hi i'm tunisian, i have an engineer diploma and a master degree in networks and distributed system. i work on 802.1AE 802.1AF 820.1AH 802.1AD.
i want to find a Phd position in USA or canada concerning the Wan ethernet security.
do you know how i proceed to find a Phd position
thanls all

It would probably be a good idea to do some research around US/Canadian universities and see which of them do your subject.. try looking on google.com

google don't really help me on finding any phd in usa/canada.
may be i'm putting the bad keyword.
i try
phd metro ethernet
postulate phd metro ethernet
postulate thesis METRO ETHERNET
phd LAYER 2 SECURITY
FIND phd LAYER 2 SECURITY
POSTULATE phd mAcseC

ANY RESULT :)

OK well if that is not successful then I suggest emailing universities and asking if they do research in your preferred area.

THEN, what are the known universities working on networks and computer science in general
thanks all.
