Calculation ofEnd to end delay in an AFDX network simulated on Omnet 4.2.2 IDE

[naj]

Hello all,

I started using OMNeT + + to evaluate the performance of an AFDX network.

I should calculate the end to end delay and the jitter in the network.

I started a small model: a message sent from an end system A to an end system B via a switch. I did the simulation and run. Here I have to calclulate the end to end delay; how to do it? is it possible to directly use IDE without code?

I have another question, how to configure the routing table in the switch. in fact, the AFDX network has a static routing.

Thanks

the sources of inet-framework (integration branch) register the end-end delay in the sca file

Just to avoid confusion: This is about AFDX networks which is not related to INET/INETMANET in any way.

If you are speaking about this: https://github.com/omnetpp/afdx

then this is just some code that could be used as a starting point towards a full afdx model. It is by no means a complete model, especially that the switch internals and routing are not modeled (it's just a dummy). So the answer to the question about configuring the routing table: you cannot (at least with this code).

This model was started by me out of curiosity but I have stopped working on it. If someone wants to pick it, i would be happy.

As for measuring end to end delay: the usual way is that the messages contain a timestamp of the creation time. When the message arrives the receiving module should emit a signal containing the difference between the current simtime and the creation time. You can use that signal to analyse jitter, delay etc.

But first you have to finish the model.

I saw the model of AFDX in https://github.com/omnetpp/afdx and I realize that this model is not complete. my project is to simulate the AFDX network to evaluate its performance. So I chose the simulator OMNeT + + and I hope this is the right choice. I just started and I have many questions.

if you can help me I will be reconnaisant

Hello Rudolf,

is that possible to import your model AFDX and complete it  in INET framework?

thank you

Any progress on your project related to the afdx model?
