Introduction

Uses a counting bloom filter to block flows for which the switch has observed more than a certain number of packets (default 1000).

How to run

Run the topology:

sudo p4run

Run the receiver and the sending scripts in h2 and h1 respectively:

mx h2
python receive.py 5000

Send 1500 packets using the same 5-tuple. Only the first 1000 will be received by h2.

mx h1
python send.py 10.0.2.2 5000 1500
