ASON and OBS Performance

Dear All,

This is my first email to this forum and I would like to have your 
guidance, supervision and help.
If you could kindly point out and highlight some of the current master's 
(Research direction)  for performance analysis of Automatically switched 
optical network(ASON).I have a simple applied queueing theory background 
and would like to work on the basics to research level on ASON in 
combinition with OBS.
Looking forward for your cooperation.

Thanks & Regards,
Murtaza Bilgrami.
