CCAMP,

One of the items which we identified during our WSON meeting discussion was=
 to ask Q6's input regarding parameters for use to do impairment-aware path=
 computation. Here's a proposal, the parameters listed are from one of the =
drafts. If any additional suggestions, let us know.

Let us know if any concerns/comments.

Deborah and Lou

The CCAMP Working Group of IETF would like to thank the experts of Q.6 that=
 were able to participate in our recent March meeting in Orlando. We believ=
e the discussion was very helpful in progressing our work on WSON (Waveleng=
th Switched Optical Networks) and Flexible Grids.

During the discussion regarding improving the ability to do impairment-awar=
e path computation for path activation, it was noted that ITU-T G.697 defin=
es optical monitoring parameters for performing various activities. While s=
ome of the ITU-T G.697 parameters may be useful for path computation, not a=
ll parameters may be needed, and other non-G.697 parameters may be useful. =
We would like to ask for your expert review of a potential list of paramete=
rs which may be of use in computation to improve the choice of an optical p=
ath to activate when multiple choices are present. We understand this list =
would not be exhaustive and it would be system dependent. The aim for this =
work is to provide a basis for defining protocol encoding aspects for the p=
arameters. It is outside of the scope of CCAMP's work to define the computa=
tional models used by a system vendor or operator.

Currently, we have noted the following parameters:
*       OSNR
o       Power Input (required by OSNR)
*       Chromatic Dispersion
*       Differential Group Delay

We would appreciate any input which you can provide regarding this list.

We would appreciate if you would keep us informed of your progress on ITU-T=
 G.680 and Flexible Grids.

Best regards,
Lou Berger and Deborah Brungard
