[Winpcap-users] Statistical mode help

Not much. Traffic of an average computer... about 15Mbit down and 15 up

How much traffic are we talking about? 

 

Have a nice day

I already did this (capture all packets and sorted them on their ports) but
it was too slow when downloading at full speed. So I turned to statistics as
I only need the bytes up/down per port. 

There are about 100 active ports on average, so 100 instances would be
neccessary...

It depends on the number of instances. For sure I wouldn't open 64k
instances to monitor all the ports. I would capture all the packets (i.e. no
statistics mode) and write my own code to disssect the packets and compute
the statistics.

Thank you for your reply!

 

One more question: are several instances heavy on the cpu?...can I monitor
all the computer's ports without stressing the cpu too much?

you need to use several instances.

Hello

 

I've set the stats filter to monitor several tcp ports. I recieve only the
data for all these ports together and I wish to be able to get the
individual data for each port. Is this possible with 1 instance or do I have
to create one instance of winpcap for every port?

 

Thanx

Michael
