Hi Snigdho, I think we should meet and discuss in Dublin, face to face
discussions are sometimes easier than e-mail, but see below for one
last comment.

---> Hmm, I
thought this was clear from the above: "When we encounter OEO devices
such as wavelength converters or regenerators many of these can
accomodate multiple signal types but need this basic low level
information to determine compatibility." By including such information
as modulation type, modulation parameters, and bit rate in signaling we
can configure the devices along the path. For example a 3R regenerator
or OEO based wavelength converter is needs timing (bit rate)
information (see ITU-T G.872 Annex A).
[Bardalai, Snigdho] Sorry, my question was not clear. What is
preventing us from using the "signal type" for this purpose?
--> The same "signal type" such as an OTUk, STM, or an Ethernet
might use different (a) modulation type, (b) modulation parameters, or
(c) FEC (which can also affect the bit rate). Or do you mean a
generalization of the "signal type" to include these new fields for a
"light path" (or whatever we choose or are allowed to call it). And
this information is, in effect, lower layer information and hence
appropriate to the WSON discussions.
