Hi Kings, This is to change from bits to bytes since bc in in bytes.
cir = Bits bc = bytes >You can see that we divide CIR by 8 and then multiply with Tc. >When Bc = CIR * Tc, I am wondering why are we dividing CIR*Tc by 8? Thanks. Wilson F.

Bc and CIR calculation for Policing (Kingsley Charles) ---------------------------------------------------------------------- Message: 1 Date: Thu, 9 Jun 2011 21:11:34 +0530 From: Kingsley Charles <[email protected]> To: [email protected] Subject: [OSL | CCIE_Security] Bc and CIR calculation for Policing Message-ID: <[email protected]> Content-Type: text/plain; charset="iso-8859-1" Hi all To calculate CIR, we use the following formula: CIR = Bc/Tc Thus Bc = CIR * Tc But the actual formula, we use to calculate Bc for Policing and Rate-limiting is as following: Policing ====== Tc = 0.25 secs BC = CIR/8 * 0.25 = CIR/32 Rate-limiting ========= Tc = 1.5 secs BC = CIR/8 * 1.5 BE = 2 BC You can see that we divide CIR by 8 and then multiply with Tc. When Bc = CIR * Tc, I am wondering why are we dividing CIR*Tc by 8? With regards Kings -------------- next part -------------- An HTML attachment was scrubbed...
