Re: No Upstream Uni-directional LSPs?

[Dimitri.Papadimitriou@alcatel.be]

hi,

from the i-d perspective most of the content deals with
setup, it would also be good if some words concerning
the deletion can be proposed (i mean the reference to 
the method described in current gmpls signalling i-d)
and also to clarify the following paragraph wrt to the 
signalling procedure:
"If a new FA-LSP is required to be set up between the 
LSR and the other edge of the region, the LSR initiates 
the setup of a new reserve-directional FA-LSP. At the 
same time, the LSR may send the Path/Request message 
for the original reverse-directional LSP to the other 
edge of the region."

another point is as follows: we have implementations
ongoing within our community for the set of features that
are described in the common control gmpls signalling i-d's
-> therefore it would be of great interest to gather more
information on deployment/utilisation (ie experimental
i-ds) in the near future in order to be capable to assess 
what might be further considered from that persceptive 
for these i-d's - i think this may also be applied to 
other items that may come out in the same register -

thanks,
- dimitri.
