An apparatus and method for operating an avionics data network includes a network switch core configured for a time-sensitive networking (TSN) schema, a set of TSN networking end nodes communicatively connected with the network switch core, a set of ARINC 664 part 7 (A664p7) networking end nodes communicatively connected with the network switch core, and an A664p7 legacy module connected with, or incorporated into, the network switch core and configured to receive a set of A664p7 networking data from the set of A664p7 networking end nodes.

Avionics data networks

Systems and methods for providing an efficient and configurable port interface in an avionics data transfer system are provided. For instance, in one embodiment a set of virtual ports associated with an avionics data transfer system can be defined. At least as a subset of the virtual ports can be mapped to one or more addresses in a memory space associated with the data transfer system, such that each virtual port has a fixed definition in the memory space. One or more of the virtual ports can then be associated with one or more physical ports associated with an interface between a host computing device and an end system in the data transfer system by specifying for the one or more virtual ports a plurality of port parameters that define the respective one or more physical ports.

Providing an interface for an avionics data transfer system

A method of synchronizing a local estimation of global network time of a receiving node on a network to a global network time reference is provided. The free running nodes receive precise time protocol synchronization messages and determine a ratio and an offset based on time data extracted from the messages.
