Hey guys,
Reading over some old JNCIA material and trying to get my head around policers.
Everything makes sense except for how often and how quickly the token bucket refills itself.
My theory is that the bandwidth-limit parameter, as well as defining the allowed rate limit before the policer is activated, also defines how often and how fast the token bucket refills. For example, if you define 10m as the bandwidth-limit, the bucket will refill at 10Mb/s up to whatever you define the burst-size-limit as.
This is somewhat backed up by this post here: http://forums.juniper.net/t5/Routing/Asking-about-the-burst-size-limit-parameter/m-p/223681/highlight/true#M10592
I just wanted to be sure my understanding of this topic is accurate. It's kinda difficult to comprehend as we're talking in milliseconds and examples of burst-size are always ~5ms of the interface wire speed - which in human terms is useless, because that's less than .5 of a second, but I'm thinking in terms of file transfers and I'm sure the construction of policers is very situation-specific.
Anyway, I digress, the question is as above.
Thanks in advance,
Kindest Regards,
Andrey
