NIPS ConferenceCreating synergies between networks at Member State level

ScenariosIntroduction
The scenarios are different possible ways of creating synergies 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.

ScenariosTechnical possibilities - Introduction
Three main technical layers have been selected, these form the 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

ScenariosTechnical possibilities – Fiber layer
The Fiber layer sharing scenario:
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

ScenariosTechnical possibilities – Transport layer
The Transport layer sharing scenario:
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 2 – Bit transport sharing: Shared bit transport, but each responsible for their own organisation of all other teleom functions

ScenariosTechnical possibilities – IP layer
The IP layer sharing scenario:
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.

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

What advantages and disadvantages do you see for each scenario?

ScenariosOwnership possibilities – Discussion
• Are the layers leased or actually owned?– 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?

ScenariosFinancing possibilities – Discussion
The financing aspect of the scenarios includes two different 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?

ScenariosGovernance possibilities – Discussion
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

Maintaining (Political) MomentumIntroduction
There are potential advantages in Public Administrations using a 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) MomentumDiscussion
Member State level:• 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?
