Note: Multihoming is s the practice of connecting a host or a computer network to more than one network. For example, usage of 5G and WLAN simultaneously

Note2: MPTCP is compatible with standard TCP - we can use MPTCP without multipath-options, and it will work like regular TCP.

Note3: MP_CAPABLE: client and server tell each other tokens, that partners should use to create a subflows

Note4: MP_JOIN: client use Token of server, and server use Token of client

Note5: MP_CAPABLE(MY TOKEN) and MP_JOIN(PARTNERS TOKEN)

Note6: Packets in MPTCP has two sequence numbers: 1) “local” sequence number - sublow sequence number that TCP uses to find duplicates and missing packages insode a flow data transmission (like normal single-connection TCP sequence numbers), and 2) “global” sequence number, that will be used to reconstruct original data sequence. Only flow-specific sequence numbers wold be not sufficient.
