Packet's Per Sec

Hello, Is it possible to retrieve the packets per sec a device on a network
is seeing for any number of connections?

I have a device that can handle 64 TCP connections and in side any given TCP
connection is can have up to 128 industrial communication connections (known
as CIP, this is a Rockwell Automation device is anyone cares). The big
picture of this, is not so much the connections but the maximum packets per
sec the device can have at once (which is 5000 pps max).

Another ticky bit of info is this device has either implicit or explicit
forms of connections and its the explicit messages I care about. I need to
see if we are at times exceeding the allowed pps on this device with too many
messages..

Thank info would be great...

regards,

robert

Yes I believe this is possible, but a little tricky. You might look at using
WMI to get this information, or perhaps WinPcap.

I did something like this for monitoring multicast bandwidth (using just VB.Net
code, not WMI or WinPcap) but that's a little different.
