8.2.5 Application capability
Application capability contains network service functions. The network service functions in the application
capability do not include user applications that only send and receive messages among communicating
network users. Instead, the network service functions are functions to implement and control application
specific network behavior.

9 Security considerations
DAN provides mechanisms to guarantee secrecy, integrity, and availability of NDOs, and to verify the owners
of NDOs by means of the capabilities described in clause 8.2.3. To operate the mechanisms properly, an
additional mechanism to distribute cryptographic keys may be required.
Revealing the NDO access history by NDO consumers is an intrinsic problem in DAN where NDO names are
expected to be long-lived. Even if the name itself does not reveal the content of the NDO, the name can be
used to retrieve the NDO and the content may be known.
The new network function, caching, potentially poses new security threat to network users. For example,
placing improper NDOs in cache prevents access to the correct NDOs, forcing cache to store improper NDOs
reduces cache efficiency, etc.

10 Environmental considerations

The environmental considerations in this Recommendation are mainly subject to those provided by DAN as
specified in [ITU-T Y.3033]. Additional energy reduction by DAN may come from the processing capability
provided by DAN elements. The processing capability can be used to reduce the amount of data and the
number of messages to be transferred over DAN. Although the processing increases energy consumption at
one DAN element, reduction in the number of messages being exchanged lowers energy consumption in the
other DAN elements, which result in energy reduction in the entire network.
