09:00 - 10:30
This session will present the status of IPv6 adoption, Lessons learned from 4 years deployment of DNSSEC and challenges facing NRENs in terms of increasing user demand from the WiFi roaming service called eduroam.
Constructing networks in extreme environments like the Arctic regions challenges the technologies used. This session considers that challenges from two extreme points of view; that of building a sensor network for monitoring the Arctic climate in an extreme and difficult to reach location, and that of planning a submarine cable passing through the Arctic region.
Campus Issues 1
This session focuses on the use of technology on campus, with emphasis
on video, synchronous communication, and cloud services. Common
threads are coherency, security, and user friendliness.
The state of IPv6 adoption
After the World IPv6 launch and RIPE being on their last /8, where are we with IPv6 deployment? This talk will take a look at a collection of IPv6 statistics from the Internet, that Cisco has collated. How is Cisco doing on IPv6? Are we eating our own dog-food or spending all our resources on IPv4 life extensions?
DNSSEC: from root to (brown) leaves: Lessons learned from 4 years of active deployment
In the past 4 years, DNSSEC has catapulted from niche technology to the latest & greatest Internet security solution. More than 2 years ago, the root zone was signed, and many (cc)TLDs (representing ~80% of all domain names) now support DNSSEC, bringing the technology within the reach of the majority of domain name owners. The road so far has been bumpy and littered with the occasional roadkill. This talk will give a brief overview of how we got where we are, what we have learned, what has gone and goes wrong and what the future will bring.

Wireless Connectivity for Education: eduroam and beyond
The NREN community has created a superb WiFi roaming service for their community called eduroam. There is no reason to lean back and relax however: users are becoming more and more demanding, to an extent that their expectations can't be fulfilled by eduroam alone. What's happening in the WiFi space that can enable eduroam to become more than it is today? How will connectivity solutions for academic users look like?
Autonomous Wireless Sensor Networks in the Arctic
We will report on the lessons we learned deploying
wireless sensor networks in the arctic in the context of the MANA
project at Zackenberg, and in the context of the INTERACT project - an
FP7 infrastructure project federating european, as well as russian and
canadian arctic stations.
Planning a submarine cable in the Arctic - the NYAAL cable
UNINETT has got funding for a submarine cable between Longyearbyen
and Ny-Ålesund, both at Spitsbergen. The talk focuses on challenges
related to submarine cables in an extreme environment with icebergs,
sea bottom trawling, risk at landfalls, sensitive and vulnerable
wildlife and cultural heritage.
Wireless Sensor Networks Applications: if they work in Africa, they will work anywhere
A Wireless Sensor Network (WSN) is a self-configuring network of small sensor nodes communicating among themselves using radio signals, and deployed in quantity to sense the physical world. Sensor nodes are essentially small computers with extremely basic functionality. They consist of a processing unit with limited computational power and a limited memory, one or more sensors, a radio communication device and a power sour
Wireless sensor networks in Developing Countries have a great role to play not only to expedite novel solutions that help mitigate development problems, but also to facilitate research activities in crucial scientific areas such as environmental monitoring and energy management. The solutions found when designing sensor networks for Developing Countries can be used in Nordic countries, where the climate is harsh.
Some of the issues addressed include:
? Power consumption is an important issue for the network to be self-sustainable.
Minimizing the cost of deployment is of paramount importance. Since WSN is a nascent technology, many of the existing general purposes solutions in the market are expensive and/or they are not well tailored for use in the developing world.
To be usable in large numbers in developing countries, where climates are extreme and spare parts are rare, sensor nodes must also be rugged and reliable. Enclosures are needed to protect nodes from moisture and heat, but still expose sensors to the outdoor conditions that they are monitoring. As such, the environmental conditions must be taken into account when designing the system.
We will describe some WSN applications we have been involved in, highlighting how the solutions developed can be used in other harsh environments as well. The applications have to do with Solar Energy Monitoring, Irrigation and Air Quality.
During the presentation, we will demo some of the solutions we developed.
Building video infrastructure for eCampus
Flexible learning, as well as research collaboration, is depending on a coherent video infrastructure spanning from the local device to the mega-databases. The Norwegian initative eCampus is putting video solutions in place: collaboration tools, lecture capture, video-as-learning-process, mobile video. This talk presents the architectural work and working example solutions.
The messy future of synchronous communication
Making sense of H323, Lync, SIP, web conferencing, Skype and the rest
The Norwegian higher education community uses a variety of tools to facilitate synchronous online communication: audio & video calls, group calls, webinars etc. Our tool box is well equipped with mobile phones, a national SIP infrastructure, H323 video conferencing, Microsoft Lync, web conferencing tools (AdobeConnect), free tools (Skype), etc.
While all these tools offer similar functionality, they differ substantially on many aspects: historical background, the basic problem they address, market positioning, price points, deployment strategy, supported platforms, technology and more.
In the years to come we will need to deal with this wide variety of tools as none of them is going to go away any time soon. No one single tool addresses the various use cases well enough at an interesting price point to make that happen, there's always some pesky "little" detail in the way. Compounding this is the lack of community consensus and synchronised timelines. Existing investments and the FUD caused by expected market changes (HTML5! Google! Facebook!) top it off.
All this is of little interest to those trying to get their job done: students, lecturers, researchers and staff who want "stuff that works" that doesn't cost them an arm and a leg.
They expect us to come up with the answers. This talk will explore how the current tools for synchronous communication relate to one-another from a user-centric and the institutional/national service delivery point of view. It will mix user experience, technical and business considerations.
The talk will make some educated guesses about future directions, based on two years experience with the problem space through the Norwegian eCampus project, a national effort to take the technical infrastructure needed for net-based learning and research to the next level.
Supporting Cloud and Collaboration Scenarios with OpenConext
In The Netherlands, many campuses are eager to move services into the
Cloud. Cost reduction and better user experience are among the drivers
for this process. It is however not easy to combine these remote
services with the on-campus services in a coherent, secure and user
friendly way. At the same time institutions also struggle with
supporting Collaboration scenarios. Dealing with (international) user
level collaborations in research and education pose a significant
challenge. The same is true when engaging in collabortions between campuses.
This presentation showcases the work that has been done within SURFnet
in the past years to support the above scenarios. Several pilot and
production level usecases will be presented as these became possible
when SURFnet created the OpenConext collaboration platform.
