- BIG Science Data sources
- High Energy physics, (CERN, ESS)
- Astronomy, (Radio antennas and
telescopes)
- High performance computing
- GRID projects

- Many in non technical disciplines use
standard IaaS cloud services to get ad hoc computing resources
- Data from sources and repositories
connected to NREN networks count for 10-15% of traffic… And is only relevant for less than 1%
- f the users

What about the rest?
- + 80% of data repositories used in
research is on the internet
- Universities is outsourcing everything
from email to survey tools to basic server and services,, to the cloud
- Teachers use cloud tools to do network
simulations… not to mention collaboration tools media and streaming,,, in the cloud

What about the rest?
- High quality access to the internet is
the most important network service for the majority of researchers and other users
- How do we secure that we deliver
what the 100% of our users want?

What can you do as a NREN
SLIDE 8
NORDUnet
Nordic infrastructure for Research & Education
What to do?
- Peer directly with, or connect directly
to the major content providers and social media..
- Be involved in major outsourcing deals
to ensure that network connectivity is part of the selection criteria,, to save money and gain quality
- Don’t rely on standard IP Transit
connectivity, it is strangled,,
SLIDE 9

Do (settlement free) peering?
- Cost
- Predictability
- Reachability
- Not being dependent on 3rd party
network agreements
- Quality
- Reduced RTT - the most common
customer request for improvement
- Not just having 2 BGP sessions
controlling your connection to the rest
- f world

What can you do as an NREN
- Connect to your local in country IX
20% peering
- Get connectivity to the major IX’s in
Europe, AMSIX, LINX, DCIX,, 60% peering
- Get connectivity to the US and connect
to locations, east, west, middle and south,,
- it will take 3-4 years, but will mainly be cost neutral

wikipedia
Software defined networking (SDN) is an
emerging architecture for computer networking. SDN separates the control plane from the data plane in network switches and routers. Under SDN, the control plane is implemented in software in servers separate from the network equipment and the data plane is implemented in commodity network equipment. OpenFlow is a leading SDN architecture.
- Thus SDN allows for
- quick experimenting and optimization of
switching/routing policies, and for
- external access to the innards of switches and
routers that formerly were closed and proprietary.

GÉANT Bandwidth on Demand (BoD) is a service for dynamic
bandwidth provisioning across multiple networks, enabling users to instantly create dynamic point-to-point circuits through a web-based user interface.

Both is part of the SDN puzzle But If Openflow isn't the solution, What is the problem?
