Abstract
In the context of NFV and agile service production, virtualization of resources and SFC play a key role in automating network services deployment. Designing NFV management and orchestration to provide dynamic SFC as a service is addressed by the proposed NFV orchestration framework.1 The framework is designed to facilitate the development of NFV architecture components with a focus on SFC orchestration, placement algorithms, required monitoring, and network services stitching. The proposed framework can be used to compare placement algorithms as well as develop and evaluate other service function chaining solutions using a variety of SDN controllers to interact with heterogeneous underlying networking technologies. This article presents the SFC orchestration framework, an implementation, and a qualitative and quantitative evaluation of its components in an experimental environment.
