master socket and subsockets #306

Closed FiratA closed 5 years ago

FiratA commented 5 years ago

Hello Guys,

i have a question. How can i see, which sockets are available for MPTCP (subsockets). Is there a list?

When i use iperf, then i easly can find out the addresses through tp. But before a transmission, how can i find them out?

Hi,

I am not sure the understand the question.

Are you talking about this list?

/proc/net/mptcp_net/mptcp

Thank you for your fast reply, i found out that they can be found in mpcb master_sk and mpcb->connection_list. I have one more question, how can i assign them a IP address, because i know which ip address i am using on which interface, and i want to identify the socket based on the ip address?

OK, I didn't get you were asking where to find that in the source code.

I have one more question, how can i assign them a IP address, because i know which ip address i am using on which interface, and i want to identify the socket based on the ip address?

Where do you want to do this assignment? From a userspace application using bind? Or from a new path manager using mptcp_init[46]_subsockets? Do not hesitate to share code because I guess you saw how big was the MPTCP implementation ;-)
