However, the meaning and understanding of the network slicing concept are different from each other and there is no common definition. The present document does not d

48、efine network slicing use cases or features but references external SDOs and Foras definition and concept of network slicing within the context of each individual SDO/Fora. Clause 4.2 shows relevant external bodys documents which introduce and define network slicing, and describes related details pr

49、ovided in NGMN, 3GPP, and ONF. It also describes the possible relationship with the NFV constructs. Clause 4.3 describes NFV and SDN relation in a multi-tenant and multi-domain environment in term of network slice deployment. 4.2 Concepts defined by SDOs and Fora and NFV architectural framework mapping 4.2.1 Potential relevant SDOs and Fora Table 4.2.1-1 describes relevant SDOs and Fora and their documentation which introduce and define the concept of network slicing.
