ESnet Connections Peak at 270 Gbps Flow In, Out of SC14 Conference

The booths have been dismantled, the routers and switchers shipped back home and the SC14 conference in New Orleans officially ended Nov. 21, but many attendees are still reflecting on important connections made during the annual gathering of the high performance computing and networking community.

Among those helping make the right connections were ESnet staff, who used ESnet’s infrastructure to bring a combined network capacity of 400 gigabits-per-second (Gbps) in the Ernest Morial Convention Center. Those links accounted for one third of SC14’s total 1.22 Tbps connectivity, provided by SCinet, the conference’s network infrastructure designed and built by volunteers. The network links were used for a number of demonstrations between booths on the exhibition floor and sites around the world.

A quick review of the ESnet traffic patterns at https://my.es.net/demos/sc14#/summary shows that traffic apparently peaked at 12:15 p.m. Thursday, Nov. 20, with 79.2 Gbps of inbound data and 190 Gbps flowing out.

Among the largest single users of ESnet’s bandwidth was a demo by the Naval Research Laboratory, which used ESnet’s 100 Gbps testbed to conduct a 100 Gbps remote I/O demonstration at SC14.

NRL and Collaborators Conduct 100 Gigabit/Second Remote I/O Demonstration

The Naval Research Laboratory (NRL), in collaboration with the DOE’s Energy Sciences Network (ESnet), the International Center for Advanced Internet Research (iCAIR) at Northwestern University, the Center for Data Intensive Science (CDIS) at the University of Chicago, the Open Cloud Consortium (OCC) and significant industry support, have conducted a 100 gigabits per second (100G) remote I/O demonstration at the SC14 supercomputing conference in New Orleans, LA.

The remote I/O demonstration illustrates a pipelined distributed processing framework and software defined networking (SDN) between distant operating locations. The demonstration shows the capability to dynamically deploy a production quality 4K Ultra-High Definition Television (UHDTV) video workflow across a nationally distributed set of storage and computing resources that is relevant to emerging Department of Defense data processing challenges.

ESnet’s Brian Tierney Discusses Network Performance in HPCwire Podcast

In an interview with HPCwire editor Nicole Hemsoth, Brian Tierney, leader of the ESnet Advanced Network Technologies Group at  ESnet’s 100G Network Testbed Project, discusses network performance issues, including the 1,000th deployment of the perfSONAR network measurement software.

In the 20-minute  interview, Brian talks about how he originally got interested in network performance, the current state of ESnet and how institutions can assess and improve the performance of their network connections, such as referring to the fasterdata.es.net knowledge base. He also describes how Science DMZs can safely transfer massive datasets around firewalls and touches on the potential of Software Defined Networking.
