As traffic engineering and discovering beneficial peering partners is of growing importance for today’s network operations, insights in traffic statistics become an increasingly valuable resource for right decision making. Also, coping with DDoS attacks might require better understanding of the traffic that crosses the infrastructure. The IPFIX Export at IXPs helps to deliver these pieces of information.

This talk presents the implementation of a non-disruptive multi-tenancy software for exporting customer’s IXP flow data. Also, the Internet Protocol Flow Information Export (IPFIX) protocol is being introduced. Open-Source tools for customers to use this service are also presented.
This service is productive at some DE-CIX IXPs and available free-to-use for all its customers. We hope to motivate other IXPs to also provide a similar service.
