Our Canadian Connection
- CANARIE as peer - CANARIE is Canada's Advanced Research and
Innovation Network - Pioneers on user controlled light paths and dark
fiber that formed the basis for SURFnet’s nationwide network
- CANARIE en SURFnet founding fathers (o.a.) of the Global Lambda Integrated Facility (GLIF)

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

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

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

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

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

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
