The CCAMP Working Group would like to inform you that we have initiated control
plane work on supporting Flexible Grid DWDM networks with the following

Our understanding of the n and m parameters, when used to describe a frequency
slot, have to be integer, as per G.694.1.  From a signaling perspective, since
we are signaling actual frequency slots on a hop per hop basis, we would use
integer values. It is our understanding that typically a consistent value of n
would be used for a path over multiple network elements, though the
Recommendation does not constrain it.

The CCAMP WG would like to ask if our understanding is accurate.

We would appreciate if you would continue to keep us informed of your progress
and development on capabilities for the data plane that may affect the control

Best regards,
Lou Berger and Deborah Brungard
