Evolution of cache replacement policies to track heavy-hitter flows

Flow-based network traffic processing, that is, processing packets based on some state information associated to the flows to which the packets belong, is a key enabler for a variety of network services and applications. This form of stateful traffic processing is used in modern switches [1] and routers that contain flow tables to implement forwarding, firewalls, NAT, QoS, and collect measurements.
