A functional DNS model

Function 1: Registering data (DEF)
Function 2: Run a name server and keep it
running (NSF)
The two functions are linked by generating a
zone file
At every level of the DNS these functions have
to performed

Closer look at NSF


NS function is to ensure interoperability and
stability of the DNS
To achieve this
–
–
Best current technical practices as described in
RFCs and auxiliary documents
Maintain resilience by e.g.


–
4
Preventing single point of failure
Automatic recovery of failures etc.
Using up to date and appropriate technology

Model for the DNS from a ccTLD
perspective

Policy role: meaning the ability and power to define a
policy
Executive role: meaning the ability and power to act
upon and implement the policy; and
Accountability role: meaning the ability and power to
hold the responsible entity accountable for exercising
its power

Framework for Analyses


Combining these two perspectives, policy and
functions, the following framework emerges
The framework presented offers the possibility to
–
–
Delineate and identify specific policy areas;
Identify and define roles with regard to these specific policy
areas.
NB. the delineation of the specific policy areas one has to
be aware of the trade off between precision/granularity
and practical use.
