Guys,
I've gotten so much out of these forums. I appreciate you letting me be
a part of them. I had an idea which I don't know if it would be of interest to
anyone here but I hope it is. It has to do with bandwidth management and P2P
and Skype and their interaction in MT's RouterOS.
I've noticed some P2P traffic gets picked up by the L7 regex for Skype.
Since anyone doing bandwidth management for both Skype and P2P is probably
trying to prioritize Skype and de-prioritize P2P and MT's confusing the two is
going to have negative consequences. Having the P2P traffic get into Skype's
queue does the exact opposite of what I'm trying to do.
You'll see when MT's L7 Skype regex is misidentifying P2P traffic as
Skype traffic is the inbound and outbound traffic will be greatly unbalanced,
much more so than even if one side was doing voice and video and the other side
was just doing voice. I was seeing hundreds of Kbps down and one or two Kbps up
on the Skype queues. I knew that wasn't right. I looked and sure enough there
was bit torrent activity going on. I wonder if some of these bit torrent
clients don't try to make their traffic appear to be traffic of legit apps.
I'm using a modified version of Butch's script. What I'm doing with
regard to Skype and P2P to correct this problem is the part of the script that
detects P2P traffic keeps a list of the local users's IPs. I have the part of
the script that prioritizes Skype ignore the user's traffic if they're one of
the P2P'ers. That means not only does their P2P work poorly but their Skyping
is not going to be as good as it would if they weren't messing around with P2P.
I'm very heavily trying to discourage P2P here.
