The Multipath TCP Daemon - mptcpd - is a daemon for Linux based operating systems that performs multipath TCP path management related operations in the user space. It interacts with the Linux kernel through a generic netlink connection to track per-connection information (e.g. available remote addresses), available network interfaces, request new MPTCP subflows, handle requests for subflows, etc.
