====== 9.15 FX Replay Request Topic Mapping ======
[[fxdemo:04-part:09-mapping-from-fx-logical-communication-endpoints-to-dds-topics:start | Go To Mapping from FX Logical Communication Endpoints to DDS Topics ]]
The FX Replay Request [[dido:99_annexes:annex-b-terms-and-definitions:l:logical_communication_endpoint|Endpoint]] maps to the [[dido:99_annexes:annex-b-terms-and-definitions:d:dds|DDS]] Topic that carries the Phase 0 implementation representation of FX Replay Request information.
**Table 9-12:** FX Replay Request Endpoint to DDS Topic mapping.
^ Mapping Concern ^ Phase 0 Implementation Treatment ^
| FX logical Communication Endpoint | FX Replay Request Endpoint |
| DDS Topic | Audit.FX.ReplayRequest |
| Primary information structure | FX Replay Request |
| IDL structure / generated type | Phase 0 representation of the FX Replay Request |
| Producing Node Roles | Replay requester; Registry and Coordination Role, where replay uses Control Plane coordination |
| Consuming Node Role | Replay and Reconstruction Role |
| Primary Runtime Plane | FX Logical Audit and Provenance Plane |
| Supporting Runtime Plane | FX Logical Control Plane |
| QoS profile family | Audit and Provenance Plane QoS profile |
| Traceability expectation | DDS Topic traces to the FX Replay Request Endpoint and the FX Replay Request. |
