100G workshop targets 'last-mile' outreach to application end-users
Workshop panels and presentations focused on the myriad ways in which 100-Gigabit networks will spur technology innovation in the decades to come.
Sponsored by the California Institute of Telecommunications and Information Technology (Calit2), the Energy Sciences Network (ESnet) and the Corporation for Education Network Initiatives in California (CENIC), the recent 100G and Beyond Workshop was held on February 26 in Calit2’s Atkinson Hall, on the campus of UC San Diego.
The one-day workshop was held in conjunction with the 12th Annual ON*VECTOR International Photonics Workshop. The goal of the workshop was to examine 100-Gigabit networking and the ways in which it will impact areas as diverse as data-intensive science, health care, media arts applications, smart manufacturing, and more.

Workshop panels and presentations focused on the myriad ways in which 100-Gigabit networks will spur technology innovation in the decades to come. Also covered were the campus and lab strategies that could enable researchers and the facilities in which they operate to take full advantage of 100G for research and education networking, innovation on the network itself, and in regional, national, and international testbeds.
“100-Gigabit networking is new standard for data-intensive research and education, and workshops like these are necessary to understand the way ahead, not only in terms of network design, but also to make sure that applications, facilities, and researchers themselves are prepared to take as much advantage of ultra-high-performance networks as possible,” commented CENIC's president and CEO, Louis Fox, at the workshop's opening.
Calit2 Director Larry Smarr concurred, citing PRISM@UCSD, a campus network project enabled by a recent National Science Foundation grant to UCSD’s Phil Papadopoulos.
“We’ve brought together a wide range of data intensive application users with network specialists to create a unique user-driven high-bandwidth campus cyberinfrastructure,” Smarr said. “This 'last-mile' outreach to the application end-users must be done worldwide if the global research community is to see all the possible benefits of 100G networking.”

According to a press release, PRISM will create optical “Big Data Freeways,” with speeds between 10 and 120 Gb/s, between data-intensive users, scientific instruments, clusters, and Calit2 and the San Diego Supercomputer Center, where it will interconnect to a CENIC 100G connection. Further, PRISM will provide an “easy-to-replicate” prototype of what can and must be done to ensure that the benefits of wide area 100G networking reach all the way into individual users and their labs.
At the workshop, ESnet Director Greg Bell also spoke of the necessity for community-building when observing the growth of traffic on the Energy Science Network, which provides the high-bandwidth connections that link scientists at national laboratories, universities, and other research institutions.
“Traffic on our network has historically grown by ten times every four years, and doubles every 18 months, and 80% of the traffic on ESnet goes beyond it to other networks," said Bell. "There is an extremely tight coupling between ESnet and other national and regional networks, and the communities they serve.”
After Bell, Fox, and Smarr welcomed attendees, the event began with a treatment of the scientific, medical, and media arts applications that will benefit from 100-Gigabit networking, chaired by Smarr.
This session ran the gamut of applications, from ocean and climate research to high-resolution microscopy, protein structure databases, and digital cinema. During a spirited question and answer session, Smarr reminded the attendees that, “There are twice as many 100G applications, just at UCSD, as you’ve heard about today on the panel.”
UCSD’s Dan Cayan then addressed the complexity of climate research as a big-data science, and Vicky Rowley of the National Center for Microscopy and Imaging Research (NCMIR) similarly described high-resolution microscopy.

The study of protein structure was the focus of the next two talks by UCSD’s Andreas Prlic of the Protein Data Bank and Ian Kaufman representing the Center for Computational Mass Spectrometry, while the Ocean Observing Initiative Cyberinfrastructure’s Matthew Arrott focused on ocean observing as a big-data science with strong dependency on high-bandwidth networking.
Laurin Herr of CineGrid concluded the panel’s presentations by describing the unique and very pressing dependency of digital cinema on advanced networks, given that after one hundred years, analog film is widely recognized in the media industry as dead, and the transition to purely digital is here.
The next session, chaired by Lawrence Berkeley Laboratories’ Brent Draney, examined campus and lab strategies for designing local network build-outs that can make best use of ultra-high-performance networking. SDSC/Calit2’s Phil Papadopoulos described the PRISM@UCSD technology in detail, while Pete Siegel spoke of UC Davis’s plans, taking special care to mention the necessity of involving the entire community from network specialists to faculty and staff to undergraduates.
Also, Christopher Paolini of San Diego State University described the design of that campus’s Science DMZ, and Brent Draney of NERSC addressed implementing security on tomorrow’s high-bandwidth networks, observing that, “security controls should enable scientific productivity, not impede it.”
The third area of focus was smart manufacturing, chaired by UCLA’s Jim Davis. Davis, together with Mark Goodstein of the Center for Smart Manufacturing Innovation (CSMI) and Caltech’s Si-ping Han, described the complex landscape of smart manufacturing to workshop attendees, from the community-building that must inform the design of any network that enables smart manufacturing, to making sure that manufacturers can take best advantage of nanoscale science during design, modeling, and assembly, and proposing potential business models for organizations that seek to promote and advocate for smart manufacturing.
Software-Defined Networking (SDN) emerged as a major topic of subsequent panels on network innovation and testbeds. ESnet’s Inder Monga chaired a panel on 100-Gigabit network innovations including software-defined networking enabling the network to become a programmable instrument.
The San Diego Supercomputer Center’s Mike Norman, Lawrence Berkeley National Laboratories’ Zarija Lukic, Caltech’s Harvey Newman, Stanford’s Johan van Reijendam, and Clemson University’s KC Wang all spoke of the importance of dynamic circuits enabled by SDN to take full advantage of what 100G networking can provide, especially for the data-intensive sciences.
USC’s John Silvester chaired the day’s final panel on scientific workflows and testbeds. Ewa Deelman, also of USC, discussed how scientific workflow and network design can be used to inform one another to optimize both science and network. CENIC’s Brian Court described the California OpenFlow Testbed Network (COTN), created by CENIC to enable network researchers in California to carry out OpenFlow and SDN-related research.
Brian Tierney of ESnet described that network’s own tiered testbed, with one tier for 100G research, one OpenFlow-enabled tier, and another dark-fiber tier. UCSD’s Dallas Thornton and the UC Office of the President’s Paul Weiss concluded the panel programming with discussions of cloud services implementations at SDSC and the importance of efficiency in network engineering.
Bridging the gap between campus innovations to California and national testbeds was the topic for the concluding discussion, led by Bell, Fox, and Smarr. Once again, the panelists and attendees quickly focused on the vital importance of reaching out to a wide range of application users to ensure that any ultra-high-performance network is the end-product of collaboration between network specialists and the widest possible breadth of app users starting from the earliest design stages.
“Without the application drivers,” Smarr observed, “you end up with empty networks.” However, the workshop demonstrated that many data-intensive applications are ready and able to make the jump to 100G optical flows, opening entirely new vistas for scientific discovery.
