As usual the midterm takes place at 12:30 and we have two rooms at our disposal: inm202 and inm203
so please use both of them.

reminder: any electronic equipment (except a calculator) is NOT allowed. so print the slides before coming.

Please note that the research exercise report has to be written in English.

End of page 6 (cc.pdf):

"Then we have obviously λi = λ and λ'' i = λ'' for some values of λ' and λ' which we compute now."

Please indicate the correction.

Hi,

I think there might be a typo in the tutorial on cc.

On page 21, section 1.6.1

Shouldn't the equation 1.21 be without the 1-nixi? but as the one above and the next one (1.23)

mui * (nixi + ri) ?

Thanks,

Christophe Gudin.

Hi,

In the exercise 3, when we set up the preferences of the routers, all the routing tables converged. The paths chosen weren't the optimal ones that the routers would like, but they looked correct. For example, R1 had a direct path to R4 and not one going through R2 and R4.
Everything looked correct to us, so we don't know what's the problem that we need to fix. Any help?

Thanks a lot.

Have a nice vacation

Hello

There's something we don't get. If we try some filtering with a simple acess-list and IP prefixes everything works as expected. Now if we simply replace the lines access-list with ip as-path access list, it simply denies everything, even if we have a permit any..... HELP!

Please be aware that additionally to the slides on congestion control, there also is a tutorial online (cc.pdf).
