Control Plane Stability from Incomplete Information

Interdomain routing protocol stability depends on the absence of policy conflicts between autonomous systems; but since most policy is kept private, it is hard to ensure that conflicts are avoided. We show that even limited information can be used to help guide network (re-)configuration, by automated tools that assist network operators. This work is based on an underlying formalism of partially specified policy configurations, which has related applications in network optimization, resilience, and giving insight into design choices.
