An optimization for packet delivery in integrated avionics systems

In integrated avionics systems, sub-systems and/or modulars are interconnected by packet-passing routers and switches. Therefore, some multiplexers or shared ports become critical resource for inter-communication tasks. For some cases such as nonblocking state data delivery and processing, we adopt max-plus algebra to describe the behavior of packet passing, so that the case, which is man-made and seriously non-linear, can be looked as a linear system. Being analogue in modern control theory, state space matrixes are applied in quantitative analyses. And even, packet delivery intervals are set in term of optimal feedback control schedule under the performance criteria.
