Multipath TCP in the Linux kernel, beyond robots.txt, web performance, high frequency trading and the communication network of the Tudors
The implementation of Multipath TCP continues to be improved in the mainstream Linux kernel. With Multipath TCP, the packets that belong to a single connection can be exchanged over different paths. For example, a smartphone can use both Wi-Fi and cellular for a single connection. This enables seamless handovers for mobile applications and improves user experience. With Multipath TCP, a TCP can use both IPv4 and IPv6 and dynamically select the best performing address family in real time. If you have not yet enabled Multipath TCP on your Linux hosts or servers, check https://www.mptcp.dev, the website of the Multipath TCP maintainers in the Linux kernel.
