Rate-Limit (from Radius) burst refill

Im wondering how exactly the burst feature works on the Rate-Limit being set from Radius.

If we set a Rate-Limit of 1M/1M 5M/5M 1M/1M 60/60, then the customer can burst to 5Mb for 60 seconds, at which time the connection drops to 1Mb.

A couple questions:

  1. If the customer downloads at 4Mb, can they download all day at that speed because the burst limit will never be reached?

  2. If the customer bursts to 5Mb+ for 60 seconds and is then limited to 1Mb, at what time can the customer again burst back to 5Mb?

chris-oct, bursts are described in documentation, as well there are some external resoursces, that pretty well describes burst technique in MikroTik RouterOS.
