final Exam     45%   Quiz 1 15%     -   Oct 16, 9:00-10:00am, GB248 Quiz 2 15%     -   Nov 14, 16:00-17:00, GB248 Labs 25% The workload of the labs will be more than 25%. However, restrictions in the Faculty of Engineering limit the credit that can be given to “not closely supervised work”

  8. Labs • The main experience of this course are the labs • Lab is in the Design Center (SFB 520) • There are 3 equipment racks with identical equipment • Equipment is brand-new

  9. Lab Sequence

  10. Structure of the Labs • Each lab has three phases: • Prelab (individual) • Exercises that prepare for the lab session • Prelabs are turned in before the lab session • Prelabs are graded (10%) • Lab session (with lab partner) • Configuration and measurement experiments on the equipment • Perform exercises described in Lab Manual, collect data • All lab exercises can be completed without supervision. • approx. 3 hours • Post lab report (with lab partner) • Summarize and analyze the data from the lab session in a typed report • Lab reports are graded (60% completeness/correctness, 30% quality of presentation) • Late policies for pre-labs and lab reports: 20% of total grade per day

  11. Structure of the Labs • Each lab has three phases: • Prelab • Lab session • Lab report. • Pre-laboratory Assignment (Prelab). Exercises to be completed in advance of the associated lab session. The prelabs ask you to acquire background knowledge that is needed during the lab exercises. Each prelab has a question sheet that must be completed before the corresponding lab session. The answers to the prelab questions are graded.

  12. Structure of the Labs • Lab Session. Lab exercises that are performed on the equipment of the Internet lab. All lab exercises can be completed without supervision. The time to complete a lab session should be three hours on the average, but may vary. Complete the laboratory activities to the extent that you can. The activities during the lab session are not graded, however, data collected during the lab session are needed to complete a lab report. • Floppy disk symbol in the lab manual indicates when you have to collect data. • NOTE: YOU NEED A USB DRIVE TO SAVE DATA ! Floppy disk symbol

  13. Structure of the Labs • Lab Reports. After each lab session, you prepare a lab report that summarizes and analyzes the findings from the lab session. A notepad symbol indicates an assignment for the lab report. The lab reports should be submitted as a typewritten document. • The lab report is generally due 1 week after the lab session. The lab report is graded. • Each lab has an anonymous feedback sheet. The feedback sheet must be submitted with the lab report. (It is used to improve the setup and organization of the labs) • Note: Saved data should be included in the report only if it is requested in the lab report, and if it is used to answer a question. Filtering the relevant measurements for the answers of the lab report is part of the analysis. Notepad symbol

  14. Lab equipment • The equipment of the Internet Lab is not connected to the Internet. • You will work on administrative (root) accounts. Please exercise caution when modifying the configuration of the Internet Lab equipment. • NEW: • The Linux PCs are booted from a CD (LiveCD). Each time the PCs are re-booted they are set to the same initial state. All changes on the PC are lost when rebooting the system.

  15. Rules for using the lab • Find a lab partner. • Sign up for a time slot in class. Your time slot is allocated for the entire semester. • You are guaranteed access to the lab during your time slot. • If a time slot is not used 15 minutes after the start time, it becomes available on a First-Come-First-Served basis • Outside your assigned lab section, you  may use the lab anytime you want, as long as the equipment is available • Submit lab report and prelab solutions in class: • Due dates are posted on the web page • Prelabs are due before the lab session starts

  16. Structure of the Labs • Before you go to the Internet Lab • Read lab manual and do related reading (a few hours) • Complete prelab (<1 hour, if you have done the reading) • Turn in prelab (save a copy for the lab session) • In the Internet lab: • Show up for your time slot • Bring a USB flash drive, the lab manual, and solutions to prelab • Complete exercises (1 hour to several hours) • Take measurements • Save data to USB flash drive • After the lab: • Use data on save data to floppy • Write lab report • Submit lab report by due date (including feedback page)

  17. Sign-Up (3 groups per time slot, 2 students per group) No access to lab on Saturday and Sunday
