1.  Introduction

   Considering the business logic of network slicing as shown in Fig.
   Figure 1.  At the top layer, tenants describe the service that they
   want through a service model, and this service model dose not bind to
   any specific implementation technology.  At the bottom layer,
   multiple technologies are available to be used to support the network
   slicing service.  Between the common service model and lots of
   available implementation technologies, there is a gap which needs a
   technology independent information model.  During the implementation
   process, the most appropriate technology will be selected according
   to the SLA, and the management/operations on the information model
   also will be translated into the language understood by the select
   technology (or directly translated into a set of network parameters
   configurations).
