Secondary core ONU to OLT via internal EPON bus coupled multi-core processor for integrated modular avionic system

An integrated modular avionics (IMA) system, comprising:

• a) a plurality of multi-core processor systems, each comprising:
• i) a main processor, comprising:
• 1. a processing unit configured to function as a host processor for main processor avionics functions;
• 2. an offload engine operatively connected to said processing unit for routing data to and from said processing unit;
• 3. a plurality of main processor optical network units (ONU's) operatively connected to said offload engine and,
• 4. a dual optical line terminal (OLT) operatively connected to said offload engine;
• ii) an internal EPON bus operatively connected to said OLT;
• and,
• iii) a plurality of secondary core processors, located physically separate from said main processor, each secondary core processor having a respective secondary core ONU being operatively connected to said main processor via said internal EPON bus, said internal EPON bus being the only connection point for the secondary core processors to the main processor, thus the internal EPON bus is configured as a separate EPON tree from an external EPON bus of the main processor;
• and,
• b) a plurality of remote data concentration components operatively connected to said plurality of multi-core processor systems via an external EPON bus connected to said dual OLTs of said plurality of multi-core processors, wherein failure of one or more of said plurality of secondary core processors does not effect the external EPON bus functionality.
