Equal-Cost Multi-Path (ECMP) Implementation in ns-3

As a part of the MMPTCP project, I have implemented several ECMP modes in ns-3. These are random, per-flow (hash-based) and round-robin modes.

To demonstrate these ECMP modes I have made a few videos, you can find them as follows:

TCP with round-robin ECMP (YouTube)
UDP with round-robin ECMP (YouTube)
TCP with hash-based ECMP (YouTube)
TCP with random ECMP (YouTube)
TCP with no ECMP (YouTube)

Installations

Clone the ECMP's repository.

git clone https://github.com/mkheirkhah/ecmp.git

Configure and build the ns-3 simulator

CXXFLAGS="-Wall" ./waf configure build

Run a simulation

./waf --run "ecmp"

Note that we have written a simple simulation script to demonstrate how to use the ECMP modes available in this repository. You can find it in the scratch folder.
