 +====== ENV-004i — Control Communication Conditions ======
  
 +[[dido:03-dido-te:99-annexes:annex-c-requirements:03-functional-requirements:03-01-test-environment-requirements:env-004-provide-deterministic-test-environment:start|Go to ENV-004 — Provide Deterministic Test Environment]]
 +
 +===== Statement =====
 +
 +The [[dido:99_annexes:annex-b-terms-and-definitions:d:dido-te|DIDO-TE]] SHALL control communication conditions in accordance with the applicable [[dido:99_annexes:annex-b-terms-and-definitions:t:test_definition|Test Definition]].
 +
 +===== Derived From =====
 +
 +  * [[dido:03-dido-te:99-annexes:annex-c-requirements:03-functional-requirements:03-01-test-environment-requirements:env-004-provide-deterministic-test-environment:start|ENV-004 — Provide Deterministic Test Environment]]
 +  * [[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 =====
 +
 +Communication conditions influence message delivery, event ordering, synchronisation, availability, throughput, latency, and the behaviour of distributed [[dido:99_annexes:annex-b-terms-and-definitions:n:node|Nodes]].
 +
 +Relevant conditions include latency, jitter, bandwidth, loss, duplication, corruption, reordering, interruption, routing, addressing, protocol behaviour, and connection state.
 +
 +Uncontrolled differences in these conditions introduce environmental variation into a [[dido:99_annexes:annex-b-terms-and-definitions:t:test_execution|Test Execution]].
 +
 +The applicable Test Definition distinguishes conditions requiring direct control from conditions requiring measurement and recording.
 +
 +===== Applies To =====
 +
 +  * [[dido:99_annexes:annex-b-terms-and-definitions:t:test_environment|Test Environment]]
 +  * [[dido:99_annexes:annex-b-terms-and-definitions:t:test_definition|Test Definition]]
 +  * [[dido:99_annexes:annex-b-terms-and-definitions:t:test_execution|Test Execution]]
 +  * [[dido:99_annexes:annex-b-terms-and-definitions:t:test_object|Test Object]]
 +  * [[dido:99_annexes:annex-b-terms-and-definitions:n:node|Node]]
 +  * [[dido:99_annexes:annex-b-terms-and-definitions:t:test_resource|Test Resource]]
 +  * [[dido:99_annexes:annex-b-terms-and-definitions:c:configuration|Configuration]]
 +  * [[dido:99_annexes:annex-b-terms-and-definitions:c:constraint|Constraint]]
 +  * [[dido:99_annexes:annex-b-terms-and-definitions:e:evidence|Evidence]]
 +
 +===== Verification =====
 +
 +Verification confirms that:
 +
 +  * The applicable Test Definition identifies each communication path that influences the Test Execution.
 +  * Each communication path has a unique identity.
 +  * Each communication path identifies its endpoints, interfaces, protocols, and applicable network boundaries.
 +  * The Test Definition specifies the required communication conditions for each path.
 +  * Each specified condition identifies its required value, range, state, or tolerance.
 +  * The DIDO-TE applies each required communication condition.
 +  * The DIDO-TE measures actual communication conditions during Test Execution.
 +  * The DIDO-TE detects conditions outside the specified tolerances.
 +  * The DIDO-TE records communication-path identities, configurations, measurements, changes, interruptions, and detected deviations as [[dido:99_annexes:annex-b-terms-and-definitions:e:evidence|Evidence]].
 +  * The DIDO-TE maintains [[dido:99_annexes:annex-b-terms-and-definitions:t:traceability|Traceability]] among each communication condition, the affected communication path, the Test Definition, the Test Execution, the Evidence, and the [[dido:99_annexes:annex-b-terms-and-definitions:t:test_result|Test Results]].
 +  * An unidentified, uncontrolled, unmeasured, unsupported, or untraceable communication condition constitutes nonconformance with this requirement.
 +
 +Verification includes:
 +
 +  * Inspection of the communication paths identified by the Test Definition
 +  * Inspection of endpoints, interfaces, protocols, network boundaries, and required communication conditions
 +  * Comparison of required and applied communication conditions
 +  * Measurement of communication conditions during Test Execution
 +  * A negative assessment using latency or jitter outside the specified tolerance
 +  * A negative assessment introducing loss, duplication, corruption, reordering, or interruption
 +  * Confirmation that the DIDO-TE detects and records each deviation
 +  * Inspection of communication Evidence and Traceability records
 +  * Confirmation that each negative assessment produces a nonconformance result
 +
 +===== Referenced By =====

 +{{backlinks>.}}
 +
 +===== Related Architecture Sections =====
 +
 +  * Add links to the architecture sections governing communications, network control, fault injection, monitoring, Evidence, and Traceability.
 +
 +===== Delivery Phase =====
 +
 +Assign the applicable delivery phase.
