between networks at Member state level
Four main aspects need to be considered:
• Technical – What technical layers can be shared?
• Ownership – Who owns it?
• Financing – Which parties finance what and how?
• Governance – Who governs what parts and how?
The technical perspectives are the first consideration, but influence
both ownership, financing and governance, it is important to keep
this in mind.

basis for the technical scenarios, the levels to which technical
infrastructure can be shared, creating synergies:
• Fiber layer sharing scenario
• Transport layer sharing scenario
• IP layer sharing scenario
These scenarios refer to sharing of dark fiber (what currently is dark
fiber – if it is used, it will of course become lit fiber)
Let’s take a closer look

At a technical level it only extends to the sharing of (dark) fibers.
The separation is in this case on physical level: every party has its
own wavelength on one shared fiberpair

Scenario 2 – Bit transport sharing: Shared bit transport, but each responsible for their own organisation of all other teleom functions
At a technical level it extends to the sharing from fiber down to the
level of bit transport. The separation is in this case on electrical
level: every party has its own electrical interface on a shared
DWDM solution, which are interconnected by a shared fiberpair.

Scenario 3 – Complete sharing: Sharing completely down to routed packet transport with a seperated route for each, but shared
equipment, each only responsible for access to ensure the packets are transported in a closed user group
At a technical level it extends all the way from sharing the fiber to
routed packages. The separation is in this case on logical level:
every party has its own logical interface on a shared routed
network. The different packets are logically separated by tags on
every packet.

What advantages and disadvantages do you see for each scenario?

Scenarios
Ownership possibilities
Scenarios
Ownership possibilities – Discussion
• Are the layers leased or actually
owned?
Click
to edit Master title style
– What is your approach?
– What is the best approach?
• What if some layers are leased and others owned, how does this
affect ownership of the network?
• Is there a need for a separate organization that owns/leases the
shared parts and makes these available to the different network
owners (centralized ownership)?
• What are the likely benefits of shared ownership?
– Security?
– Cost savings?
– Reliability?

elements:
• Which parties are responsible for financing what?
– Does everyone pay for the shared parts?
– If so, how to define the level each network owner has to pay for
the shared parts?
– If it is centralized, should it be funded centralized and should there
be contributions from public administrations?
• How can this be financed?
–

Centralized national budget?
Public administration’s own budgets?
Specialised funds and programmes?
Structural funds?

Scenarios
Governance possibilities
Scenarios
Governance possibilities – Discussion
Click to edit Master title style
The governance possibilities will depend greatly upon the chosen
technical scenario and on the financing model that is chosen:
• The technical scenario dictates what should be governed.
• The financing model dictates who is involved.
The question is how it should be governed and how the different
stakeholders at Member State level should be represented

network with a closed user-group:
• Security advantages – Sensitive and personal data is/will be
exchanged by PA (think of PRISM accessing your personal data)
• Availability advantages – High availability is needed for public
administrations to be able to work
• Bandwidth advantages?
There are also advantages in creating synergies between Network
Service Providers and Public Administrations:
• Cost saving or cost sharing
• Others?

Maintaining (Political) Momentum
Discussion
Member State level:
Click to edit Master title style
• What can be done at Member State level to encourage synergies
between networks?
• How can we build and maintain the political moment and focus
on this?
EU level:
• What can be done at EU level to encourage synergies between
networks at Member State level?
• How can we build and maintain the political moment and focus
on this at EU level?
