perfSONAR-PS Status Services

There are two types of status services: measurement and circuit.

The Status Measurement Archive provides a way for an administrator to provide layer2 link status information to remote clients. This information can be obtained via a polling service that can use SNMP, or scripts to collect the
link status information, and stores it into a SQL database. The technique used to store the information helps minimize the storage requirements of rarely changing links.

The Circuit Status Service is called E2EMon, a commonly used service that provides a webpage containing status information about inter-domain circuits. In order to produce the webpage, the service requests the complete state of each domain in the circuits it has an interest in and then correlates this information to produce end-to-end statistics. This Circuit Status service uses the Status Measurement Archive and can use the Topology Service to provide the complete domain status required by the E2EMon service.
