Establishing PDCA cycles for agile network management in SDN/NFV infrastructure
Shibata Kotaro, Nakayama Hiroki, Tsunemasa Hayashi, Shingo Ata · 2015
Software Defined Networking (SDN) is attracting many researchers in networking area, especially in the field of network operations and managements. A fine-grained network management that controls traffic dynamically by the unit of flows is one of the key challenges towards a resilient network for the future Internet. To this end, the network is required to re-configure timely, adaptively and dynamically. In this paper, we propose a self-adaptive approach to manage both network and functional resources in SDN. To achieve the quick adaptation to various pattern of traffic, we first establish a Plan-Do-Check-Act (PDCA) cycle for our network management architecture. Then we describe a detailed procedure including interactions from networking components. We also show some use cases and give a proof-of-concept deployment.
