Multiple logical networks, satisfying different service leve) reqllirements can be deployed on the same infrastructure. Each of these logical networks can be described as a network service descriptor as defined by ETSI NFV. AJthough ETSl NFV defines support for physical network functions and for deployments across muJtiple datacenters, network services are taken to a new leve) of scale in SG network slices. ln this paper we describe issues caused by this leve) of scale and which have to be solved when describing and deploying a SG network slice as a network service (NSaaS). We also describe how these issues have been tackJed in the SG-TRANSFORMER project.2engNetwork slicingOrchestrationconference posterTelecomunicacionesopen access
