This repository includes the P4 implementation of the CoNEXT 2020 paper FCM-Sketch: Generic Network Measurements with Data Plane Support.

Currently, the prototype P4 source code is written in both P4-14 and P4-16, and compiled using version 8.2.0 and 9.2.0 of BF_SDE, respectively.

FCM-Sketch supports both various in-network (data-plane) and control-plane queries.

• Data-plane queries:
  • Flow size estimation
  • Heavy hitter detection
  • Cardinality
• Control-plane queries:
  • Flow size distribution
  • Entropy

In addition, Heavy change detection is avaialble entirely in the data plane if we keep multiple sketches with resource trade-off.

Please use the description in the corresponding directory.

Data-Plane queries are supported in P4-16 implementation. In future, we will provide a PTF test for EM-algorithm. Actually, it is easy to extend; we can load register values, sync with simulator's data structures, and run the algorithm.
