The Science DMZ architecture includes a test and measurement hosts based on perfSONAR. This host helps with fault diagnosis on the Science DMZ, and with end-to-end testing with collaborating sites if they have perfSONAR installed. The perfSONAR host can run continuous checks for latency changes and packet loss using OWAMP, as well as periodic throughput tests to remote locations using BWCTL. If a problem arises that requires a network engineer to troubleshoot the routing and switching infrastructure, the tools necessary to work the problem are already deployed - they need not be installed before troubleshooting can begin.
