Reference topology for the Orion Crew Exploration Vehicle network.

The Orion Crew Exploration Vehicle (CEV) reference models a published mixed-criticality embedded network with end systems and switching nodes. The topology includes multiple layers of avionics switches, distributed units, controllers, and mission subsystems, all connected through a fixed embedded communication backbone.

Its featured capabilities are those of a structured mixed-criticality network: deterministic switch-centric connectivity, explicit separation between end systems and network switches, and link/node resources suitable for analysing QoS constraints such as latency, bandwidth, and availability in a safety-oriented setting.
