Hi,

I am happy to announce that Linux MPTCP version 0.2 has been released.
You can download it here: http://inl.info.ucl.ac.be/mptcp
It is still dependent to IPv6 (I am currently working on adding v4 
support). Here are the changes from release 0.1:

 * Upgraded patch to Linux kernel version 2.6.28
 * DSN option as defined in draft v02. Except that we use absolute instead of
relative subflow seqnums, until it proves useful to change this.
 * Data reinjection: Upon RTO, we try to retransmit on a faster subflow. This
allows recovering from failures.
 * Same receive window advertised on all subflows: Failing to do this may lead
to subflow deadlocks in some cases.
 * Changed multipath scheduler: The previous one had no sending buffers. This
one uses the same dynamically tuned buffers (Van Jacobson '98) as normal TCP
flows, and for each segment, the buffer with lowest filling ratio is selected.
This tries to fill all the pipes with the same proportion.
 * For a detailed view of the changes, explore the git tree here : https://scm.info.ucl.ac.be/trac/mptcp/browser

regards,

Sébastien.
