1 Core network aspects

8.2.1 Data capability

Data capability has functional blocks as follows:
 Forwarding function:
This functional block contains NDO name based forwarding function, request aggregation function,
and packet forwarding loop avoidance function.
 Cache function:
This functional block includes storage to cache NDOs and its accompanying control function.
 NDO repository:

NDO repository is the storage to hold original contents.
Additionally, application specific functional blocks may be placed in the data capability.

8.2.2 Control capability
Control capability has functional blocks as follows:
 Routing function:

Routing functional block is composed of NDO registration function, NDO location resolution
function, advertisement function for the availability of NDOs, and network selection function for
messages to reach an NDO.
 Mobility support function:
Mobility support function includes consumer mobility function, NDO mobility function, and network
mobility function.
 Forwarding information base:

Forwarding information base is the storage to hold information to determine the direction of
forwarding and is to be used by forwarding function.
 Publish/subscribe function:

This functional block includes publication and subscription functions.
Additionally, application specific functional blocks may be placed in the control capability.

8.2.3 Security capability
Security capability has functional blocks as follows:
 Access control function:
Access control function is a mechanism to secure data confidentiality that NDO is accessible only by
the authorized consumers.
 NDO authentication function:
NDO authentication function is a mechanism to secure data authenticity that NDO is claimed to be
true by an authorized entity.
 NDO integrity function:
NDO integrity function is a mechanism to examine and confirm the integrity of NDO that NDO is
ensured to be the same as the source.
8.2.4 Management capability

Management capability is the function block to provide network management functions. [ITU-T M.3400]
defines the standard network management function groups and DAN is also required to facilitate the
management functions defined in [ITU-T M.3400] which are:
 Performance management

 Fault management
