Message 4/3/2011:

**Grades were given to mazkirut. Will be pulished early next week. I just sent email to all of you with grade explanations and pitron Bet Sefer.**

Message 13/2/2011:

some corrections to lecture notes:

Lecture notes 4 - Page 4: last equation -- is not right. Pleas take from Kleinrock.

Lecture notes 4 Page 6 : e^(-lambda t_0 ) should be e^(-lambda delta t)

Lecture notes 3 page 4 middle: Sigma Pi_i should be equal to 1 (and not to zero)

General Comments and comments about the exam 8/2/2011:

1. Re the class notes -- Notes # 6 -- note that Jackson networks hold when all service times are exponential. If it is missing in the notes -- please add it. (and you can read the one page describing them in Kleinrock Chapter 4).
Lecture notes 1 and 6 have been updated for small corrections.

2. Material for the exam: Everything we covered in the theoretical lectures is for the exam. Regarding potential questions -- you can look both Kleinrock's book (chapters 2 -- parts of it, chapter 3 [all of it], chapter 4 [only the relevant things. There are not too many questions on the things we covered, so I can ask only things that require understanding and usage of what I covered in class], and the appendix on generating function as SUPPORTING for analysis of Markov Chains). Also -- Bertsekas and Gallager Data Networks (chap 3 in 2nd edition) -- has plenty of questions on the things we covered in class.

3. The exam will consist of ABOUT 3 questions (probably with several sections each). In a questions of multiple sections -- if the calculation in one section (say x) depends on the calculation in a prior section (y), and if you unfortunately cannot find (y) -- we might have the option of granting you (y) (of course without giving you the grade for it... :-( ) .

Emphasis will be given on modeling problems using the models we studied (Markov Chains) and deriving their performance.

### Our meeting for final discussion of P2P subjects will be held right after the exam at Shreiber 9.

As said in class -- this discussion will be accounted for in the final grade.Please send me in advance a (short) description of issues you plan to discuss.
