# `--mptcp`
|
||
|
|
|
||
|
|
Enables the use of Multipath TCP (MPTCP) for connections. MPTCP is an extension
|
||
|
|
to the standard TCP that allows multiple TCP streams over different network
|
||
|
|
paths between the same source and destination. This can enhance bandwidth and
|
||
|
|
improve reliability by using multiple paths simultaneously.
|
||
|
|
|
||
|
|
MPTCP is beneficial in networks where multiple paths exist between clients and
|
||
|
|
servers, such as mobile networks where a device may switch between WiFi and
|
||
|
|
cellular data or in wired networks with multiple Internet Service Providers.
|
||
|
|
|
||
|
|
## Usage
|
||
|
|
|
||
|
|
To use MPTCP for your connections, add the `--mptcp` option when using `curl'.
|
||
|
|
|
||
|
|
## Requirements
|
||
|
|
|
||
|
|
This feature is currently only supported on Linux starting from kernel 5.6. Only
|
||
|
|
TCP connections are modified, hence this option does not effect HTTP/3 (QUIC)
|
||
|
|
connections.
|
||
|
|
|
||
|
|
The server you are connecting to must also support MPTCP. If not, the connection
|
||
|
|
seamlessly falls back to TCP.
|
||
|
|
|
||
|
|
## Availability
|
||
|
|
|
||
|
|
The `--mptcp` option is available starting from `curl` version 8.9.0.
