ECMP is a traffic routing application for Fattree network, switching packets with static hash algorithm. It is implemented for fattree4 and fattree8 here, using OpenFlow 1.3.0. It can work without a SDN controller.

Download files into Ryu directory, for instance, 'ryu/ryu/app/ECMP' is OK.

The usage of ECMP is simple, just start up the network as below:

$ sudo python ryu/ryu/app/ECMP/fattree4_ecmp.py

If the network has started up, test the correctness of it:

mininet> pingall
mininet> iperf
