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.
