Hello David
You’re correct that Bc (Burst Commit) is the maximum capacity of the bucket, but the calculation is not as straightforward as you’re thinking.
The formula for Bc is Bc = CIR * Tc.
Tc, the time interval, is a value that is calculated by dividing Bc by CIR. In some cases, like in the Cisco default configuration, Tc is defined as 1/32nd of a second, which is where the division by 32 comes from in the OCG.
So if we’re using a Tc of 1/32nd of a second and we want to calculate BC, we’d multiply the CIR by 1/32nd of a second. This gives us the number of bits that can be sent during that time interval.
So, in your case, the Bc value would indeed be 16,000 bytes (or 128,000 bits) if we were simply converting bits to bytes. But because we’re calculating the number of bits that can be sent in a specific time interval (1/32nd of a second), we use the formula Bc = CIR * Tc.
I hope this has been helpful!
