JRDDP Packet Format

All JRDDP packets shall include a variable length header, followed by a variable length payload, followed by a 2-byte CRC Trailer. The figure below shows how the JRDDP packet is embedded within the standard SpaceWire packet. Note that while a SpaceWire packet may have zero or more destination addresses before the JRDDP header, the JRDDP requires that exactly one destination address be delivered to the protocol logic.
