So, something that might be useful would be if the requirements I-D made
some statement about the number of VCAT groups likely to be originated by a
It is my *guess* that the number of such groups is likely to be smaller
than the number of LSPs associated by the same sender. Thus, the size of
the group ID does not need to be larger than the size of the LSP-ID.
If there is a need to overload the semanitc of the group ID for correlation
with LCAS or something, then we should discuss the point, but so far we
have only discussed it in the context of grouping together a set of LSPs.
