GSC Sentinel-2 PDGS SRD Issue 1 Revision 2 (draft) - 25.07.2010 GMES-GSEG-EOPG-RD-09-0028 page 24 of 204 Maintainability Service Downtime Stop-clock Periods MTTR Round Trip Delay Outage Lead Time Mission Lifetime PDGS Operational Lifetime The ease with which a product can be maintained in order to: correct defects (corrective maintenance) cope with a changed environment (adaptive maintenance) meet new requirements (perfective/improving maintenance) make future maintenance easier (preventive maintenance) Service Downtime = Downtime - Stop-clock Periods Stop-clock Periods are scheduled downtimes and downtimes that are beyond the direct control of the Operational Support, as the resolution of incidents in the service scope of the Internet Network Providers. Maximum Time To Repair. The MTTR starts when an outage occurs and is to be concluded when the service is restored. Round trip delay, also called propagation delay. Round trip delay is the amount of time it takes for a packet for being (de-) encapsulated, routed/switched and transmitted to the other end and back; i.e. it is propagation delay + transmission delay + processing delay. This is measured from the outside interface of the Contractor’s WAN border device on one site to the outside interface of the Contractor’s WAN border device on the other site. An outage is an incident during which the warranted service is not provided. Lead-time is the time allowed to the service operator to recover from the outage condition. After this lead-time, the outage is taken into account in the credit scheme calculations. The Sentinel-2 mission lifetime covers a minimum of 13.5 years with active space-segment operations. The PDGS operational lifetime covers the Mission Lifetime plus 25 additional years to support Long Term Data Preservation (LTDP) activities. LTDP activities are the ones related to the maintenance and the exploitation of the Sentinel-2 data archives including data preservation, processing, cataloguing, data access, etc activities performed during and sustained beyond the satellite operational periods.
