Monitoring at Terabit speeds

The chart was generated from industry standard sFlow telemetry from the switches and routers comprising The International Conference for High Performance Computing, Networking, Storage and Analysis (SC16) network. The chart shows a number of conference participants pushing the network to see how much data they can transfer, peaking at a combined bandwidth of 3 Terabits/second over a minute just before noon and sustaining over 2.5 Terabits/second for over an hour. The traffic is broken out by MAC vendors code: routed traffic can be identified by router vendor (Juniper, Brocade, etc.) and layer 2 transfers (RDMA over Converged Ethernet) are identified by host adapter vendor codes (Mellanox, Hewlett-Packard Enterprise, etc.).

From the SCinet web page, "The Fastest Network Connecting the Fastest Computers: SC16 will host the most powerful and advanced networks in the world – SCinet. Created each year for the conference, SCinet brings to life a very high-capacity network that supports the revolutionary applications and experiments that are a hallmark of the SC conference."

SC16 live real-time weathermaps provides additional demonstrations of high performance network monitoring.
