Hi, Yong

A question on your comments.

> (router determines the explicit routes). 

This point has been raised by several folks. It really confuses me. If the
optical switches are equipped with path calculation ability, what's the benefit
to bother router to determine the explicit routes within optical domain
(assuming router can be smart enough to handle all optical network specific
attributes and constrains) than just have routers to determine the end points of
optical trails.

Thanks,

Yangguang
