SC22 SCinet network monitoring

The data shown in the chart was gathered from The International Conference for High Performance Computing, Networking, Storage, and Analysis (SC22) being held this week in Dallas. The conference network, SCinet, is described as the fastest and most powerful network on Earth, connecting the SC community to the world. The chart provides an up to the second view of overall SCinet traffic, the lower chart showing total traffic hitting a sustained 8Tbps.

The poster shows the topology of the SCinet network. Monitoring flow data from 5,852 switch/router ports with 162Tbps total bandwith with sub-second latency is required to construct the charts.

The chart was generated using industry standard streaming sFlow telemetry from switches and routers in the SCinet network. An instance of the sFlow-RT real-time analytics engine computes the flow metrics shown in the charts.

Most of the load was due to large 400Gbit/s, 200Gbit/s and 100Gbit/s flows that were part of the Network Research Exhibition. The chart above shows that 10 large flows are responsible for 1.5Tbps of traffic.

Scientific network tags (scitags) describes how IPv6 flowlabels allow network flow analytics to identify network traffic associated with bulk scientific data transfers.

RDMA network visibility shows how bulk data transfers using Remote Direct Memory Access (RDMA).
