| DCN addresses
The system has two addresses in the DCN: • Ethernet address • NSAP address Ethernet address The Ethernet address is the unique 6-byte address of a network element. Sometimes it is also referred to as the hardware or physical address of the node. The Ethernet address has only local meaning on the LAN and cannot be used for routing purposes. It does not contain the information on where the node is in the data communications network. NSAP address The network service access point (NSAP) address is used by the network protocol for location information. The NSAP address of a node is its DCN wide identifier which uniquely identifies the node in the network.

Background The following three NSAP structures can be distinguished: • ISO DCC NSAP address format (fixed 20-byte address structure). This format is used by most Lucent Technologies network element types in the network. • Local Lucent Technologies NSAP address format (fixed 10-byte address structure). This format is also used by a number of Lucent Technologies network element types. • Flexible NSAP address structure. An alternative to the previous two formats. Although different NSAP address formats exist, preferably all nodes in a network should use the same address format. Metropolis ® ADM (Universal shelf) supports the ISO DCC NSAP address format (fixed 20-byte address structure), the local Lucent Technologies NSAP address format (fixed 10-byte address structure), and the flexible address structure. tải về 2.06 Mb.
