Hi Mami.. I will try the approach that you suggested..

This is exactly what I want to do… I plan to send a tracer packet just before sending the file and after sending the file… and check my file transfer time.. I will be there at KNIT7 and if I could not figure out how to timestamp and check packet then I will definitely be in contact with the team working on it..

Thanks 🙂

Hey Mami.. I checked the link that you shared but I could not find instructions for using owl for MF slice. The link that you provided prepares a non MF slice for owl. My slice is already MF slice so I am not sure if it works for me.

I have another question.. I am not sure if you can help me with that. So in my experiment I am transferring a file from one node(on site 1) to another node(on site 5).. passing the file through some intermediate nodes on site 2, site3 and site 4. I want to calculate the precise time for my file transfer from site 1 to site 5. I am not sure which FABRIC measurement facility I can use to calculate this. It will be of great help if you could guide me in the right direction on how to achieve this (maybe you can share a link to some content about such functionality or some link to jupyter notebook about such functionality will be highly appreciated).

Thank You

No I did not create a new slice…
Thanks Hussam, I will create a new slice and get back to you if I get into any issues..

Hi Arash,
This is the output I get when I run it in the terminal

Hi I tried to install the latest fabrictestbed-mflib using the command

%%bash
