What is perfSONAR?
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.

Technical Overview
perfSONAR is a services-oriented architecture -- the set of elementary functions have been isolated and can be provided by different entities called services. All those services communicate with each other using well-defined protocols. Below are links to an overview of the perfSONAR:
