[c-nsp] RSVP Hellos

[Alaerte.Vidali at nokia.com]

Hi Rodney,

Do you have details of problems related to process scheduling in 76xx
when using aggressive RSVP hellos?

The pseudo-preemption you mentioned, could you give more details?

I agree that monitoring loss of signal is the preferred way to do it;
but for cases where there is no LOS capability, do we have other option
besides RSVP hellos?
(considering BFD for FRR is not ready to use) 

Tks,
Alaerte

None other than the standard issues of subsecond hellos and process
scheduling. We implemented a pseudo-preemption type mechanism for BFD to
get fast reaction.

RSVP fast hellos isn't the preferred way to do it.

LOS is.

There was/is some talk around BFD triggered FRR.

No idea what that roadmap is though.
