Network Slice Provision Models
draft-homma-slice-provision-models-02
Abstract
Network slicing is an approach to provide separate virtual network
based on service requirements, and it's a key feature of the 5G.
3GPP has standardized the specifications for network slicing in the
5GS, but there are still some problems for realization of end-to-end
network slices. For complementing the lacks or expanding the
usability, several organizations are proceeding standardization.
However, the definitions and scopes of network slicing vary to some
degree from one organization to another. This document provides
classification of provisioning models of network slice for clarifying
the differences on the definitions and scopes.
