  BGP is vulnerable to a series of attacks. Many solutions have been proposed
in the past two decades, but the most effective remain largely undeployed. This
is due to three fundamental reasons: the solutions are too computationally
expensive for current routers, they require changes to BGP, and/or they do not
give the right incentives to promote deployment.
  In this abstract we propose a Software-Defined Networking (SDN) architecture
to secure BGP routing. Our solution, BGPSecX, targets an IXP and it includes
techniques to allow different IXPs to collaborate. With SDN we remove the
computational burden from routers and do not make changes to BGP. Targeting
IXPs and promoting inter-IXP collaboration enables the creation of incentives
to foster adoption of BGP security services.
