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.

+ +

A v0.51 release has been tagged in our repository, with + some minor improvements over v0.5.

+ +

We have now removed much of the MPTCP code that was inside + the functions tcp_do_segment, tcp_output, and + other code used for standard TCP connections. The goal of this is + to restrict the added MPTCP code to just MPTCP connections, + leaving regular TCP connections using the existing code.

+ +

We are currently in the process of implementing a subflow + socket buffer upcall and event processing. These will handle + changes in subflow socket state, MP-signalling, and incoming + data segments.

+ +

This also requires some re-working of the MP option + processing, particularly how incoming DSN maps are parsed and + stored for use during MP-layer reassembly.

+ +

We are also looking at how our changes might take advantage + of the new TCP stack modularisation enhancements to create + subflow-specific TCP functions.

+ + + + The Cisco University Research Program Fund at Community + Foundation Silicon Valley + + + + The FreeBSD Foundation + + + + +

Complete the implementations of subflow event processing + and new option parsing.

+ + + +

Update documentation and task lists.
