 +[[dido:03-dido-te:99-annexes:annex-c-requirements:03-functional-requirements:03-02-node-requirements:start|Go to Node Requirements]]
 +
 +===== Statement =====
 +
 +The [[dido:99_annexes:annex-b-terms-and-definitions:d:dido-te|DIDO-TE]] SHALL control the execution of each [[dido:99_annexes:annex-b-terms-and-definitions:n:node|Node]] participating in [[dido:99_annexes:annex-b-terms-and-definitions:t:test_execution|Test Execution]].
 +
 +===== Derived From =====
 +
 +  * [[dido:03-dido-te:99-annexes:annex-b-references:dte-005|[DTE5] DIDO-TE Requirements Register]], source requirement identifier and obligation to be assigned
 +  * [[dido:03-dido-te:99-annexes:annex-b-references:dte-006|[DTE6] Structured Information Processing Reference Architecture (SIP-RA)]]
 +  * [[dido:03-dido-te:99-annexes:annex-b-references:dte-007|[DTE7] Federated Data Interpretation Systems Reference Architecture (FDIS-RA)]]
 +
 +===== Rationale =====
 +
 +Node execution governs the operation of a Node while it performs its assigned role in Test Execution.
 +
 +The applicable [[dido:99_annexes:annex-b-terms-and-definitions:n:node_definition|Node Definition]], [[dido:99_annexes:annex-b-terms-and-definitions:n:node_implementation|Node Implementation]], [[dido:99_annexes:annex-b-terms-and-definitions:n:node_configuration|Node Configuration]], and [[dido:99_annexes:annex-b-terms-and-definitions:t:test_definition|Test Definition]] determine the authorized Node behavior, execution parameters, [[dido:99_annexes:annex-b-terms-and-definitions:t:test_input|Test Inputs]], Node Bindings, resource constraints, operating conditions, and expected outputs.
 +
 +Node lifecycle control establishes and maintains the Node state required for execution. Node execution control governs the Node activity performed within that state. A ready Node does not participate in Test Execution until the DIDO-TE authorizes and initiates its execution.
 +
 +Controlled Node execution coordinates Node activity with other Nodes and [[dido:99_annexes:annex-b-terms-and-definitions:t:test_resource|Test Resources]], supplies authorized Test Inputs, observes behavior and outputs, detects deviations, handles execution exceptions, and records the resulting activity.
 +
 +Uncontrolled, unauthorized, incorrectly sequenced, or unobservable Node execution may produce invalid [[dido:99_annexes:annex-b-terms-and-definitions:t:test_result|Test Results]], affect other Nodes, compromise Test Environment isolation, or prevent reconstruction of Test Execution.
 +
 +===== Applies To =====
 +
 +  * [[dido:99_annexes:annex-b-terms-and-definitions:d:dido-te|DIDO-TE]]
 +  * [[dido:99_annexes:annex-b-terms-and-definitions:n:node|Node]]

 +  * [[dido:99_annexes:annex-b-terms-and-definitions:n:node_configuration|Node Configuration]]
 +  * [[dido:99_annexes:annex-b-terms-and-definitions:n:node_binding|Node Binding]]

 +  * [[dido:99_annexes:annex-b-terms-and-definitions:e:evidence|Evidence]]
 +  * [[dido:99_annexes:annex-b-terms-and-definitions:t:traceability|Traceability]]
 +
 +===== Verification =====
 +
 +Verification confirms that:
 +
 +  * The DIDO-TE uniquely identifies each Node subject to execution control.
 +  * The DIDO-TE identifies the Test Execution in which each Node participates.
 +  * The DIDO-TE identifies the Node Definition, Node Implementation, Node Configuration, and Test Definition governing each Node execution.
 +  * The DIDO-TE confirms that the Node has a current and successful validation result before authorizing execution.
 +  * The DIDO-TE confirms that the Node has a current and successful readiness result before authorizing execution.
