Deploying Use Case Specific Network Slices Using An OSM Automation Platform

Network slicing is a novel fifth generation (5G) concept that enables operators to create logical networks (slices), each dedicated to certain specific applications, on top of a common network infrastructure, computation and storage resources. These slices are logically isolated from each other with respect to network performance and security, providing services to vertical industries and various use cases. Accordingly, an orchestrator is needed in order to manage network resources for various slices. Among different orchestrators that have been developed, open source MANO (OSM) appears as a popular platform, providing a software stack for slice developers. In this paper, we present an implementation of deploying network slices based on the OSM automation platform and report preliminary experiments that have been performed. To validate our implementation, a specific media streaming use case has been selected and a slice with three pre-configured network services that contain a media server has been created.
