Authors,
Have you given any additional thought on the repesentation of tunable
lasers (and unique resource identification) beyond what is currently in
the draft? The current text is:
If the node has a tunable wavelength transponder, the tuning
wavelength is considered as a part of wavelength switching
operation.
In the past, labels used for TE LSPs always represented a specific
resource that is uniquely identifiable by the node that allocates the
label and resource. Such unique identification is important/required
for certan restart and other corner cases. Your current definition works
fine for fixed lasers that can only be mapped to a single fiber. But,
the defined global label will not uniquely identify a resource on a node
when (a) tunable lasers are used, or (b) when a node supports multiple
fixed lasers that can be (optically) switched to a particular output
interface.
What are your thoughts on how to provide such link-scoped unique
resource identification in the context of your draft?
I don't think it'll be too difficult to address this critical point, and
see a couple of straightforward solutions if you'd like to discuss off-line.
Much thanks,
Lou
