Doubt in draft draft-ietf-mpls-generalized-signalling-05.txt

["manoj juneja" <manojkumarjuneja@hotmail.com>]

Hi All,
         I have following doubt in "draft-ietf-mpls-generalized
-signalling-05.txt" draft.
This draft has introduced new field switching type in Generalized Label
Request Object. After looking at the structure of switching type field
in latest OSPF document (GMPLS extensions to OSPF, Field Name :
Interface switching capability descriptor), I could not make out why
this is present in per LSP establishment request ? This field
advertises the bandwidth (both min. and max.) for various priority
levels (p = 0 -> 7). Furthermore, this field also contain Encoding (I
assume LSP encoding type) field which is already there in Generalized
Label Reqest object.
I am not able to understand why this type of information is required in
Per Connection Establishment Request ?

Regards,
manoj.
