perfSONAR is an infrastructure for network performance monitoring, making it easier to solve end-to-end performance problems on paths crossing several networks. It contains a set of services delivering performance measurements in a federated environment. These services act as an intermediate layer, between the performance measurement tools and the diagnostic or visualization applications. This layer is aimed at making and exchanging performance measurements between networks, using well-defined protocols.
AMPATH has a perfSONAR node installed in the NAP of Americas, in Miami, Fl., that it is connected to the perfSONAR Global Community.
If you are a perfSONAR member that is connected to the Internet, you can access the AMPATH perfSONAR node at the following website: http://perfsonar.ampath.net/toolkit/
