Network Softwarization: Developments and Challenges

Review and analysis of recent advances in intelligent network softwarization for the Internet of Things

“…The goal is to transform the network into an open ecosystem that decouples hardware and software components. This transformation is expected to deliver benefits such as advanced services, enhanced networking capabilities, and improved network development and maintenance capabilities [28]. The following features show the importance of network softwarization: separation of responsibilities (by separating data and control planes), configurability and global view (by having a centralized controller), scalability (the ability to add and dynamically configure network functions as needed), cost efficiency (reduced CAPEX and OPEX), etc.…”

“…Both SDN and NFV technologies play an important role in enabling network softwarization and increasing programmability [7], along with other emerging technologies (e.g., cloud computing, edge computing, network slicing) [28].…”

An Overview of Machine Learning-Enabled Network Softwarization for the Internet of Things

“…The goal is to softwarize the network and transform it into an open ecosystem that dissociates the hardware and software involved in the network. This is expected to provide benefits in terms of advanced services, advanced networking capabilities, combined with network development and maintenance capabilities [14].…”
