MultiPath TCP (MPTCP) allows a host to use multiple interfaces to transfer data. Without knowledge of the characterisitcs of each network path, the MPTCP stack has to send data to learn those characteristics. This document communicates network characteristics using Port Control Protocol(PCP) to allow the MPTCP stack influence its functions.
