Hello
many L2 (and likely L3+) switches have such a feature as rate limiting. It seems such feature is applied per port basis, as well as per connection (session), if we consider L3-L4 switches. But now I'm more interested in layer2 and in this connection I have two questions to ask:
(1) Is a "rate limiting" an attribute of QoS mechanism? (2) what methods/algorithms are used to limit rates of packets per port? I've read aboit random-early-drop, and weighted random-early-drop; as I know there is also a set of other algorithms. But I believe those are mainly to solve congestion problem? Or rate limit is also one of ways to fight with congestion?
I would appreciate if anyone could point me at right direction :) Thanks.
