Few undergraduates have pinned down their post-graduation plans as precisely as senior Carolena Ruprecht. Just after commencement on June 3, 2016, Ruprecht will attend a Reserve Officer Training Corps (ROTC) commissioning ceremony, and then be whisked off to her commission as a surface warfare officer, destined to serve on an aircraft carrier. There, she will lead an elite crew responsible for maintaining and operating the ship’s nuclear-powered systems. “I have always been driven to do as much as I can with everything I do,” Ruprecht says. “In eighth grade, I began looking into the [U.S. military] academies, and the idea of combining my abilities in math and science with service really appealed to me.” During high school, her academic interests settled quickly on nuclear engineering: “It seemed like a cool and exciting challenge to produce so much energy from a small amount of material, as if you were unlocking some secret of the universe,” she says. Ruprecht was decisive about college, too. “My goal was MIT,” she says, because of its engineering strengths. For officer training she chose the U.S. Navy, with its “great nuclear program” powering a fleet of ships and submarines. The fact that she’d grown up on the Jersey shore “loving being near water” clinched the decision. When she arrived in Cambridge in 2012, Ruprecht quickly discovered she would be contending with more than the usual rigors of undergraduate life. “I’ve felt like an ordinary student while in classes, but I have extra responsibilities that probably most other students don’t have,” she says. While pursuing her degree in nuclear science and engineering, Ruprecht must also drill daily as a Navy midshipman. Like other MIT students, she’ll do homework until midnight or so and then be up at the crack of dawn for physical training. “The hardest part,” she says, is that “no one else has to wake up at 5 a.m.” After spending the first few years of her major focused on science and theory, Ruprecht is excited to be plunging into reactor engineering and design courses. She is engaged in an undergraduate research project using the DANTE electrostatic accelerator in MIT’s Vault Laboratory for Nuclear Science (part of the Center for Science and Technology with Accelerators and Radiation), which offers her a much-sought opportunity for hands-on engineering experience. Under the supervision of Dennis Whyte, MIT Department of Nuclear Science and Engineering head and director of the Plasma Science and Fusion Center, Ruprecht is building filters for the accelerator’s particle beam. Her project is part of a much larger investigation of applications for the DANTE accelerator, which was originally designed to produce neutrons for cancer therapy studies. Ruprecht’s filter sits at the front end of a 12-foot-long tube through which a beam of ions is accelerated, with voltage determining the velocity of the ions. Ruprecht’s filter is intended to exclude certain kinds of ions, while admitting others. “The purer the beam, the better the data,” she says. The information Ruprecht collects as she measures cross sections of the beam will eventually be incorporated in her senior thesis. Although the going has been slow, with the accelerator balking at times, Ruprecht has been thrilled to build the filters, using magnets, soldering iron, wires, and screws, and to install them in the accelerator. “I learned the science and did the calculations in class, but it is so cool to see how things work, or don’t, in real life,” she says. Her focus now is on practicing what she has learned, and readying herself for a leadership role managing a nuclear reactor on a Navy ship. “I will be making sure it’s running right, delivering power the ship needs, and is safe,” she says. This spring she will learn the name of the ship to which she is assigned. Ruprecht imagines this job will be “challenging,” but she can imagine nothing more gratifying than “being part of the Navy program, on the nuclear side of things.” She hopes someday to return to school for a master’s degree, and get involved somehow in sustainable energy in civilian life. “I’d love to participate in building a nuclear reactor on time, within budget, and delivering power to lots of people,” she says. But school is not in the cards in the foreseeable future. “It’s hard for me to sit still,” says Ruprecht. “I’m definitely ready to spend time out of the classroom, to go out and start practicing what I’ve learned.”

