1. A multi-core avionics processing resource (MCPR) comprising: a plurality of avionics processing cores coupled to at least one shared system memory, the plurality of avionics processing cores including: a single network core coupled to a first network protocol via a first network controller, the first network protocol including an Ethernet network, the single network core comprising: one or more partitions having at least one operating system configured to execute at least one first Ethernet operations request on the single network core, the at least one first Ethernet operations request associated with one or more of a first criticality level and a first priority level; a single Ethernet network stack associated with the Ethernet network and configured to execute one or more of the at least one first Ethernet operations request and at least one second Ethernet operations request on the single network core; and at least one flow control component configured to control access of the at least one first Ethernet operations request and the at least one second Ethernet operations request to resources of the single network core; and at least one application core coupled to a second network protocol via a second network controller, the at least one application core comprising: at least one application configured to generate the at least one second Ethernet operations request for execution on the single network core, the at least one application associated with one or more of a second criticality level and a second priority level; the at least one flow control component further configured for one or more of granting, denying, and truncating one or more of the at least one first Ethernet operations request and the at least one second Ethernet operations request based on one or more of the first criticality level, the first priority level, the second criticality level, and the second priority level; the at least one application core isolated from asynchronous Ethernet network traffic received by the single network core via the first network controller; the single network core isolated from second network protocol traffic received by the at least one application core via the second network controller; and at least one communications interface comprising: at least one network proxy associated with the at least one application core and configured to forward the at least one second Ethernet operations request to the at least one flow control component to fulfill one or more of the at least one first Ethernet operations request and the at least one second Ethernet operations request via the single Ethernet network stack and the shared system memory.
