[Babel-users] RTT-based metric merged

[Juliusz Chroboczek]

Dear all,

I've just merged into master Baptise Jonglez's work that implements an
RTT-based metric for Babel.  This is described in detail on

  http://arxiv.org/pdf/1403.3488v1.pdf

In short, this change enables using RTT in order to choose between
"good" and "bad" tunnels.  It is disabled by default, and can be
enabled by doing

  interface tun-42 enable-timestamps true

In order for it to be useful, you need to enable it on both sides of
the tunnel.  You can tune the parameters of the metric with the
rtt-min, rtt-max ans max-rtt-penalty parameters.

Any feedback will be warmly welcomed before I release 1.5.0, and
received with undisguised hostility after that.
