…andshake finishes. The maximum amount is governed by TCP's congestion control [ RFC5681 ]. 4. The client sends an ACK acknowledging the SYN and the server data. If the client's data is not acknowledged, the client retransmits the data in the ACK packet. 5. The rest of the connect…

…s of a duplicate ACK; these are usually only sent as a signal of a lost segment RFC5681 in regular TCP. Therefore, an MPTCP implementation receiving a duplicate ACK that contains an MPTCP option MUST NOT treat it as a signal of congestion. Additionally, an MPTCP implementation SH…

…e conservative rate (e.g., TCP collapses the congestion window to one segment [ RFC5681 ]). Some applications require an initial latency estimate before the latency between endpoints can be empirically sampled. For instance, when arming a retransmission timer, an initial value is…
