Interconnection fabric with protocol agnostic switch for flexible radio avionics

A radio system comprising:

• a plurality of software defined radio units;
• a plurality of digital data switches each in operative communication with at least one of the radio units, the digital data switches operatively connected to each other;
• a plurality of antenna units each in operative communication with at least one of the radio units through at least one of the digital data switches;
• and
• a plurality of radio resources managers each operatively coupled to one or more of the digital data switches, each of the radio resources managers configured to control one or more of the digital data switches to route digital data between the radio units and the antenna units;
• wherein each of the digital data switches is configured to receive control information from each of the radio resources managers;
• wherein the digital data switches support a failure-tolerant multi-master control scheme that provides a voting or other redundancy management mechanism that is activated when one of the radio resources managers has corrupted or missing control information.
