perfSONAR MDM Service Configuration
Recommendations
The purpose of this document is to ensure that the proper elements of the monitoring infrastructure
and their configurations are in place to provide consistent perfSONAR MDM monitoring service
support and delivery to the GÉANT Service Area users by participating domains.
Configuration recommendations
The purpose of this section is to ensure that the proper elements of the monitoring infrastructure
and their configurations are in place to provide consistent GN3 perfSONAR MDM monitoring service.

UDP Tests
Measurement Storage
This section describes recommendations for measurement storage.
On-demand Tests Measurement Storage
No measurement storage is required in this use case.
Scheduled Tests Measurement Storage
Store a minimum of 12 months of non-summarised format for both One-Way Delay and Achievable
Bandwidth Tests.
Scheduled
Inter-domain results of measurements between a domain and its upper tier must
be stored and exposed by the appropriate Measurement Archive of the upper tier
domain.
Inter-domain results of measurements between two adjacent domains of the
same tier must be stored and exposed by the appropriate Measurement Archive
of the source domain of the test.
Intra-domain
Intra-domain results must be stored by the domain and exposed via its own
Measurement Archive.
For more information about deployment scenarios read “perfSONAR MDM Service Architecture and
Scenarios” document.
