13 - Load balancing network monitoring traffic with OpenFlow

Diederik Vandevenne (SURFsara)

An OpenFlow switch allows us to build a cheap, scalable and flexible load balancer for our distributed intrusion detection system (IDS). Relying on OpenFlow features alone does not give us the scalability we require. Therefore we use link aggregation load balancing and a feedback loop based on NetFlow or sFlow data to redirect flows to less loaded links.
