Standard object-oriented languages do not provide language support for modeling changing collections of interdependent objects. We propose that R++, an integration of the rule and object-oriented paradigms, provides a mechanism for easily implementing such models. R++ extends C++ by adding a new programming construct called the path-based rule. Such data-driven rules are restricted to follow pointers between objects, and are like ''automatic methods'' that are triggered by changes to monitored objects. Path-based rules encourage a more abstract level of programming, and unlike previous rule integrations, are not at odds with the object-oriented paradigm and offer performance advantages for natural applications.

Software defined networking (SDN) is being heralded as a major breakthrough for provisioning new services, commoditizing network hardware and reducing service provider capital and operational expenditures. Decoupling the control plane from the data plane has inherent advantages in terms of offering flexibility and presenting new service capabilities, but also presents operational and functional challenges. Such decoupling would create a new set of use cases, equipment, and network best practices that providers would have to imbibe in the near future. the key scope of this Feature topic (Ft) was to understand, from an implementation perspective, how SDNs can be implemented in very large networks using commodity gear or white boxes through use cases.
