Diego,

Please see draft-ietf-ipo-impairments-00.txt for optical constraints. 

Thanks,
Ayan

Peter ,all,

           a  comment  about  draft-ietf-mpls-generalized-signaling-04.  In
the
draft  there is the label set object that is very useful in All optical
networks
with  CI-incapable  nodes  but  lambda  conversion  is  only one of the
problems
related  to  path  establishment  in  such networks.  I mean what about OSNR
and
non-linear  impairments? What about gain variation and power equalization?
Where
are covered these topic?

If  I  can  find  a  path  feasible from the lambda continuity point of view
who
assure me that I have the needed Q at the end of the all optical path?

Best regards.
