shots).
Clarification of problems
26/28 on HW#4:
o For problem 26, assume that Initial Deviation = 1.
o For problem 28,
continue the example from problem 26 at iteration 19.
Please note

Reading Assignment for
week of February 27: Chapter 4
HW#3 is due on Monday, March

Please note: Independent
work is assumed on all submitted HWs. Failure to do so violates UTD Code of Conduct.
Please be reminded that we
cannot accept homeworks by email.
Clarification to problem 4
on HW#2: A transmission at time t will be successful
if the previous transmission AND the one after time t will be at least one
“slot” away. For each lambda (say, lambda =1.0, 1,1,
1,2, … 3.), your program should simulate many (say 1000) such “events” of
transmitting a packet and seeing whether it was successful or not. To see
whether a packet transmission event is successful, you “select” two numbers and
see whether BOTH numbers are greater than 1 (the first number represents the
time when the packet previous to time t was
transmitted and the second number represents the time when the next packet
after t was transmitted). To select the two number,
use the formula x=lambda*log u and the rand()
function. The rand() function gives a random number u
between 0 and 1. Plug this number u into the formula x=lambda*log u and this
gives you x, which is the time before/after the current packet was transmitted
(in units of slots). (A note – the log function is natural log (i.e., log base
e).)
HW#1 has been graded.

This is an
intermediate course in computer networks. In this
course, we will cover both the classical/fundamental topics in computer
networks and a number of current/recent research topics related to modern
computer networks. Most, but not all, of the advanced topics will be relevant
to Internetrelated research and they will be mostly on the Layer 3 and above.
Most of the classical topics will be covered following the Peterson and Davie
book. Additional research topics will be covered through research papers, links
to which will be provided to students in due time. In particular, toward the
end of the semester, we will cover a number of recent and current networking
research areas through relevant research papers. The main goal in this part
will be to expose students to some ongoing active and challenging research
areas in networking.

If you did not turn in up to 2 homework sets due to a
legitimate reason, the turnedin assignments will carry the total of the 25% of
the final score.
Final project requires an inclass demo. More details
to follow.
Any
final score component missed not due to a legitimate reason will count as no
credits in the final score calculation.
See
