Hello all,
So a customer of mine has been asking me about burst-size-limit on Juniper routers. Before I begin, I have a Juniper M5 running 7.6R4.3. My customer has the burst size limit set on his port, but he is asking me some questions I can't find the answers to. This was a page from Juniper's site explaining burst-size-limit's... http://www.juniper.net/techpubs/software/junos/junos76/swconfig76-network-interfaces/html/interfaces-summary53.html My customer is asking about the conditions for the RESET of the burst counter... " its simple enough that if you go from 1 to 10mbps on a 1mbps limited connection, and are allowed 1 Gig of traffic, it starts counting at 10mbps, and when it hits 1 gig, it shapes to 1Mbps. That's easy. But what if you burst to 10Mbps for 200 megs, then drop to 1Mbps for 10 seconds, then burst to 10Mbps for another 300 megs, drop to 1mbps, burst again, etc - you could end up with an aggregate equivalent bandwidth rate of 9Mbps for eg even tho your shaping is at 1mbps. I'd expect there's some counter or multiplier or something that determines how long you have to *NOT* burst for before the counter is cleared (or some decay rate or something, perhaps every non burst byte sent comes off the burst counter, that'd be one way. I would think Juniper would be smart enough to have some sort of built in reset but I am no certain. Does anyone know offhand? Any and all explanations would be greatly appreciated, Thank you very much everyone.
