Subject: Doubts regarding LSP encoding type

Hi All,
        The draft "draft-ietf-mpls-generalized-signalling-02.txt" defines different values for LSP encoding type. How does the implementatin of a control plane differ if it receives the LSP encoding type  packet/SDH/Digital Wrapper/Lamda/Fiber etc.

My understanding is that if the LSP encoding type is either packet/ethernet, then label is just a 32 bit integer (as we already have in traditional MPLS). But if LSP encoding type is SDH, SONET then the label has to be in the form of {S, U, K, L, M} format. If the LSP encoding type is Lamda then the label represents the lamda (specific frequency). If LSP encoding type is fiber, then label is the fiberId itself. Can u please describe a scenario in which the LSP encoding type will be used as a "digital wrapper" ?

Please clarify.

Regards,
manoj.
