Space Link Extension - Service Management - CCSDS

DRAFT RECOMMENDED STANDARD FOR SPACE LINK EXTENSION SERVICE MANAGEMENT
Validate SLE-SM Exception Response activity subgroup of the Document Exchange
Protocol activity group specified in 3.3. The Invoker attempts to correlate the contents of
each syntactically correct UnrecognizedMessageSetResponse and
InvalidMessageResponse with SLE-SM operation Invocations that have been
sent by the Invoker. If the UnrecognizedMessageSetResponse or
InvalidMessageResponse can be correlated to one or more Invocations, the
Invoker terminates the correlated operation(s), and completes the procedure. The Invoker
may perform local functions specific to an unknown or invalid Invocation as part of
completing the operation procedure (e.g., update local databases to reflect failure of the
operation, contact the Performer to troubleshoot the failure).
Upon receipt of the SleSmMessageSet containing the SuccessfulReturn message,
the Invoker performs message set validation as specified for the Receive and Validate SLE-
SM Message Set activity subgroup of the Document Exchange Protocol activity group in 3.3.
If the SleSmMessageSet passes message set validation, the Invoker performs service
management validation on the SuccessfulReturn. The details of service management
validation are specific to each operation, and are specified in the associated Invoker and
Performer requirements for each operation. If the SuccessfulReturn passes service
management validation, the Invoker completes the operation procedure. The Invoker may
perform local functions specific to a successful operation as part of completing the operation
procedure (e.g., updating local databases to reflect success of the operation). If the message
set fails syntactic or authorization validation, the Invoker generates and transmits an
exception response containing an UnrecognizedMessageSetResponse to the
Performer’s exception response port, as specified in 3.3. If the SuccessfulReturn
message fails service management validation, the message is deemed invalid and the Invoker
is not required to interpret or act upon the message any further.
Upon receipt of the SleSmMessageSet containing the FailedReturn* message, the
Invoker performs message set validation as specified for the Receive and Validate SLE-SM
Message Set activity subgroup of the Document Exchange Protocol activity group in 3.3. If
the SleSmMessageSet passes message set validation, the Invoker performs service
management validation on the FailedReturn*. The details of service management
validation are specific to each operation, and are specified in the associated Invoker and
Performer requirements for each operation. If the FailedReturn* passes service
management validation, the Invoker completes the operation procedure. The Invoker may
perform local functions specific to a failed operation as part of completing the operation
procedure (e.g., update local databases to reflect failure of the operation, contact the
Performer to troubleshoot the failure). If the SleSmMessageSet fails syntactic or
authorization validation, the Invoker generates and transmits an exception response
containing an UnrecognizedMessageSetResponse to the Performer’s exception
response port, as specified in 3.3. If the FailedReturn* message fails service
management validation, the message is deemed invalid and the Invoker is not required to
interpret or act upon the message any further.
