5. Hybrid SURFnet6,
more than just Internet
- Over 10,000 km dark fiber
pairs, reaching all SURFnet
connected institutes (>180)
- (indirectly) Providing access
to over 1,000,000 users
(academics, students and
staff)
- Internet Connectivity of 1 and
10 Gbit/s, IPv4 en IPv6,
Unicast and Multicast
- Dynamic Lightpaths and
Optical Private Networks

7. Beyond fibers
- In the early days
- Pilot UMTS and GPRS at selected campuses
- Wireless Point-to-Point for fast rollout
- Today
- eduroam is a (almost) global confederated
wireless roaming service based on Wi-Fi
- Provided through the European collaboration of
36 national-level federations
- Hundreds of institutions are involved, the
majority of which own and operate the service’s
infrastructure

8. Trends in e-Infrastructure
- Science is becoming increasingly digital, needs to deal
with increasing amounts of data and computational needs
- Simulations get ever more detailed
- Nanotechnology – design of new materials from
the molecular scale
- Modelling and predicting complex systems
- Decoding the human genome
- Experimental Science uses ever more
sophisticated sensors to make precise
measurements
- Need high statistics
- Huge amounts of data
- Serves user communities around the world

11. Modern Research needs an
integrated e-Infrastructure
- Providing seamless access to and allowing the
shared use of:
- Computing and storage facilities
- Generic application services
- Sensors and instruments
- Network resources
- Providing hassle free end-to-end connectivity and a
single user interface and a single control plane for
the allocation of multiple resources, from multiple
domains and in multiple locations
- Close collaboration among providers and users will
be essential to create this environment

16. Our challenges
- Today’s Internet is not good enough to support the needed
e-Infrastructure for research
- No guaranteed services on a “best effort” network
- Fit for delay tolerant, many-to-many communication
- To support an e-Infrastructure Research networks will have
to do better...
- Provide guaranteed performance for large data flows and
time-critical applications
- Support increasingly heterogeneous access methods
- Take into account security and environmental issues
- … while keeping the successful end-to-end principle of the
internet
16 Canada Connects: Productivity on the Move – May 27, 2010 – ING House
17. Key Take Aways
- Multi-level approach to support true collaboration
- Need for ubiquitous broadband connectivity wired
and wireless for SURFnet’s contingency
- Bandwidth seen as free by users (academics,
students, and staff)
- Defragmented of middleware platforms
- High common-denominator of devices
- Ubiquity of mobile devices
- Standardization
