Modern networks not only forward traffic, but also perform a variety of processing operations on packets (e.g., content inspection, transcoding, QoS scheduling). Such dataplane operations cannot be easily coordinated in the current Internet architectures since there is no explicit policy support for packet processing services. As more diverse systems and protocols are deployed in the next-generation Internet, this problem becomes increasingly challenging. In the authors' work, they propose a novel policy enforcement system for data-path functions in the next-generation Internet. Using a formalism to represent policies and automated planning tools, connection request can be adapted to meet the policy requirement of the domains they traverse.
