Gurus,
This is what i understand and need clarification on.
AR= 512Kbps ; CIR = 64Kbps.
Bc= CIR x Tc / 1000
Be= (AR-CIR) x Tc / 1000
#1. So im able to the above calculation if the question mentions " allow DLCi 103 to burst upto port speed " then the Be formula works with (512-64)kbps x TC/1000, my doubt comes when the question says, " Allow the DLCI to burst upto 128 /384 Kbps for 32ms or 64ms etc etc." here how to look for the Be, as the burst is not upto port speed, so im struggling to find a "Universal rule".
#2.Secondly; in questions where its not mentioned any Tc value I would like to
go for 125ms as default, what other "Signs" i should look for where the Tc value can be influenced, e.g. In one IEWB it mentions " The packet above 960 bytes should be fragmented". Is this a catch!! as the the Tc chosen made .
hope i was clear enough... :-)
Shukla.
