Using Future Internet testbed in the classroom

About Future Internet

• Overcoming limitations of today’s Internet requires changing this architecture through the design called Future Internet (FI)

• Research FI consists of:– Discuss how the new architecture will be developed for the

Internet;– Evaluate alternative proposals for this new architecture;– Develop procedures to adopt the new architecture.

About Future Internet

• Providing environments for large scale experimentation requires:

• Coexistence with the network traffic of production;

• Environment should be flexible and programmable (software defined network) so that researchers can quickly define and validate their proposals

Testbeds for Future Internet

• Purpose• Experimental research into network infrastructure and

distributed applications• Above Layer 2

• Programmable network environment• Characteristics:

• Wide set of technologies and scale• Faithful to the scale and heterogeneity of the real environment• Wireless and sensor networks, routers, switches, end-hosts…

• Dedicated networks• Isolated from the production Internet and from each other• Use of virtual routers and multiplexing links between them

• Monitoring and Instrumentation of experiments

FIBRE: a large-scale Future Internet testbed facility• Studies began in 2008, inspired by GENI (USA) and by the FIRE

(Future Internet Research and Experimentation) program of the EU• Funding provided 2011-2014 by Coordinated Call in ICT between

Brazil and the EU, supporting FIBRE (FI testbed/experimentation between Brazil and Europe).

• FIBRE project includes 10 nodes in Brazil and 3 in the EU. • The follow-on FIBRE2 project is being funded in Brazil to support

the operation, maintenance and expansion of the existing testbed, for use by research and education until 2018.

• On-going conversations were initiated in 2013 to promote the international federation of the FI testbeds

• In 2015 AmLight deployed a Fibre island in Miami federated to FIBRE.

FIBRE in the classroom – Why?

• The use of a large-scale testbed give students first-hand experience to a real-world situation, instead of using software tools to simulate networks in the laboratory.

• With the use of Future Internet testbeds in computer-network classes, we believe the next generation of researchers will be more capable of dealing with architectural experiments and of continuously evolving the current Internet architecture

• But this is not a new idea…

Worldwide Initiatives in teaching in Future Internet testbeds

FORGE: Forging Online Education through FIREhttp://ict-forge.eu


NYU classroom-as-a-service (for wireless experiments)http://witestlab.poly.edu/site/page/classroom

Our plans in the medium-term

1. To select hands-on exercises used by professors to teach network classes• Based on Mininet and other tools• Based on OpenFlow

2. To deploy selected exercises in the FIBRE infrastructure and generate step-by-step instructions and video-lessons.

3. To create an online repository of teaching material for professors.

We welcome ideas of exercises/experiments to be ported to FIBRE

• Through FIBRE’s experimental facilities, researchers can validate and demonstrate new FI proposals

• Project is in its final steps• Small adjustments and tweakings in the infrastructure• Needs more experiments to validate the testbed
