perfSONAR-BUOY
The perfSONAR-BUOY Measurement Archive service (pSB MA) exposes active measurement data, making the results available through perfSONAR web services interfaces. All performance tests are performed via the BWCTL tool (throughput measurements) and currently consist of regularly-scheduled Iperf tests to a configurable list of source and destination hosts.
Data collected through the BWCTL interaction is stored in a MySQL database. Active measurements between known hosts are particularly valuable when assuring connectivity, availability, and quality of the network. perfSONAR-BUOY allows for the easy configuration of a "mesh" of tests to hosts equipped with BWCTL. Based on a configurable schedule, the tests will be conducted autonomously and stored for consumption via the perfSONAR-BUOY interface as well as presentation through included web scripts. Using the same XML protocols as the the other perfSONAR services, perfSONAR-BUOY provides uncomplicated access methods to retrieve the data in an unambiguous manner, thus eliminating the mystery associated with the backend storage. Closely coupled with development on BWCTL, perfSONAR-BUOY will soon offer data originating from sources besides Iperf such as OWAMP (latency measurements), Thrulay, and nuttcp.
