Systems and methods are described for enabling routers to coordinate via a
back-channel communication medium. The information exchanged over the
back-channel is used to increase the number of paths considered for the
routers during route optimization. The Decision Makers may assert routes
and prefixes to the routers under their control. This may be done via a
Border Gateway Protocol (BGP) feed. The Decision Makers, in turn,
communicate separately with one another, in order to coordinate routing
policy amongst themselves. This coordination may be performed over a
back-channel, which may take the form of physical or logical connections
between the Decision Makers.
