RE: Control Channel Doubt



Hi,
     I think the original purpose of LIH in classical RSVP was somewhat
different. The latest draft of O-UNI (oif2000.125.5) has new
RSVP object RSVP_HOP3. This draft reccomends usage of RSVP_HOP3 object
instead of traditional RSVP_HOP object. This new object has been added
for the intention of non-associated signalling. The struture of
RSVP_HOP3 is  :

              {
                  IPCC's Next/previous Hop
                  LIH (control channel's LIH)
                  TLVs.
              }

The TLVs in the above structure specify the interface for the data
flow. The TLVs can include maxmum of 2 interface Ids (viz. one for
forward direction of data flow and another for reverse direction of
data flow).
But I don't know whether this object will be equally applicable to
GMPLS or not. Whether GMPLS drafts are also going to include the
RSVP_HOP3 object in next revision ?

Authors of OIF draft, Bala, Kireeti etc. : Please clarify whether the
RSVP_HOP3 object has been kept with this intention only or there is
some other reason too.

Regards,
manoj.
