The Tommie Science Network: A High-Speed Research Network and ScienceDMZ

NSF Grant

Did you know that St. Thomas has received a grant of nearly $400,00 from the National Science Foundation to build a high-speed research network? The grant money will fund a science network that will connect researchers to a ScienceDMZ, which allows for extremely fast transfers within the network and to other institutions via Internet2. Initial speeds of up to 100Gb are planned, opening doors to significantly larger research datasets and real-time collaborations than are possible on a conventional network.

The Tommie Science Network

A research network achieves these speeds through a variety of mechanisms, starting with a network switch that can handle the speed. This is the single most expensive item in the project, coming in over $100,000 for a switch that will be dedicated to the science network. Typically, a science network is outside of the enterprise firewall as well, because a modern firewall inspects each packet (unit of information) that passes through it, causing unacceptable slowdowns to research traffic. To get around this, Access Control Lists on the research network switch have typically been employed, which allow authorized traffic to bypass the firewall. A modern method uses the ability of an enterprise firewall to detect the nature of incoming traffic and route it through the science network if authorized. This method maintains the speeds required for research computing but offers enhanced security and efficiency because the pipe is only open during transmission, rather than sitting idle waiting for traffic. Specialized software components include Globus, a high-speed file transfer and management system, and PerfSonar, a tool for monitoring and maintaining research network speeds. Finally, a DTN, or Data Transfer Node sits in the ScienceDMZ, consisting of a very fast computer with very large, very fast SSD storage drives. Research clusters, GPU machines and other research technology can also be placed in the ScienceDMZ for maximum efficiency. The University of Minnesota is our partner in this effort and will help us design the network as part of the grant. This is a huge benefit for St. Thomas as UMN has significant experience in this area and has direct access to the Northern Lights GigaPOP (Gigabit Point of Presence), where we hook up to Internet2!

NSF CC* PI Conference

One condition of the grant is that the PI (Principal Investigator) attend the NSF CC* (National Science Foundation Cyberinfrastructure and Cybersecurity) conference in each of the grant years (this is a 2-year project). In September, Ed, Will and I attended this conference at the University of Maryland and gave a brief presentation on our grant. Writing the grant was a significant effort (especially since we had to do it twice- our first attempt was not awarded), which produced a 70+ page document highlighting the amazing science that is going on at St. Thomas. Many in the crowd empathized with our story and several shared similar experiences with us afterward. The conference in general was excellent. It was tight-knit group consisting of government funders, researchers, technologists and research network consortium principles. We learned a lot about how NSF funding works, pitfalls to avoid in network design and general best practices for running and maintaining a research network. The conference was in Maryland, which was extremely hot and humid during our stay. The University of Maryland hosted the conference on their lovely Georgian campus (apparently the only two design choices in the DC area are Georgian or Brutalist):










UMD has an area similar to Dinkytown nearby called College Park. Here are some of us with colleagues from the University of Minnesota and the University of Iowa (both of whom received similar grants) at MilkBoy Arthouse in College Park:

The Road Ahead

Now the fun begins- The grant period runs for two years, with a one-year extension possible. The first year will be dedicated to designing the network. Meetings have begun with UMN research networking staff as well as St. Thomas researchers as we consider the technical, organizational and support structures that will best serve our research community. When the network goes live 2-3 years from now, we will enter a new era of research capability at St. Thomas. This network will allow us to collaborate with other universities and science centers around the world at peer speeds, allow researchers from other institutions to logon to our resources with their own credentials, and provide seamless, high-speed access internally and externally to extremely large data sets that have been impossible to access at our current network speeds. This will in turn allow us to attract more high-quality researchers (to join our already exemplary cohort!) by offering them resources with capabilities normally found at much larger institutions.


We have taken the first step on the path to a significant upgrade to the university’s research computing capability. When complete, we will have access to Internet speeds that provide parity with the largest research universities and institutions in the world, along with a shared, secure identity space via InCommon that securely offers seamless, high-speed access to resources at any participating institution to any authorized researcher. From these seeds will grow a brand-new branch of the St. Thomas tree and resonate throughout the institution (and the world) for years to come.

