Network function virtualization (NFV)
Software-defined networking (SDN) and Network Function Virtualization (NFV) have revolutionized the way networks are designed, built, and operated. This paper presents how an SDN system, Office Without a Cool Acronym (OWCA), was designed and implemented to build an enterprise network that is secure, testable, and automates all aspects of managing networking devices. OWCA requires explicit authorization before forwarding a packet from a source to a destination, ensuring that only authorized traffic is allowed on the network. It is intent-driven and modeling based.

Abstract—Network slicing (NwS) is one of the main technologies
in the h-generation of mobile communication and
beyond (5G+). One of the important challenges in the NwS
is information uncertainty which mainly involves demand
and channel state information (CSI). Demand uncertainty is
divided into three types: number of users requests, amount
of bandwidth, and requested virtual network functions workloads.
Moreover, the CSI uncertainty is modeled by three
methods: worst-case, probabilistic, and hybrid. In this paper,
