Limiters how it works inside ?

[gdo35]

Hello,

I want to understand how limiter works. My first question is :

• Does it work with TCP and UDP, I mean on which layer of the OSI model is it acting ?

• Can one limiter be used for several interfaces ?

• If you have a documentation describing in details how it works I will be be an happy man. ;) I found only "superficial" documentations like pfsense cookbook

• Where can I find a human readable description of what "Diagnostic->Limiter Info" produce ?

Thanks in advance for your help.