Upcoming Technologies

Virtually There: The Current State of Virtual and Augmented Reality

A year has passed since Virtual Reality, or VR, made a big splash with the introduction of Oculus Rift and HTC Vive at the high end, Sony PS4 in the middle and Galaxy Gear, Google Cardboard and Google Daydream offering the simplest (yet still compelling) experience. This year each major player will release a second generation VR device, and there are some new companies and technologies joining the mix.

While Virtual Reality blew away everyone who experienced it, VR did not see tremendous mainstream adoption. The systems were simply too complex and expensive to interest casual users. Sales figures bore this out: PS4 VR sold more than Oculus and Vive combined, due to the built in user base, lower price, and simplified setup. Even so, most people have probably experienced VR through Google Cardboard devices, as they are an extremely low-cost entry into VR (assuming you already have the expensive phone required to operate it!)


So what’s happening in the Year 2 VR? Already out is the HTC Vive Pro, which doubles the resolution of the original Vive, along with the Wireless Adapter for the Vive, so there go the tethers! Another forthcoming Vive technology is the Vive Anchor. The Anchor will precisely place your entire body in the virtual world for more accurate tracking.


The next generation of PC-based Oculus Rift has been cancelled in favor of the Oculus Quest, which has not yet been released yet (more about that later). In the meantime, Oculus has released the Oculus Go, which is a lower-powered version of the Quest that uses a single controller. The Go is a standalone headset similar to Galaxy Gear or Google Daydream, with the exception that no phone is required because the technology is built in to the headset. The Go, at $200 for the 32 GB version, is a major step-up from a cell phone setup. The resolution is better, the built-in software is excellent (Virtual Telepresence, anyone?) and the comfort and operation are significantly improved. STELAR has two Oculus Go’s in the showcase to try out. During testing, I played a game of chess with my daughter via Oculus Rooms. I was in my office and she was at home. The experience was seamless and immersive. You both appear in a virtual game room and can see each other’s avatars, with good lip sync. Conversation is very natural. One of the best features of the Go is the Spatial Sound. You can easily locate sounds in three dimensions when using the headset, which significantly heightens the sense of reality!


Another new VR technology we have in STELAR is called ClassVR. This is a system of VR goggles that can be controlled from a central location, e.g. the teacher, who can allow students to explore on their own or deliver a specified lesson plan to all goggles at once. The goggles come in a road-ready case for easy transport. Another part of ClassVR is their authoring system, which is used to make content for VR lessons. The authoring system is a series of pre-created VR elements, lessons and demonstrations that can be assembled by a teacher into a custom lesson on many different topics, from anatomy to English to space exploration. This system is intended to go out into the field and be practically used in actual classes, so if you are interested in exploring VR lesson creation and delivery, let us know!

Augmented Reality

The big reality story in 2019 is AR- Augmented Reality. Unlike VR, which completely immerses the user and cuts them off from the outside world, AR combines computer generated imagery with the real world, allowing you to see things that appear to exist in reality but don’t! As an example, imagine you are building a new skyscraper. With AR technology, you could create a virtual model of the proposed building, go onsite and see what the building would look like on the actual lot before it was built! You could even go inside the virtual building and walk the layout.

Magic Leap

One of the most anticipated AR devices came out in late 2018, called Magic Leap. We have a Magic Leap in the STELAR Showcase. Early users have had strong reactions, both negative and positive. Digital artifacts seen through the Leap appear to interact with objects in the room- virtual objects falling on tables, breaking apart and rolling to the floor. Life-size virtual avatars that appear to be standing on the ground in front of you. Portals that open on the walls and allow you to gaze into infinity. Interactive bioluminescence! If you’ve been wowed before by VR, come be wowed again by AR!


Projected AR. This brand new product (releasing in November, first wave sold out, ours is coming in April!) couples with a projector to create pixel-accurate AR! It includes a GUI design interface for code-free AR creation. Examples I saw included uncarved pumpkins that were made to look carved with burning candles inside, white skeletons (it was Halloween) on which animated, Day of the Dead-style tattoos would appear, and white parasols that appeared to have rotating, multi-colored patterns. This technology seems ideally suited to educational uses- AR annotation of real objects, sculpture projected onto blank forms, even AR-enabled Tommie welcoming you to campus!


