Hi,
I tried to ask a question for TCPLS during the presentation, but gave up
due to time constraints. So, I just sent it here before my memory expires...

In my understanding, the advantage of MPTCP is it's in the TCP stack so
that it can have fine-grade packet scheduling and path management.
But, in case of TCPLS, I'm not sure how it can control multiple TCP
connections effectively.

For example, I am wondering how TCPLS finds the failure of connections or
which packets have been considered lost at the TCP layer without delay.
Can you provide some more info about this point?

Thanks,
