This document discusses how Freie Netze München used IPFIX and ElastiFlow to monitor their network traffic and make better peering decisions. They exported encrypted IPFIX data from DE-CIX routers via UDP to ElastiFlow, which provided analytics on traffic flows. This identified their top sources and destinations by ASN, mainly eyeball networks, cloud providers, and content providers. Freie Netze München was then able to set up direct peering sessions with most of these ASNs to improve routing resilience and learn more about their network traffic patterns.
