Section: 28.14 Data Network Access Identifier (DNAI)
Content: A Data Network Access Identifier (DNAI) is an operator defined identifier of a user plane access to one or more DN(s) where applications are deployed (see clauses 3.1 and 5.6.7 in 3GPP TS 23.501[ System architecture for the 5G System (5GS) ]  [119]). The same DN may also be referred to by multiple DNAIs. DNAI is represented as an operator specific string (see clause A.2 in 3GPP TS 29.571[ 5G System; Common Data Types for Service Based Interfaces; Stage 3 ]  [129]. The format of the DNAI is defined by the operator and is not standardized.
