Automated Composition of Data-Path Functionality in the Future Internet
Modern networks not only forward traffic, but also perform a variety of processing operations on packets (e.g., content inspection, transcoding and QoS scheduling). Such data-path functionality needs to be composed suitably to ensure correct operations and adherence to policies put in place by different entities in the Internet. Currently, there exists no explicit support for describing the semantics of packet processing services, for composing these services, and for ensuring that policies are considered. In the authors' work, they propose a novel system for representing data-path functionality and policies in such a way that per-connection configurations can be composed automatically.
