The FX Demo Logical Communication Model specializes the Part 2 [[dido:99_annexes:annex-b-terms-and-definitions:l:logical_communication_endpoint|Logical Communication Model]] for the [[dido:99_annexes:annex-b-terms-and-definitions:f:foreign_exchange_domain|Foreign Exchange Domain]].

An FX logical [[dido:99_annexes:annex-b-terms-and-definitions:l:logical_communication_endpoint|Communication Endpoint]] identifies a platform-independent point of information exchange among FX logical [[dido:99_annexes:annex-b-terms-and-definitions:l:logical_node|Nodes]]. Each endpoint identifies the participating FX logical [[dido:99_annexes:annex-b-terms-and-definitions:l:logical_node|Nodes]] or [[dido:99_annexes:annex-b-terms-and-definitions:l:logical_node_role|Node Roles]], [[dido:99_annexes:annex-b-terms-and-definitions:c:communication_role|Communication Roles]], FX logical information structures, [[dido:99_annexes:annex-b-terms-and-definitions:r:runtime_plane|Runtime Plane]] classification, governance constraints, and [[dido:99_annexes:annex-b-terms-and-definitions:t:traceability|Traceability]] or [[dido:99_annexes:annex-b-terms-and-definitions:e:evidence|Evidence]] expectations.

The FX Demo Logical Communication Model does not prescribe [[dido:99_annexes:annex-b-terms-and-definitions:d:dds|DDS]] Topics, [[dido:99_annexes:annex-b-terms-and-definitions:r:rest|REST]] resources, [[dido:99_annexes:annex-b-terms-and-definitions:r:rpc|RPC]] methods, [[dido:99_annexes:annex-b-terms-and-definitions:p:protocol_buffers|Protocol Buffers]] services, message queues, event streams, files, database handoffs, shared-memory locations, or network routes. Implementation profiles select the mechanisms used to realize FX logical [[dido:99_annexes:annex-b-terms-and-definitions:l:logical_communication_endpoint|Communication Endpoints]].

Figure 8-1 summarises the primary FX logical Communication Endpoints.
