Running out of RSVP-TE bits?

Hi,

After a couple of conversations today I wonder if we should worry
about the way we allocate bits from the flags fields in the
Session Attribute object and the RRO subobject.

These flags are very rare and we need to assign them with the
greatest care. Is there currently any policy for managing this
resource to ensure that there will still be bits available when
they are needed? Or can we simply use them on a first-come,
first-served basis?

Note that draft-ietf-mpls-nodeid-subobject-01.txt takes the use of
the RRO subobject flag up to all but two bits used.
draft-iwata-mpls-crankback-06.txt uses all of the remaining
Session Attribute bits.

Thanks,
Adrian
