+ <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>The v0.5 patch was released, which is the first patch
+ of the re-written implementation. We are in the process of
+ documenting the new design and addressing some feedback as
+ provided from the community.</p>
+
+ <p>Work has commenced on improved input handling, as the current
+ method of receiving and reassembling segments has been the cause
+ of some instability/stalls during connection shutdown. This will
+ involve re-using the subflow receive buffers and an upcall to
+ enqueue a MP-layer reassembly task without the need to take a lock
+ on the MP control block. The improvements should also allow
+ bypassing <tt>mptcp_usrreq</tt> for standard TCP connections.</p>
+
+ <p>The MPTCP commit history was synchronized with
+ hg-beta.FreeBSD.org, and have made the repository available on
+ BitBucket (see links). Future patch releases will be tagged
+ there. The tree is now merged with &os; head weekly. An updated
+ v0.51 patch is ready for release.
