Chapter 13 Management Network Connectivity
13.6.3 OSI Connectionless Network Service
CLNP uses network service access points (NSAPs) to identify network devices. The CLNP source and
destination addresses are NSAPs. In addition, CLNP uses a network element title (NET) to identify a
network-entity in an end system (ES) or intermediate system (IS). NETs are allocated from the same
name space as NSAP addresses. Whether an address is an NSAP address or a NET depends on the
network selector value in the NSAP.
The ONS 15454 supports the ISO Data Country Code (ISO-DCC) NSAP address format as specified in
ISO 8348. The NSAP address is divided into an initial domain part (IDP) and a domain-specific part
(DSP). NSAP fields are shown in
Table 13-8
. NSAP field values are in hexadecimal format. All NSAPs
are editable. Shorter NSAPs can be used. However NSAPs for all NEs residing within the same OSI
network area usually have the same NSAP format.
