<br>
First thanks to all developers and maintainers for the 1.2.5 release.<br>
<br>
I also have the pleasure to announce an update for my multipath version.<br>
The main changes are:<br>
<br>
- link-local addresses now works well,<br>
<br>
- add loss ratio computation for each path, and use it to limit the<br>
global loss ratio,<br>
<br>
- simplification of the sending procedure.<br>
<br>
The incoming loss ratio compution is based on the path sequence number<br>
with a 64 bits sliding window, and the outgoing loss ratio is received<br>
from the remote peer. For this purpose, I took 8 bits of the flag field<br>
in the network protocol.<br>
<br>
The paths are still ordered and selected by RTT, but multiple paths can<br>
be used to send the same packet (duplicates), to achieve a configurable<br>
maximum loss ratio (the -m option), which defaults to 0. If you set it<br>
up to 10(%), and if your 3 best (RTT) paths have an estimated loss ratio<br>
of respectively 30, 20 and 0%, then only the two firsts will be used,<br>
having together a loss ratio estimated to 30% * 20% = 6% < 10%.<br>
<br>
Remark that paths with a loss ratio estimated to 100% are used, except<br>
if they are idle for too long. This allow us to set the loss ratio to<br>
100% on new paths: it's particularly usefull at the beginning, where all<br>
paths are used together. Idle flows are quickly discarded.<br>
