Space Link Extension - Service Management - CCSDS

DRAFT RECOMMENDED STANDARD FOR SPACE LINK EXTENSION SERVICE MANAGEMENT
ASLEPD-3
ASLEPD-4
Each [R|F]SpaceLinkAvailableStates data set:
a) shall contain zero or more [R|F]SpaceLinkChangeEvent data sets;
[syntactic validation]
b) shall contain zero or more [R|F]FSpaceLinkDataTransportState data sets;
[syntactic validation]
c) shall have a stateEndTime parameter value which is either null or greater than the
corresponding stateStartTime;
[service management validation]
d) shall have a null stateEndTimeWindow parameter value if the corresponding
stateEndTime parameter value is also null;
[service management validation]
e) shall have an availableStateInstanceNo parameter value which is unique within
the [R|F]SpaceLinkEvents;
f) shall have an availableStateInstanceNo parameter value which is larger than all other
availableStateInstanceNo parameters corresponding to earlier
[R|F]SpaceLinkAvailableStates data sets;
[service management validation]
g) shall constrain all stateStartTime parameters such that application of the
stateStartTimeWindowLead and stateStartTimeWindowLag parameters do
not violate minEventTemporalSpacing;
[service management validation]
h) shall order all contained [R|F]SpaceLinkChangeEvent data sets chronologically in
ascending order by eventTime;
[service management validation]
i) shall order all contained [R|F]SpaceLinkChangeEvent data sets in ascending order
by eventInstanceNo;
[service management validation]
j) shall order all contained [R|F]SpaceLinkDataTransportState data sets
chronologically in ascending order by stateStartTime;
[service management validation]
k) shall order all contained [R|F]SpaceLinkDataTransportState data sets in
ascending order by availableStateInstanceNo.
[service management validation]
Each [R|F]SpaceLinkChangeEvent data set:
a) shall have a non-null EIRP parameter value which is different than the EIRP parameter
value of the previous [R|F]SpaceLinkChangeEvent associated with the
parent [R|F]SpaceLinkAvailableStates, or if no previous
[R|F]SpaceLinkChangeEvent exists, the EIRP parameter value shall be different
than the EIRP associated with the carrier profile referenced by the
carrierProfileRef of the parent [R|F]SpaceLinkEvents;
[service management validation]
NOTE – FSpaceLinkChangeEvent might not be necessary but is left in specifications for
potential use.
b) shall constrain the eventTime parameter such that application of the
eventTimeWindowLead and eventStartTimeWindowLag parameters do not
violate minEventTemporalSpacing;
[service management validation]
c) shall have an eventInstanceNo parameter value which is unique within the
[R|F]SpaceLinkAvailableStates;
d) shall have an eventInstanceNo parameter value which is larger than all other
eventInstanceNo parameters corresponding to earlier
[R|F]SpaceLinkChangeEvent.
[service management validation]
