Abstract
The development trends of networking and wireless communications technologies have evolved toward Open Networking (ON), Software Defined Networks (SDN), Network Function Virtualization (NFV), and Disaggregation. ON and SDN/NFV are playing the key roles for softwarization and virtualization (S&V) of next generation networks such as 5 th Generation Communications and Networks (5G) and Internet of Things (IoT). This article explores the S&V of 5G & IoT and addresses the challenging issues related to applying SDN/NFV to 5G and IoT. These issues include system performance, end-to-end interoperability, software compatibility, global deployment, integration of SDN and NFV , and shortage of talents. In addition, we describe the research and development status of adapting ON architecture and applying SDN/NFV to 5G and IoT in Taiwan. Finally we report the collaboration between National Chiao Tung University (NCTU) and networking industry in the areas of programmable switches built on top of silicon with Programming Protocol-independent Packet Processor (P4) high-level script language and prototyping an OpenAirIntrface (OAI)-based M-CORD.
Highlights
The open source software executed on the commodity hardware in the control plane can be very complex, which consist of controller [17][19], Network Function Virtualization (NFV), and Cloud OS
The other papers [6][9][10][11]are investigating how to take care of 5G or mobile broadband. We address both of Internet of Things (IoT) and 5G from softwarization and virtualization point of view
The software and tools of open source related to Software Defined Networks (SDN) will continue to update or revise and the virtualization of network elements defined in NFV may change or update time to time
Summary
Among them P4 is a high-level programming language designed to configure/re-configure hardware, CORD is the architecture to transform telecommunications central offices to becoming data centers and ONOS [20] is the open networking OS developed by ONF. The ecosystem of this ON community includes network service operators, network equipment vendors, silicon providers, and white box ODM providers become so active. Network softwarization and programmability promise to reduce OPEX and to provide better flexibility and bring new services to their customers sooner [21]
