Guest Editors' Introduction: Special issue on efficient management of SDN/NFV-based systems - Part II

Abstract

In Part I of the special issue, the main reported research contributions were: efficient resource allocation and management of softwarized network functions, design of highperformance platforms to allow network function virtualization on commodity machines, and enabling efficient collaboration between providers in softwarized networks. From the twenty six submitted papers, four papers had been selected for Part I of the special issue. An additional set of four more papers have been accepted for this Part II, after a thorough revision by the authors to take into account the detailed comments from the reviewers. The four selected papers in Part II of the special address three very important topics for the efficient management of Software-Defined Networking/Virtualized Network Functions-based (SDN/NFV-based) telecommunication systems: (i) optimizations to flow-based software-defined networks to address the scalability and energy consolidation requirements, (ii) programming abstractions in wireless software-defined networks, and (iii) improved network virtualization to more efficiently support latency sensitive applications.
