Core network aspects 1

 NDO producers

 NDO consumers
 DAN elements

 DAN realms
When there are multiple DAN realms, the DAN elements connecting heterogeneous DAN realms act as
gateways to make appropriate conversion of names, IDs, protocols, etc. so that the DAN realms can
communicate to each other.

Figure 1 – Overall network structure of DAN.

8.2 Capabilities
DAN is composed of the capabilities described in Figure 2. There are five major capabilities: Data capability,
Control capability, Security capability, Management capability, and Application capability. The capabilities
can be further subdivided into functional blocks as shown in the figure.
