Hi authors,
You say:
In practice, however, the RSVP
Resv message for the new LSP can reach the ingress before one (or
more) LSR(s) have completed programming their forwarding for the new
LSP.
I suppose we are falling into the variation cases of 3209's "SHOULD".
The node SHOULD be prepared to
forward packets carrying the assigned label prior to sending the
Resv message.
Indeed, pipelining seems to be quite as common in packet networks as it is in
optical networks.
You might find RFC 6383 useful reading.
