Structure of NSAP Addresses
Structure of NSAP Addresses
A Network Service Access Point address (NSAP) is the ISO-defined
Internet Address. It is used to identify real systems unambiguously on a
network. NSAPs are used by OTS/9000 in much the same way as ARPA
Internet addresses are used by TCP/IP.
There are several documents that may help you better understand this
section. Among them are:
• ISO 7498/AD3, Information Processing Systems - Open Systems
Interconnections - Addendum to the OSI Reference Model Covering
Naming and Addressing
• ISO 8348/AD2, Information Processing Systems - Data
Communications - Addendum to the Network Service Definition
Covering Network Layer Addressing
• ISO 9542, Information Processing Systems - Data Communications -
End System to Intermediate System Routing Exchange Protocol for
Use in Conjunction With the Protocol for the Provision of the
Connectionless-mode Network Service [ES-IS Protocol]
• ISO 10589, Information Processing Systems - Data Communications -
Intermediate System to Intermediate System Intra-Domain Routing
Exchange Protocol [IS-IS Protocol]

The structure for NSAP addresses discussed here has been formulated to
meet the following objectives:
• Provide a framework so that HP can recommend a management
strategy.