SparkAR Studio

Another AR technology that’s been around for awhile is Facebook’s AR Studio, recently renamed SparkAR Studio. They’ve also removed the coding requirements to make it entirely GUI-based. This software is used to create AR experiences viewed through Android or iOS phones. You’ve probably seen it being used to add dog or cat ears to people, face-tracking scary clown makeup, and many other digital creations that map onto your face or other objects. This is one of the easiest entry points into AR creation, and is potentially one of the most lucrative as it has direct access to millions of Facebook and Instagram users. SparkAR Studio is free to download. Mac only at this time, but a PC version is promised this year.

And More!

As mentioned previously Oculus just announced the spring release of the Oculus Quest, a stand-alone headset with room tracking and hand controllers. This is an exciting development that promises to bring some portion of the power of a connected headset to a completely portable unit!


While VR wasn’t a big commercial hit initially, the technology clearly opens up new territory in a variety of areas including art, scientific visualization, training and education. When the technology is able to deliver a comfortable, cost-effective solution, usage will potentially skyrocket. Think of the first cell phones, (called “car phones” at the time): They cost thousands of dollars (the equivalent of $16,000 of today’s dollars!), were extremely limited in their functionality, of little practical value, and literally had a battery the size of a suitcase! Virtual Reality is currently in the “suitcase cellphone” era, but an era where VR/AR services are delivered in real time, at photorealistic resolution without tethers or bulky goggles is easily imaginable.


STELAR’s goal in year two is to move VR/AR beyond the showcase, and begin exploring pedagogically significant uses of VR/AR. Practically, this means partnering with professors to build VR/AR into the lesson. This has been happening already, with Dr. Alison Underthun-Meilahn’s Wartime Literature class using complementary virtual experiences to supplement their reading, and Art History’s use of 360 cameras- another easy-to-use VR creation tool- to capture not just the art their students visit around the world, but the cultural and physical context in which it exists, providing a glimpse into that experience for those who didn’t physically make the trip. VR/AR can be used in many different ways at many different levels of technical execution. If you have an idea for using VR in teaching, STELAR can help you figure out a way to make it a reality that’s more than just virtual!















How do you use your “earth station”?

We can instantly choose one of millions of videos to play on-demand with just a couple of taps on a magic piece of glass called a “phone”…and that’s really, really different than the way content was once consumed.

Thirty-five years ago, HOME Magazine ran a story on what they said were called “earth stations.”

"Will your neighbor's house look like a space station? Don't laugh. It's happening in a number of places around the country. Dish antennas -- some of them 12 feed across -- are sprouting like dandelions, many of them in front yards. You can imagine how neighboring property owners react. Called earth stations, the gadgets zero in on TV satellites, pick up the signals, and feed them into the homeowner's television set. As many as 80 different channels can be received, including many foreign-language stations. The antennas, which sell in the $3,000 to $10,000 price range, have been bought by the thousands in urban areas as well as paces not yet reached by commercial or cable TV. The earth stations can bring in any and every type of entertainment from ballet to X movies, any time of day or night. So if you thought the job of controlling your children's viewing habits was tough before...

The $3,000 price in 1982 would be more than $7,000 today.  Remember, this was an era when “time-shifting” was impossible unless you were one of the few to own a VCR, and “on-demand” was inconceivable.  Eighty channels has grown by a factor of about one million.  Viewing “many foreign-language stations” is nothing compared to having actual content from peers and producers sent to you across the planet.

And the notion of “controlling” viewing habits (of children, or of ourselves)?  Nobody could have imagined…

So at one time, people were willing to spend months’ worth of wages to fill their yard with a giant metal dish… to choose from among 80 channels.  Was that for education?  Or for entertainment?  Now that we have the world at our fingertips (literally), do we show the same level of dedication to learning from others across the globe?  Entertainment has changed in 35 years… but not that much.  We still go to movie theaters.  We still go to live theaters and concerts.  We still sit in our living rooms in front of large screens (now larger and flatter and clearer, but still remarkably like the televisions of the 1980s) viewing movies, one-hour dramas, sports and sit-coms.  Did swiping through Facebook (or Instagram or Tinder) change the nature of how we engage with the world?
