1) Use the input and output interface information in the flow.

2) flow-report.

Hi all,

What is a good way of finding the traffic matrix (ingress-
egress traffic for a backbone network) given the netflow data
files?
In doing this there are two problems:
1. The netflow data includes the source and destination IP
addresses but those are not necessarily the addresses of the
backbone nodes. How do we find the ingress-egress pair that
each flow goes through?
2. How do we aggregate the flows to find the overall traffic
between each node pair?

Thanks,
Pedram
