Converged avionics data network

A converged avionics data network comprising:

• a network switch core;
• and
• a first set of networking end nodes and a second set of networking end nodes, communicatively coupled with the network switch core, the first set of networking end nodes including a first subset of networking end nodes configured for a first schema and second subset of networking end nodes configured for a second schema, wherein the second schema is a time-sensitive network (TSN) schema, and the first subset of networking end nodes are otherwise incompatible with the TSN schema;
• wherein the network switch core is configured to:
• receive, from the first set of networking end nodes, a set of data frames;
• determine the respective schema of the set of data frames;
• police the set of data frames based on the determined respective schema in accordance with at least one of IEEE Std. 802.1Qbv and ARINC Specification 664 part 7;
• forward the set of data frames to a predetermined queue on an egress port of the network switch core based on the determined respective schema;
• and
• shape a transmission of the set of data frames based on the predetermined queue using a time aware shaper (TAS) having a predefined cycle time;
• and
• transmit the set of data frames to an end node of the second set of networking end nodes having a corresponding schema.
