The problem of path validation of a pure light-path in a Dense Wavelength Division Multiplexing (DWDM) optical network requires the transmission of optical impairments related parameters along the provisioned route. In this draft we propose an RSVP-TE based mechanism to collect and evaluate optical impairments measured over optical nodes along the light-path.
