Towards a Unified Network Slicing Model

Abstract

Network Slicing (NS) is actually an ongoing standardization work, different visions and inconsistent use of terminologies are observed across Standard Developing Organizations (SDOs). In this paper, we aim at presenting and comparing most well known works about NS information models. The target is to combine major contributions from different SDOs and come out with a proposition of a unified NS model. The proposed NS model components and the way they relate to each other are then mapped to the end-to-end Management and Orchestration (MANO) reference architecture.
