The resulting system is structured in line with the logical model presented in the ECSS 'Telemetry & Telecommand Packet Utilization' standard:

Blue boxes represent application processes.
Green boxes are supporting elements concerned with onboard traffic management.
Red ovals are external systems.
Cyan boxes are shared platform specific components.

A short introduction is given to each of the components.
 Ground
Represents the ground segment with one or more control centers.
 Ground I/F
Special application process managing the interface to the ground segment. Implements any protocols applicable to the uplink and downlink (e.g. 'Packet Telecommand Standard', Packet Telemetry Standard').
Transforms received telecommand source packets into an internal representation, forwarding these to the Packet Router. Transforms generated telemetry source packets into the external format forwarding these to Ground.
Such an application process is present in all data handling systems developed based on the reusable software components.
 Packet Router
Responsible for routing of source packets between application processes.
 Payload
Application process providing a collection of Telemetry & Telecommand Packet Utilization services as would be required for an imaging payload.
Power Conditioning System
Application process providing a collection of Telemetry & Telecommand Packet Utilization services as would be required for an Electrical Power Conditioning & Distribution Unit.
Data Handling System
Application process providing a collection of Telemetry & Telecommand Packet Utilization services related to the data handling system platform and overall mission management.
Onboard Storage
Implements a single instance of the Onboard Storage & Retrieval Service.
It is anticipated that only one instance of such a service will exist onboard.
Onboard Bus
Device drivers interfacing to one or more onboard busses.
Implements communication protocols and controls hardware interfaces.
