SpaceWire is integrated networking technology where the data packets and control traffic in the form of hard real-time signals are transmitted throw the same links of communication network. Last decades for hard real-time signals transmission in onboard networks the specialized buses like CAN and MIL-STD 155b and sideband signals were used. All buses have the property that the signal from the source node to all other nodes propagates simultaneously, so there is no jitter for signal delivery. When the industry moves to a common communication medium for control and data traffic transmission through network with routing switches and point-to-point connections, there is a problem of synchronization hard real-time signals delivery from the source to all other nodes because of different distance (number of switches and link speeds in a path) between source and receiver. There are many different algorithms and methods for the system time synchronization. In this paper we consider the questions of delivery synchronization of distributed interrupts which intended to control and inform the devices about critical system events in hard real-time.
