+ <body>
+ <p>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.</p>
+
+ <p>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.</p>
+
+ <p>A v0.51 release has been tagged in our repository, with
+ some minor improvements over v0.5.</p>
+
+ <p>We have now removed much of the MPTCP code that was inside
+ the functions <tt>tcp_do_segment</tt>, <tt>tcp_output</tt>, 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.</p>
+
+ <p>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.</p>
+
+ <p>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.</p>
+
+ <p>We are also looking at how our changes might take advantage
+ of the new TCP stack modularisation enhancements to create
+ subflow-specific TCP functions.</p>
