Label Set and Suggested Label
The GMPLS drafts specify the use of suggested label and label
set in a very generic way. These are not mentioned based on specific
The following question comes to mind while reading the draft.
Whether the suggested label and label set are going to be used in SDH/SONET
The OIF's O-UNI v 1.0 is applicable for establishing SDH/SONET LSPs. They
don't use the suggested label at all. Regarding the usage of label set, it
mentions that if a node wants the upstream and downstream labels to be same
in both the directions then the upstream label should be included in the
label set. Is GMPLS looking for the this type of usage for label set in
SDH/SONET LSPs ?
Can I have a action field indicating range (include/exclude) in label set
for SDH/SONET LSPs ?
What is the reason for including the SDH/SONET list of labels
(include/exclude) for SDH/SONET LSPs ?
I can understand the usage of suggested label/label set on LSC interfaces.
Please don't give answers like GMPLS is a generic framework and O-UNI is a
sub-set of GMPLS or label set/suggested label is a carrier requirement.
