Hi, LMP people
I have a question of how to dynamically configure label values between LMP peers using LMP.
According to the section 3.2.1.1(Port and Wavelength Labels) of rfc3471(GMPLS Signaling Functional Description),
the document says that label values may be configured or dynamically determined using a protocol such as LMP.
Here, I would like to apply the same concept into the case of SONET/SDH labels as well.
This is because that the scope of label at least includes time-slots, wavelengths, or space division multiplexed positions, as described in the document.
However,
I am not sure that there is an exact description for dynamic configuration of label values in case of SONET/SDH labels in the LMP specification.
I think that the contents for dynamic configuration of the values is located in the section 4, Link Property
Correlation of the LMP specification, draft-ietf-ccamp-lmp-08.txt.
I think that in case of the port and wavelength labels
the correlation procedure and its formats could be applied as described in the LMP specification.
However, in case of SONET/SDH labels, I have still no self-confidence in understanding the description.
In SONET/SDH, labels may be time-slots between LMP peers, which have the format of S/U/K/L/M
as described in the section 3 of draft-ietf-ccamp-gmpls-sonet-sdh-08.txt(GMPLS Extentions SONET and SDH Control).
I think that if the current description of the LMP specification is applied to the SONET/SDH case,
the dynamic configuration of ports is possible,
but the dynamic configuration of time-slots within a port is not possible and is not required.
This is my understanding.
Could anyone of LMP people tell me the exact understanding for the dynamic configuration of time-slots?
