Description: |
The material covered in this course compliments the material being covered in COMS 4119: Computer Networks. Both courses can be taken for credit. Both courses will cover topics that relate to the current Internet, but the manner in which these topics will be addressed is significantly different, in that COMS 4119 will focus more on software and protocol issues (programming, header formats, etc.) and ELEN 4710 will focus more on theoretical and modeling issues (protocol analysis, graph and stochastic program models). 4710 will contain more math, while 4119 will contain more programming. Topics: Covers theoretical fundamentals of network engineering. Topics include theoretical underpinnings of the physical layer; design, protocols and analysis of the data-link layer and medium access sublayer; design, routing algorithms and prefix addressing for the network layer, and evaluation of congestion control and connection setup/teardown algorithms for the transport layer. |

Homework(s): | Non-CVN students: Unless otherwise
specified, homework will be due one week after it is assigned and
should be turned in by the beginning of class. At that time, a
physical copy of the assignment must be received. If you will not
attend class on that day, you should slide the homework under my
office door (CEPSR 816) or in my mailbox (Mudd 1312) by 9am on the day
it is due. Before class but after 9am, I will collect the homeworks
from my office and mailbox. E-mailed/faxed homework and late
assignments
will not be accepted unless approved in advance. Approval will
only be given under extreme circumstances. You are expected to
produce your work in a timely manner. CVN students have an extra 48
hours to turn in homework.
You may discuss and work on questions with other students in the class. However, you should write your solutions on your own. In other words, if I were to later ask you to re-derive one of your homework solutions or to solve a similar problem when you were without your friends, you should be able to do so or have a clear understanding of how to approach the problem. This can only be learned by doing, so you should do your homework. |
Midterm exam: | 10/15 during classtime, closed book, no calculators |
Final exam: | Date/time TBD |
Class / office-hour participation: | If you ace your tests and homeworks, you will get an A+, even if you do not participate in class or come to office hours. However, if you don't ace your tests and homeworks, but you can demonstrate to me that you have learned the material in another fashion (mainly via office-hour discussion in which you work through additional problems), you can improve by up to one letter grade (e.g., C to a B). To reiterate, it is possible to improve your grade by demonstrating an understanding of the material. |
Grading: | Assignments 20%, midterm 35%, final 45%. On-campus students can also improve their standing by class / office hour participation |
A note on exams: | I am more interested in your gaining an understanding of and developing an intuition for why certain rules, laws, and techniques hold and are used. I am less interested in your ability to memorize these rules, laws and techniques and blindly apply them without intuition as to why they work. Thus, I will try to design the midterm and final questions to test your understanding of the concepts, not your memorization skills. I realize that some memorization will undoubtebly be required, but hopefully the memorized concepts will be those that can be rederived via your intuition. |
Computer hardware and software requirements: | None |
Homework submission: | Due 1 week after assignment before class. |
