Equal Cost MultiPath (ECMP) implementation - INET4.2.1

[lakshmikrish-97]

Hi all!

I am new to OMNeT++ and INET framework. I am looking to run some data center network simulations and was wondering if there exists any implementation of ECMP module for routing flows in a data center network setup?

Following on this thread!
Besides, I was wondering if any kind of multipathing has been added to the Inet framework?

[heychr]

hello, can you please let me know if you got an answer? is there any multipath routing added to inet or omnet?

A Google search gave me this repo: https://gitraap.i3a.info/jfclemente/ecmp. "ECMP INET 4.4"

hello, i am having trouble to build this framework, does it work for you?

We recently added ECMP to opp_env's database, so if you are on Linux or macOS (or use WSL on Windows), you can install it along with with OMNeT++ with a single command:

opp_env install -w ecmp-workspace --init ecmp_allinone

Then you can go grab some coffee or tea and enjoy it while opp_env downloads the packages, unpacks them, and compiles the projects. Then change into the new ecmp-workspace/ directory, and enter

opp_env shell

to get a shell prompt where you can work with the ECMP model.

This installs from: https://github.com/inet-framework/inet-clos-ecmp/. The following commit contains all the contributions the ECMP model makes to INET-4.4.1: inet-framework@2f5644c

You can grab opp_env from here: https://github.com/omnetpp/opp_env#opp_env-automated-installation-of-omnet-simulation-frameworks.

Hi M. Andras, does the framework support ECMP on L3; I'm trying to work on my BSc. research that compares RIP, OSPF and ECMP OSPF I'm using OMNet++ to carry out this research.

Thanks,
Jay

We are not the maintainer or author of the project. We made it available for easier installation in opp_env, but we do not have any insight about the implementation or suitability for any purpose. You should try to install it and try to figure out whether that's suitable for you (or contact the original author)

Hello M. Andras, thank you I will try this, currently I am trying to implement a RL model for multi-path routing, can you please let me know how the output of the agents (weights of the links) can be applied on the simulation? What is the parameter that can be responsible to apply the action received from the agents? I would really appreciate your insights on this because I am using Omnet++ in my PhD, thank you, Christina
