This protocol can be mixing between reactive and proactive processings
which is not stable which is not reliable, see the draft mentions:
Routers in the same network may choose either proactive or reactive multipath
calculation independently according to their computation resources.

I think the protocol must only support one calculation for each path,
making mixed reactive and proactive per path is not stable. While we know
that OLSRv2 is a proactive protocol so if we use source routing as in this
protocol it should do only reactive calculation that makes it stable in the
dynamic-networks like manet. IMHO, using reactive and proactive
independently seems strange in manet routing environment. I advise to look
into conditions of its theories because it seems that this multipath
routing in for fixed-wireless-networks not for manets.
