Heavy hitter detection is an important task in many network security and traffic measurement applications. In this work, we implement a heavy hitter detection accelerator based on the Count-Min sketch algorithm inside the NetFPGA-10G OpenFlow switch. By using only a small amount of extra memory and logic resources, the OpenFlow switch is capable of detecting the heavy hitter flows accurately without...
Sketch-based data streaming algorithms are used in many network traffic monitoring applications to obtain accurate estimates of traffic flow. However, the flexibility is limited as hardware implementation of sketch counters may not be re-used for different measurement tasks. In this paper, we develop a generic hardware infrastructure for collecting flow statistics. The purpose is to achieve the goal...
