Abstract. Controller applications in OpenFlow cannot be trivially
augmented to support the various high availability
(or failure recovery) models of server
applications. Recent work on OpenFlow has largely assumed
static replica configurations or has relied on
controller developers to embed high availability
support in their design. Instead, we present
RuleBricks, a system for flexibly embedding high
availability support in existing OpenFlow
policies. RuleBricks introduces three key
primitives: drop, insert, and reduce. We describe
how these primitives can express various flow
assignment and backup policies, demonstrating the
one offered by the Chord protocol. We have
implemented RuleBricks and the Chord assignment
policy. Using simulation, we compare RuleBricks
against a typical tree-based approach. We show that
RuleBricks maintains linear scalability with the
number of replicas on the Chord ring.
