Many paths lead to this state, and it isn't unique to NANOG.

What?
SDN is a poor alternative for those who can't construct a
network with fully automated QoS guarantee.
Even with SDN, QoS guarantee implies QoS routing

If your BGP router supports sflow or netflow and includes ASN in those, you
can use
akvorado, as-stat, or elastiflow.

It’s not a problem, due to cheap, plentiful high-speed memory and rapid prefix
search silicon in backbone routers. The entire Internet routing table consumes
at most a few gigabytes when fully structured (and only a few hundred Mbytes
stored flat). That’s less memory than your average laptop
