1. Defining the scope of the ccNSO

A functional DNS model
Function 1: Registering data (DRF)
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 DRF
New entries in the database
Change of existing entries e.g.
Change of technical data
Transfer
Cancellation

4. Bart Boswinkel, Shanghai ICANN Meetings
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.
Preventing single point of failure
Automatic recovery of failures etc.
Using up to date and appropriate technology

5. Model for the DNS from a ccTLD perspective
DNS is hierarchical
First level or the ROOT
Second level or the ccTLD
Third and lower or level user

6. Distribution of responsibilities
Vertical distribution
Horizontal distribution

7. Vertical distribution
Responsibilities level 1
Data registration function (IANA dbase)
Name server function (ROOT)
Responsibilities level 2 (ccTLD dbase/NS)
Data registration function (ccTLD dbase)
Name server function (ccTLD NS)
Responsibilities level 3
Data registration function (domain name data)
Name server function (domain name NS)

8. Horizontal distribution
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

9. Defining the scope of the ccNSO
ccNSO policy role in
Level 1 data registration function (IANA dbase)
Level 1+2 name server function (ROOT server and ccTLD NS)

10. 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.
