RE: Timer constraint of the HelloInterval and HelloDeadInterval

[Jonathan Lang <jplang@calient.net>]

Young,
  The default values have been modified to read 150ms and 500ms,
respectively. This change will be reflected in the -06 version of LMP.

Thanks,
Jonathan

Subject: Timer constraint of the HelloInterval and HelloDeadInterval


Hi, 
I have a question of the timer constraint of the HelloInterval and
HelloDeadInterval parameters in the LMP dratf, 
draft-ietf-ccamp-lmp-05.txt. 
The draft have proposed as default values of these timer, 5ms and 18ms,
respectively. 
But, the example statement above the one describing the default values
showed 150ms for the HelloInterval. 
I think there is a eding error in default values of 5ms and 18ms. 
Is that right? 
If so, what are the default values of these parameters? 
If not so, could you tell me how to implememt the Hello protocol. 
I think there is no realistic way to implement the software based Hello
protocol. 
As an example, in the layer-1(physical layer) based protection of SONET/SDH
network, 
the detection time for SONET/SDH is specified with 10ms and the restoration
time with 60ms. 
The Hello protocol may be not a layer-1 protocol, but a layer-7(application
layer). 
Thanks, 
Young
