Re: IPv6 traffic percentages?

We know the GPS coordinates for each BGP next-hop in the network, and
traffic is sampled on ingress at the edge of the network and reported
to pmacct (*flow), which also receives a RR-style BGP feed for
correlation.

We can know where (geographically) a packet enters the network, where
it leaves the network and to what address family it belongs.

i have only seen pmacct used for aggregated flow/traffic.  you actually
know where each packet enters and leaves?
