Thanks for your answer and sorry for my poor english.
When I talk about “network traffic analyzer”, I mean the way Packeteer does.
A kind of learning mode.
From my point of view ( I am not a specialist), at the begining of a QOS stuff I don’t know how the bandwidth is used and what ports and/or l7 protocols are used.
So before to decide anything, I have to learn who is using what.
Then I’m able to decide how I’ll share the bandwidth and what and who I’ll lock.
May be I am wrong… Sure I am unexperimented in ZeroShell 😉