 +  * The DIDO-TE confirms that each mandatory Node Binding and Test Resource is available before initiating execution.
 +  * The DIDO-TE authorizes each Node execution before initiating Node activity.
 +  * Each execution authorization identifies the responsible authority, target Node, Test Execution, permitted activity, parameters, constraints, and validity period.
 +  * The DIDO-TE prevents unauthorized, duplicate, conflicting, or out-of-sequence Node execution.
 +  * The DIDO-TE initiates Node execution through an identified and authorized procedure.
 +  * The DIDO-TE supplies each Test Input to the intended Node through its specified mechanism and in its required sequence.
 +  * The DIDO-TE coordinates Node execution with applicable Nodes, Node Bindings, Dependencies, and Test Resources.
 +  * The DIDO-TE observes the Node state, activity, interactions, resource use, and outputs during execution.
 +  * The DIDO-TE associates each observed Node activity and output with the applicable Node and Test Execution.
 +  * The DIDO-TE detects behavior that differs from the applicable Test Definition, Node Definition, Node Configuration, execution parameters, or authorized operating conditions.
 +  * The DIDO-TE detects a Node that becomes unready, unavailable, degraded, unresponsive, incorrectly configured, or disconnected during execution.
 +  * The DIDO-TE detects an unauthorized Node interaction, Test Input, output, resource use, or configuration change.
 +  * The DIDO-TE detects an unsuccessful, incomplete, interrupted, stalled, duplicated, or timed-out Node execution.
 +  * The DIDO-TE identifies and handles each applicable Test Execution Exception.
 +  * The DIDO-TE suspends, resumes, terminates, isolates, restarts, or recovers the Node only through an identified and authorized procedure.
 +  * The DIDO-TE determines the effect of a Node execution deviation or exception on affected Nodes, Test Inputs, Test Resources, Test Results, and Evidence.
 +  * The DIDO-TE prevents an unsuitable Node from continuing to participate in Test Execution.
 +  * The DIDO-TE confirms the resulting Node state when Node execution ends.
 +  * The DIDO-TE records the Node identity, Test Execution, authorization, procedure, configuration, inputs, parameters, interactions, observations, outputs, timing, resource use, state changes, findings, exceptions, actions, and resulting status.
 +  * Repeated execution of an unchanged Node under equivalent controlled conditions produces equivalent behavior and outputs within specified tolerances.
 +  * The DIDO-TE maintains Traceability among the Node Definition, Node Implementation, Node Configuration, Node Bindings, Test Definition, Test Inputs, Test Resources, execution authorization, Node activity, observations, outputs, exceptions, Test Results, and resulting Evidence.
 +  * An unauthorized, uncontrolled, incomplete, incorrectly sequenced, unobservable, or untraceable Node execution constitutes nonconformance with this requirement.
 +
 +Verification includes:
 +
 +  * Inspection of the Node identity and applicable Test Execution
 +  * Inspection of the governing Node Definition, Node Implementation, Node Configuration, and Test Definition
 +  * Confirmation of successful Node validation and readiness results
 +  * Inspection of the execution authorization and responsible authority
 +  * Observation of authorized Node execution
 +  * Observation of Test Input delivery and Node outputs
 +  * Observation of coordination with other Nodes, Node Bindings, Dependencies, and Test Resources
 +  * Confirmation that unauthorized or out-of-sequence execution is prevented
 +  * A negative assessment involving an unavailable mandatory Node Binding or Test Resource
 +  * A negative assessment involving an unauthorized Test Input or Node interaction
 +  * A negative assessment involving an unresponsive or degraded Node
 +  * A negative assessment involving an interrupted or timed-out Node execution
 +  * Confirmation that an unsuitable Node cannot continue participating in Test Execution
 +  * Repeated execution under equivalent controlled conditions
 +  * Inspection of execution records, findings, exceptions, Test Results, Evidence, and Traceability
