QOS Formulas Flashcards
1
Q
Formula to calculate Tc
A
(Bc [bits] / CIR [bps]) × 1000
2
Q
Formula to calculate Bc
A
CIR × (Tc / 1000).
3
Q
What is the formula to find the number of Tc’s in 1 second?
A
1000 ms / Tc[ms]
4
Q
Formula to determine how many packets conform within each Tc?
A
Bc / packet size in bits (rounded down)
5
Q
What is the formula to find out how many packets would be sent in 1 second?
A
Number of packets that conform within each Tc × Tc’s per second
6
Q
Formula to determine the CIR
A
Packets per second × Packet size in bits
7
Q
Formula to calculate the time interval it would take for 1000 packets to be sent at interface line rate?
A
(Bc [bits] / Interface speed [bps]) × 1000
