Core network aspects 1

• NDO availability:

DAN is required to provide a mechanism to ensure that the NDOs published in networks are
available for authorized consumers.
• NDO origin authentication:

DAN is required to be equipped with a mechanism to examine and confirm the authenticity of the
owners of NDOs.
• NDO name verification:

DAN is required to be equipped with a mechanism to examine and confirm the mapping between
an NDO and its name or ID.

• NDO integrity:
DAN is required to be equipped with a mechanism to examine and confirm the data integrity of NDOs.

7.5 Management
[ITU-T M.3400] defines the standard network management functions and DAN is also required to provide the
similar management functions, which include:
• Performance management
• Fault management

• Configuration management
• Accounting management
• Security management
DAN specific management functions are expected to be required. One of the potential DAN specific
management functions is the function to manage NDOs. The NDO management function may include
monitoring and regulation of NDO accesses and the number of NDOs, and withdrawal of NDOs. Further
development on DAN technologies is required before the requirements on DAN specific management
functions are defined.

7.6 Miscellaneous
• NDO cache function:
It is required that DAN elements can be equipped with cache that temporally holds NDOs to reduce
unnecessary duplicated transmission of the same NDO. The cache may be populated by NDOs either
passing by or allocated proactively.
• NDO fragmentation function:
It is required that DAN elements can fragment a large NDO into series of smaller units for network
transmission.
• Function of updating and versioning NDOs:
DAN optionally provides versioning capability to update a content while keeping its name.

7.7 Use case specific
• Processing function:
DAN optionally provides the capability to process NDOs before transmitting them in order to adapt
the NDOs to the capability of the receiving consumer or to aggregate information.
• Process registration function:
When processing function is available in DAN, it is required to have a mechanism to register the
description of process.
