TNC15 - CONNECTED COMMUNITIES

BibTeX

Connected Communities

TNC15, its 31st edition, was hosted by FCT | FCCN, Portugal's unit for the operation of the National Research and Education Network within the funding agency for science and research in Portugal, between 15-18 June 2015 in Porto. The conference provided an opportunity for researchers, operators and suppliers of research and education networks in Europe and beyond to meet, present and discuss their latest results and requirements in an ideal environment for promoting collaboration

This year's conference theme was "Connected Communities”. From the start NRENs have been in the business of connecting, not only campuses to each other and to the rest of the Internet but also people belonging to many different communities. Today, NRENs find themselves at an exciting crossroads in society. Not only do they provide the basic network infrastructure on which big science and big data build, but they also address the requirements of ever-increasing and more diverse communities of Internet end users in the wider research and education areas.

Conference summary

The conference series that has lead to TNC15 has been at the heart of developments in research and education networking for around three decades. Decision makers, technical experts, solution providers and users gather to share views and help shape the future of networking.

"Connected Communities” is not only the theme of this year's conference but also necessary to support world leading research and education which drives our community to develop innovations to support this diverse collaboration.

Six plenary speakers addressed many different and thought-provoking topics related to the conference theme.

In Monday's opening plenary, John Day, from Boston University, opened the conference with the topic Connected Communities Need Strong Foundations exploring how the Internet developed without the benefit of architectural insights and how, without a strong architecture model, the community collaboratively developed the infrastructure we use today.

Two important aspects related to the big data community were addressed by Manfred Laubichler and Sarah Kenderdine in Tuesday’s plenary. Manfred Laubichler uses signal theory on collaboration networks to detect hotspots of innovation, whereas Sarah Kenderdine shows how cultural heritage and access to it can be enriched by associating digital objects with real life artifacts. Both show in their own way how the smart use of large data collections and fast networks can lead to new insights and ways to look at the world.

Wednesday's plenary session covered two separate topics. Firstly, Timo Lüge of Social Media for Good spoke about how the he increased availability of mobile Internet access around the world is connecting people, organizations and communities like never before in changing lives and relationships, and how it has a significant impact on how information flows in the case of natural disasters. The second presentation of the day was given by Avis Yates Rivers of the Technology Concepts Group, who described our Unconscious Biases, taking a close look at the myth of meritocracy in tech and what steps can be taken to broaden the participation of underrepresented groups.

João Paulo Cunha, Associate Professor at the Department of Electrical and Computer Engineering of the Faculty of Engineering of the University of Porto presented Porto as a Living Lab for Future Internet. Combining the ubiquity of wireless and mobile data with a large sensor network detailed improvements that big data mining has had on the community. Concluding the conference with the power of being connected and combining multidisciplinary and multi-institutional partners in a project focused on Porto highlighted the societal benefits of Connected Communities!

Selected Papers Summary

Nine papers presented in parallel sessions were selected for this publication. These papers cover both research and practical approaches to some of the challenges faced by today's research and education networks. In keeping with the conference theme, one thing they have in common is connecting communities through service expansion, data, research, communication and collaboration.

The first of these, “Extending eduroam into South African townships” by Guy Halse of Rhodes University in South Africa contrasted the digital divide of good access to ICT on campus juxtaposed with little to no Internet access once students return home. This case study covered the technical and political challenges, some of which are specific to the location, for the lower than expected deployment of a service with great public value leaving the audience with a model for future deployments to avoid similar mistakes in their own environment.

"Comprehensive security framework for COPERNICUS:Open Data Access" by Gioacchino Buscemi, Barbara Angelucci, Michele Di Mascolo, Manuel Nardelli and Aldo Damiani addressed the important topic of ensuring the confidentiality, integrity and availability of the open data resource from the ESA COPERNICUS programme through the development of a security framework.

In "DynPaC: Dynamic and Adaptive Traffic Engineering for SDNs", by Jasone Astorga, Alaitz Mendiola, Aitor Urtasun, Eduardo Jacob, Mariví Higuero and Victor Fuentes, the authors presented an adaptive and fault tolerant provisioning system for connectivity services on top of an SDN/OpenFlow infrastructure implemented by extending the Open Daylight Project.

A multi-country development was presented by Xavier Jeannin with participation from Tomasz Szewczyk, Bojan Jakovljevic, Thomas Schmid, Dave Wilson and Brian Bach Mortensen titled "Multi-Domain Virtual Private Network service" showing the design and deployment of a Virtual Private Network service for GÉANT, NORDUnet and 15 NRENs (AMRes, BELnet, BREN, CARNet, DFN, Funet, FCCN, GARR, GRNET, HEAnet, HUNGARnet, PSNC, RedIRIS, RENATER, SUnet), this truly collaborative service between NRENs is able to deliver a bundle of services: Layer 3 VPN (IPv4, IPv6), point-to-point Layer 2 VPN and multi-point Layer 2 VPN and its application for connectivity between clusters, research groups, grids, cloud centres and HPC centres supporting the distributed European scientific community.

The paper "Implementing NRENs in land locked African Countries" by Douglas Kunda and Bonny Khunga from Zambia presents how improved research and publication opportunities for Universities and Research Institutions in Africa have increased through the availability of Internet bandwidth, collaborative research tools and availability of resources through e-libraries. The challenges for landlocked countries in Africa, outlining the critical success factors that need to be implemented in order to address these challenges were also explored.

"Automated provisioning of Ethernet OAM: the case of GRNET" by Leonidas Poulopoulos, Yannis Mitsos, Michalis Mamalis and Stauros Kroustouris describes a novel network automation framework developed in-house by GRNET NOC for the the monitoring of Layer 2 network operation via a set of functions that enables detection of network faults and measurement of network performance, as well as distribution of fault-related information.

Two papers in the session "The Future for Video Conferencing” were presented. The first of these is a paper entitled "“Rendez-Vous”: Web(RTC) Conference as a Service" by Franck Rupin from RENATER, France. This covered the existing video conferencing solutions deployed in our environment and how the R&E community can avoid the constraints of past technology and bring affordable video conferencing services to the masses.

The second paper, by Michael Stanton, Leandro Ciuffo, Shinichi Sakaida, Tatsuya Fujii, Hiroyuki Kimiyama, Junichi Nakagawa and Hisao Uose, called: "8K Live Television Coverage of Global Sports Events in Brazil". This presented the collaboration between RNP of Brazil and NHK of Japan and the use of the global R&E backbone network to provide Super-Hi Vision (SHV) media streamed to sites around Brazil and Japan engaging a wide community in the 2014 FIFA World Cup showing the collaboration between end sites and the extensive preparations for efficient and effectively lossless media transmission over the intermediate networks.

The final selected paper was presented in the topic "High-speed access to data from sensors and seismic stations using CAREN for Earth Observation in Central Asia" in a session called "Applications that transcend the globe". Askar Kutanov from CAREN showed how high-speed networking brings Central Asia into the Global Climate Change monitoring community.

Archives of live–streamed speeches, speakers’ slides and other TNC15 information are all available via the conference website: tnc15.terena.org. We look forward to very warmly welcoming you to TNC16, which will be held on 12-16 June 2016, Prague, Czech Republic, and at tnc16.geant.org.