26 May 2016 | Cambridge, UK and Tokyo, Japan: Over 50 million researchers, academics and students across Europe and Japan are set to benefit from a direct 20Gbps (gigabit per second) connectivity injection into the pan-European GÉANT network, celebrated yesterday at the launch event of the upgraded Japanese Science Information Network (SINET5) in Tokyo. The capacity boost comes in response to the increasing data transfer requirements of collaborative research between Europe and Japan on projects such as the ITER energy fusion reactor, the Large Hadron Collider (LHC) experiments and the worldwide e-VLBI radio-astronomy network. During his keynote speech at the launch Steve Cotter, CEO GÉANT, said: “Up to now, connections between GÉANT and SINET have been achieved by peering in North America. Now, SINET is bringing 20Gbps directly to GÉANT; this means that we can jointly support European and Japanese researchers in their cutting-edge scientific endeavours with faster and higher capacities as well as lower latency. We expect to see a major ramp-up of traffic exchanged over our networks as further EU-Japan user projects come to fruition in the next 2-3 years.” Operated by the National Institute of Informatics (NII), the 5th generation of the SINET network commenced operation in April. Shigeo Urushidani, Director of the Cyber-Science Infrastructure Development Department at NII commented: “With its 100Gbps full-mesh backbone, SINET5 opens up new possibilities for 3 million users at over 800 connected universities and research centres across Japan. Enhanced international connectivity, including a direct connection to Europe, is a vital element of SINET5’s strategy to support our user communities and to advance global scientific research.” The two 10Gbps circuits connect with the GÉANT network in London where NII’s network equipment is supported at GÉANT’s new data centre at Slough, UK. SINET5 also connects there to the GÉANT Open exchange which enables direct links with other research and education networks. GÉANT and NII retain a back-up interconnection in New York. The relationship between GÉANT and NII is longstanding. NII has been a major partner from the outset in TEIN, the EU-funded Asia-Pacific research and education network established by GÉANT and now successfully connecting 20 countries in the region. NII remains a major partner in TEIN and currently connects to the TEIN network in Singapore. About GÉANT GÉANT is Europe’s leading collaboration on network and related infrastructure and services for the benefit of research and education, contributing to Europe's economic growth and competitiveness. The organisation develops, delivers and promotes advanced network and associated e-infrastructure services, and supports innovation and knowledge-sharing amongst its members, partners and the wider research and education networking community. GÉANT has 41 member countries and is owned by its core NREN membership, and also has Associate members including commercial organisations and multi-national research infrastructures and projects.

Finding the root-cause of a network security anomaly is essential for network operators. In our recent work, we introduced a generic technique that uses frequent itemset mining to automatically extract and summarize the traffic flows causing an anomaly. Our evaluation using two different anomaly detectors (including a commercial one) showed that our approach works surprisingly well extracting the anomalous flows in most studied cases using sampled and unsampled NetFlow traces from two networks. In this demonstration, we will showcase an open-source anomaly-extraction system based on our technique, which we integrated with a commercial anomaly detector and use in the NOC of the GÉANT network since late 2009. We will report a number of detected security anomalies and will illustrate how an operator can use our system to automatically extract and summarize anomalous flows.

Although network security is a crucial aspect for network operators, there are still very few works that have examined the anomalies present in large backbone networks and evaluated the performance of existing anomaly detection solutions in operational environments. The objective of this work is to fill this gap by reporting hands-on experience in the evaluation and deployment of an anomaly detection solution for the GÉANT backbone network. During this process, we analyzed three different commercial tools for anomaly detection and then deployed one of them for several months in the 18 points-of-presence of GÉANT. We first explain the general requirements that an anomaly detection system should satisfy from the point of view of a network operator. Afterwards, we describe the evaluation of the tools and present a study of the anomalies found in a continental backbone network after operationally using the finally deployed tool for half a year. We think that this first hand information can be of great interest to both professionals and researchers working on network security and can also guide future research towards more practical problems faced by network operators. © 2012 Elsevier Ltd.

Global research collaborations today require reliable and secure dedicated network connections to facilitate data communications between collaborating partners. To deal with the deluge of data, dedicated connections are needed to transport data in a highly efficient manner. Managing such links, which often cross multiple administrative domains with heterogeneous infrastructure, poses many compelling research challenges, one of which is interdomain network monitoring. In this article, a multidomain circuit monitoring system, CMon, is introduced. Using some services of GÉANT perfSONAR MDM, CMon is able to provide end-to-end circuit monitoring services with great flexibility, extensibility, and vendor independence, regardless of the underlying circuit provisioning systems. The architecture of CMon, by using measurement federations, can adapt to either changes in the circuit provisioning system or expansion of network size. © 2014 IEEE.

The Large Hadron Collider (LHC) is currently running at CERN in Geneva, Switzerland. Physicists are using LHC to recreate the conditions just after the Big Bang, by colliding two beams of particles and heavy ions head-on at very high energy. The project is generating more than 15 TB of raw data per year, plus 10 TB of "event summary data". This data is sent out from CERN to eleven Tier 1 research centres in Europe, Asia, and North America using a multi-gigabits Optical Private Network (OPN), the LHCOPN. Tier 1 sites are then connected to 100+ academic and research institutions in the world (the Tier 2s) through a Multipoint to Multipoint network, the LHC Open Network Environment (LHCONE). Network monitoring on such complex network architecture to ensure robust and reliable operation is of crucial importance. The chosen approach for monitoring the OPN and ONE is based on the perfSONAR framework, which is designed for multi-domain monitoring environments. perfSONAR (www.perfsonar.net) is an infrastructure for performance monitoring data exchange between networks, making it easier to solve performance problems occurring between network measurement points interconnected through several network domains.
