Basically if some other process is running there is a chance you can't get to the rsp hello message processing fast enough so you would declare the link down when really it's not. > > The pseudo-preemption you mentioned, could you give more details? Not really. Just a way for the scheduler to signal that a process needs to run now versus just being scheduled like another process. > > 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? No. You can use them you just can't tune them too low or you run the risk of getting false positives. > (considering BFD for FRR is not ready to use) > > Tks, > Alaerte > > -----Original Message----- > From: ext Rodney Dunn [mailto:[EMAIL PROTECTED] > Sent: Thursday, March 29, 2007 4:26 PM > To: Vidali Alaerte (Nokia-NET/RioDeJaneiro) > Cc: [email protected] > Subject: Re: [c-nsp] RSVP Hellos > > None other than the standard issues of subsecond hellos and process > scheduling.
