The creation, deployment and management of network architecture is manual, ad hoc and slow to evolve to meet new service requirements resulting in costly and inflexible deployment cycles. In the Genesis Project (email@example.com), Columbia University, we envision a different paradigm where new network architectures are dynamically created and deployed in an automated fashion based on the notion of spawning networks, a new class of open programmable networks. Spawning networks support a virtual network operating system called the Genesis Kernel that is capable of profiling, spawning, architecting and managing distinct virtual network architectures on-the-fly. In this paper, we describe a kernel plug-in module called virtuosity for the management of multiple spawned virtual networks. Virtuosity exerts control and manages multiple spawned virtual network architectures by dynamically influencing the behavior of a set of resource controllers operating over management-level timescales.
