Skype is P2P, literally. The makers of Kazaa made Skype.

If the p2p is acting like Skype traffic there is nothing you can do.
If the two protocols are getting similar, a finer Skype match will
work. If Skype changed their methodology then you'll need to come up
with a layer 7 rule.
Where did you get the rules you have now?

Yeah, on the high latency, high jitter low bandwidth connection we
have here the prioritization and bandwidth limiting of the various
protocols and kinds of traffic makes all the difference between
Skype being unusable to being /almost/ perfect.
On a side now, I had to downgrade from ROS 5.6 to 4.17 because the
log was full of error relating to the L7 processing. There's a
thread over on the MT forum.

The rules inside of this monster?

Do you have to prioritize Skype?

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.
