3.4.1

(N)-address

A name unambiguous within the OSIE which is used to identify a set of (N)-service-accesspoints which are all located at a boundary between an (N)-subsystem and an (N + 1)-subsystem in the same open system.

3.4.2

(N)-address-selector

(N)-selector

An element of addressing information that identifies a set of (N)-SAPs which are all in the same (N)-subsystem; an (N)-selector value is assigned by the local administration.

Note 1 to entry: The concept of (N)-address-selectors only applies above the Network Layer

3.4.3

(N)-association

A cooperative relationship among (N)-entity-invocations.

Note 1 to entry: This may be formed by the exchange of (N)-protocol-control-information.

3.4.4

calling-(N)-address

A parameter which may appear in an (N)-service request or indication primitive and which identifies the (N)-address at the (N)-initiator.

Note 1 to entry: In the service definition of a particular layer, such a parameter may be referred to either as a"calling-(N)-address" or"source-address". Throughout this Specification, however, only the term"calling-(N)-address" is used.

3.4.5

called-(N)-address

A parameter which may appear in an (N)-service request or indication primitive which identifies the (N)-address at the (N)-recipient.

Note 1 to entry: In the service definition of a particular layer, such a parameter may be referred to either as a"called-(N)-address" or"destination-address". Throughout this Recommendation | International Standard, however, only the term"called-(N)-address" is used.

3.4.6

descriptive name

A name that identifies a set of one or more objects by means of a set of assertions concerning the properties of the objects of the set.

3.4.7

(N)-directory-function

An (N)-function that processes (N)-addresses, (N − 1)-addresses, (N)-entity-titles, and (N)-PAI to provide mappings among these categories of information.

3.4.8

(N)-entity

An active element within an (N)-subsystem embodying a set of capabilities defined for the (N)-layer that corresponds to a specific (N)-entity-type (without any extra capabilities being used).

Note 1 to entry: This definition of (N)-entity is different from that in ITU-T Rec. X.200 | ISO/IEC 7498-1. This definition is the definitive one and will be moved to ITU-T Rec. X.200 | ISO/IEC 7498-1 to replace the existing definition when ITU-T Rec. X.200 | ISO/IEC 7498-1 is revised.

3.4.9

(N)-entity-invocation

A specific utilization of part or all capabilities of a given (N)-entity (without any extra capabilities being used).

Note 1 to entry: This definition will be moved to ITU-T Rec. X.200 | ISO/IEC 7498-1 to replace the existing definition when ITU-T Rec. X.200 | ISO/IEC 7498-1 is revised.

3.4.10

(N)-entity-title

A name that is used to identify unambiguously an (N)-entity.

3.4.11

(N)-entity-type

A description of a class of (N)-entities in terms of a set of capabilities defined for the (N)-layer.

Note 1 to entry: This definition will be moved to ITU-T Rec. X.200 | ISO/IEC 7498-1 to replace the existing definition when ITU-T Rec. X.200 | ISO/IEC 7498-1 is revised.

3.4.12

generic name

A name of a set of objects.

Note 1 to entry: A generic-title is a specific form of generic name.

3.4.13

(N)-initiator

An (N)-entity-invocation which issues an (N − 1)-service request primitive.

3.4.14

name

A linguistic construct which corresponds to an object in some universe of discourse.

3.4.15

naming-authority

A registration authority which allocates names according to specified rules. Where the naming-authority allocates titles, it is known as a title-authority. Where the naming-authority allocates addresses, it is known as an addressing-authority.

3.4.16

naming-domain

The set of names that are assignable to objects of a particular type. Where the names are titles, the set is known as a title-domain. Where the names are addresses, the set is known as an addressing-domain.

3.4.17

naming-subdomain

A subset of a naming-domain, which is disjoint from all other naming-subdomains of that naming-domain.

3.4.18

primitive name

A name that identifies an object and which is assigned by a designated naming-authority. The internal structure of the name is not required to be understood or to have significance to users of the name.

3.4.19

(N)-recipient

An (N)-entity-invocation which receives an (N − 1)-service indication primitive.

3.4.20

(N)-protocol-addressing-information

(N)-PAI

Those elements of (N)-PCI which contain addressing information.

3.4.21

responding-(N)-address

A parameter which may appear in an (N)-service response or confirm primitive and which identifies the (N)-address at the (N)-recipient.

Note 1 to entry: In the service definition of a particular layer, such a parameter may be referred to either as a"called-address" or"responding address". Throughout this Recommendation | International Standard, however, only the term"responding-(N)-address" is used.

3.4.22

(N)-service-access-point-address

(N)-SAP-address

An (N)-address that is used to identify a single (N)-SAP.

3.4.23

subnetwork-address

An identifier assigned to a subnetwork point of attachment by the registration authority of the subnetwork.

3.4.24

synonymous name

synonym

A name that identifies an object that is also identified by another distinct name. Synonymous generic names are distinct generic names that name the identical set.

3.4.25

system-title

A name, unique within the OSIE, which is used to identify a single real open system.
