Analysis of IP flow records from Internet peering points provides some interesting challenges. The total volume is large to say the least, the number of hosts very large and diverse and the number of flows per Gbps of bandwidth is larger than most enterprises. The traffic is all asymmetrical and the infrastructure seems to be always evolving. The challenges are all surmountable and the analysis is effective and useful. The infrastructure seems to be always evolving so that just when the evolution from SONET cores to everything Ethernet is completed the introduction of orchestrated NFVs begin. The new infrastructures again provide some challenges but they also provide some opportunities for new approaches using orchestrated Security Functions Virtualization (SFVs or SNFVs). The orchestration capabilities can enable scheduled surveillance of traffic and network elements.
