I have two 2610 routers connected back to back using serial
interfaces, and router 1 connected to ISP using another seial
interface. Router 2 I use for connecting the client networks. Using
the back to back cable traffic shaping is done.

My downlink is 2Mbps and uplink 512Kbps. But most of the time my
uplink exceeds the limit and ISP starts complaining. And the worest is
some of my users are using Net2phone and they cant hear the remote
party most of the time. I suspect this uplink overloading as the
reason for that too.

The biggest problem is i cant figure out how this happens, cos i have
no way of monitoring activity of these ports by protocolwise.I have
MRTG but it's not a solution for my problem.

And most of all I cant identify the exact point (interface) where all
these uploads genetrate because the equation of the counter values
does not give a proper idea (input counter values in bits/sec <>
output couner values). and the upload requests from users are far less
from the amount recorded at the back to back interface of the router
2.

Is it a RAM problem in the routers or something else? Please help me
in this issue because the users are always complaining of slow speeds.
And most of all I want to find out fro where these uploads generate...

Thanks in advance..

High upload utilization can impact downloads as ACK packet can't go back
to the sender. Peharps is this youtr problem. Configuring high priority
on ACK packets can help...
