  Abstract

Recently, the network infrastructure has been required to be expanded due to the increase of the traffic usage, but there are many difficulties in the existing network environment. In order to solve the difficulties, NFV abstracts all the types of network resources and enables software-based automatic management and control. Network Service (NS) of Network Function Virtualization (NFV) is composed of one or more Virtual Network Functions (VNFs) to support a specific network service. The NS describes all the relevant information as well as general information in Network Service Descriptor (NSD). In this paper, we first analyze the OASIS standard document of TOSCA-based NFV information modeling, and model the information necessary for NSD based on TOSCA, an information modeling language for cloud services and applications. We design and implement the defined NSD using Composer provided by Cloudify which is open source based cloud orchestration framework. Finally, the implemented NSD is deployed and validated on the OpenStack using Cloudify Manager.
