MPTCP is an extension 18to the standard TCP that allows multiple TCP streams over different network 19paths between the same source and destination. This can enhance bandwidth and 20improve reliability by using multiple paths simultaneously. 21 22MPTCP is beneficial in networks where multiple paths exist between clients and 23servers, such as mobile networks where a device may switch between WiFi and 24cellular data or in wired networks with multiple Internet Service Providers. 25 26This option is currently only supported on Linux starting from kernel 5.6. Only 27TCP connections are modified, hence this option does not effect HTTP/3 (QUIC) 28or UDP connections. 29 30The server curl connects to must also support MPTCP. If not, the connection 31seamlessly falls back to TCP. 32
