Multipath TCP (MPTCP) is an extension to TCP that allows + for the use of multiple network interfaces on a standard TCP + session. The addition of new addresses and scheduling of data + across these occurs transparently from the perspective of the + TCP application.

+ +

The goal of this project is to deliver an MPTCP + kernel patch that interoperates with the reference MPTCP + implementation, along with additional enhancements to aid + network research.

+ +

After a major re-design of the earlier prototype + implementation, the patch is again able to establish and carry + out multi-path connections that incorporate multiple addresses. + Improvements have also been made to path management and to code + handling the addition of subflows to a connection.

+ +

I have most recently added data-level re-transmission + support and am in the process of testing this. I will soon be + in a position to start more extensive testing of the patch in + different multi-path scenarios, with plans for a public release + of v0.5 in May.

Testing of data-level re-transmission.

Basic support for per-subflow congestion control + algorithm selection.

Testing and release of v0.5 patch.
