Ok,
I`m completely lost on a few things.
Shaping. When you shape using a Be, that Be bucket can be used in to make up
bandwidth loss from the Bc bucket not filling up on a given interval. That I
understand. But, can you burst above CIR, or does it just mean, you burst
above CIR per Tc to make up an average rate. I mean, that you can never
really burst over CIR, right? You can only burst over Bc per interval to
make up the average CIR. Am I correct?
I`ve seem examples where you might have a port speed of 64k, and a CIR of
56, can you burst above CIR? If Be = (AIR-CIR)xTc, this looks like you can
burst over CIR, right? I suppose this possibility of bursting over Bc is
negotiated with the service provider then? For example, they might sell you
a 56k CIR, with a port speed of 64k, and allow you to burst up to 60k. Can
it work like that? I have policing burst questions as well, but wanna knock
out this concept first. Anybody got any great references from the DocCD, or
otherwise that really breaks this stuff down to a dumbass level?
I`m lost,
Erich
