This document discusses how the RINA framework supports network slicing through connectivity and performance isolation. It allows sharing of network resources while managing risks like security, costs, and ensuring high resource utilization. RINA isolates connectivity and performance at all layers through management of associations and quality of service. It also supports the flow of information needed to construct and manage network slices. RINA offers simplification through separation of concerns and code reuse, lowering total cost of ownership. It can be incrementally deployed and provides a coherent architecture for software-defined networking and network functions virtualization.
