I have a customer connected to a Gbe interface with an inbound limiter configured as shown below.
They are asking what the policing window duration is. Anyone know?
[quote]traffic-policy {
limiter eth1-vif-200-in {
default {
bandwidth 100mbit
}
}

Hi,
they are asking you about burst-size. Default is 15kB. For your limiter I would reccomend something like 768k (6ms).
burst-size(B) = bandwidth (bps) X burst-period (s) / 8
15k = 1G * 0.00012 / 8
Window duration is: 120 us at line rate.
Good explanation is here - Determining Proper Burst Size for Traffic Policers - Technical Documentation - Support - Juniper Networks
Thanks, great explanation!
