Only one comment: the TE tunnel hand-off in Tutorial draft, is defined for the "point",
I mean :
TE tunnel hand-off point - an access link or inter-domain link by which a multi-domain TE tunnel enters or exits a given network domain, in conjunction with a layer network resource (such as a wavelength channel or ODUk container) allocated on the access/inter-domain link for the TE tunnel
