Hello Manoj,

information ( STS->VTG->VT) in some proprietary format which is
understandable by neighbouring nodes .

(There is no proprietary format to use, the label format supports all
cases.)

It depends on your logical topology. You could have a VTG (virtual) link and
in that case the label would be relative to that link (highest part non
significant). At the other extreme you could specify the full label. This
has nothing to do with the monitoring or with the allocation of higher-order
signals. Up to you to decide what you want to do. Since a label is always
interpreted in a particular context, this context will allow you to know how
it must be encoded.

Kind regards,

Eric

Hi ,
      I want to estanlish a DS1 trail , using GMPLS signaling .

      The DS1 will  get mapped to a single VT in a VTG , and will get
transferred to other end 
      using VT Switching .

      All the nodes particpating in the connection will do VT switching .

      Can I specify a VT by a single label , or  I need to encode this
information ( STS->VTG->VT) in some
      proprietary format which is understandable by neighbouring nodes .

      I would be interested in knowing how people do this .

Regards ,
Manoj
