2. CloudNext: Federated Testbed for Cloud Computing experimentation

▼

   

Description

Virtualization has played a major role in experimental testbeds. While this approach fulfils the need of many researches, some demand direct access to hardware (e.g., when the research target is the hardware itself or the virtualization infrastructure, or when the testbed virtualization interferes with the research outcome). CloudNEXT (Cloud ComputiNg EXperimental Testbed) is an experimental testbed capable of offering baremetal resources as well as customized Cloud Computing clusters that aims to fulfill the needs of these researches. It is currently being deployed in Brazil, with integration with Brazil’s main Future Internet testbed (FIBRE).

3. CloudStor Strategy: Data Movement -> Storage -> Compute

▼

   

Description

AARNet’s strategy for research data started with its “staple”, moving data, and introduced FileSender which proved an instant success. Researchers quickly requested more permanent storage, leading to the release of CloudStor, a sync-and-share system for storing data in the cloud, whose uptake was equally meteoric. But users were not content. They wanted a data ecosystem that included tools to move, store, visualise, manage their data, and finally to process that data – these were added, culminating in Jupyter Notebooks to manage the whole data lifecycle: moving, storing and processing data. We believe NRENs must expand their vision in this way.

7. GN4-3 WiFiMon - Crowdsourced Performance Measurements

▼

     

Description

WiFiMon is based on eduroam or IEEE802.1X-enabled campus wireless networks. WiFiMon measures, records and exports statistics regarding network performance (latency, bandwidth). These measurements are correlated with user identity (Radius Logs) and location, i.e. the Access Point they are connected. Measurements are triggered by users (mobile clients) when they visit WiFiMon-enabled websites and/or using WiFiMon-enabled mobile applications. Crowdsourced and traditional, deterministic measurements from appropriately placed hardware probes are combined to generate performance statements from various mobile clients. This hybrid approach provides the “best” data sets, which are applicable to address technical and strategic issues and predict the network's future state.

11. MMCFTP’s data transfer experiment over 4 x 100 Gbps lines between Japan and Europe

▼

Description

Advanced research projects build large experimental devices under international collaborations, and share huge measured data with distant research partners.Therefore, high-speed academic network and long-distance fast data transfer methods are critical for research efficiency. NII and GÉANT provide such academic network services for research communities in Japan and EU, respectively.

NII has developed a fast data transfer method, MMCFTP (Massively Multi-Connection File Transfer Protocol) for advanced research projects. MMCFTP uses several thousands of TCP connections to sustain the specified target speed, and controls the number of TCP connections dynamically according to the network condition, including the RTT and packet loss rate in real time. In TNC17, MMCFTP demonstrated 131 Gbps data transfer over 2 x 100Gbps lines between London and Tokyo via USA [1].

Recently, two international 100 Gbps routes between Japan and Europe are established. One is SINET5 Tokyo-Amsterdam 100 Gbps line. The other is a route combining the SINET5 Tokyo-Singapore 100 Gbps line and the CAE1 Singapore-London 100 Gbps line. CAE1 is a joint project of AARNet, SingAREN, TEIN*CC, NORDUnet, SURFnet and GÉANT.

In TNC19, we will try data transfers between Tokyo and Amsterdam over these four 100 Gbps lines (Figure 1), as a collaboration activity of NII and GÉANT.

12. Non-web federated access with OIDC

▼

     

Description

The FEUDAL service can provision accounts on remote non-web services, create and assign users, and provide necessary user information. It presents a way for real-time asynchronous and dynamic management of credentials, e.g. SSH keys, and user information necessary for non-web access, like group info.

The oidc-agent application is a set of tools to manage OIDC tokens and make them easily manageable from the CLI. Oidc-agent can communicate with trusted components (such as web browsers), which users may use to authenticate with the OIDC OP, and obtain an access token, which may “pass” to desired applications.

15. Realization of an effective multi-factor authentication environment based on risk base in Shibboleth

▼

     

Description

An integrated authentication infrastructure based on Shibboleth have been operated in Kanazawa University. Because password authentication is no longer safe, I decided to introduce a multi-factor authentication.

But I need to consider two points. The first point was that multi-factor authentication takes more time than password authentication. The second point was that if users don't have a specific possession, they can't authenticate. So I have realized a risk-based authentication mechanism that requires multi-factor authentication in certain specific situations. By requiring multi-factor authentication only when the user accesses the important SPs from “Outside”, security enhancements can be realized without compromising convenience.

16. Self protection of the critical infrastructure

▼

     

Description

We present two approaches to the protection of the backbone optical infrastructure against unwanted and unpredictable fibre cuts. They both rely on pure optical signal rerouting where the information of optical disturbance is shared via OSC between Czech Light devices. In general, the solution is a L0/L1 mechanism for imminent fibre cut detection. The mechanisms are not only able to detect the real fibre cut faster than upper protocols, but have the ability to detect the fibre cut even before it actually happens. Both methods are using special optical signals embedded in the fibre along with other optical (data) channels.

17. Take out what you can: Quantitative Analysis of the Open Question Results from the National Student Survey

▼

     

Description

Fontys, with 44.000 students one of the largest universities of applied science in the Netherlands, participates in the annual National Student Survey (NSS). The NSS consists of many items, asking students to rate their satisfaction and ends with an open question. The free-format answers are currently not processed because it is too labour-intensive.

The goal of this study is to automate the analysis of the NSS free-format answers using Natural Language Processing. After cleaning the text data (e.g. delete stop words, names and inappropriate language) both topic and sentiment analysis with state-of-the-art tools were carried out. The results provide valuable insights.
