C4ISR solution based on 10-gigabit Ethernet and RapidIO

　C4ISR is an acronym for command, control, communications, computer, intelligence, and surveillance and reconnaissance. The C4ISR system is a man-machine system which combines the technology of computer with the commanding personnel to command and control the troops and weapons. In the 1950s command automation was called the C2(command and control) system. In the 1960s, with the development of communication technology, C3(command, control and communication) system was formed by adding “Communication”to the system. In 1977, the United States first “Intelligence”as an indispensable element of command automation, and with the C3 system, the formation of C3i (command, control, communications and intelligence) system. Later, due to the increasing role of computers in the system, command automation was added “Computer”, into a C4I (command, control, communication, computer and intelligence) system. In recent years, continuous local wars have made people realize the importance of mastering battlefield situation, and put forward the concept of “Battlefield perception”, therefore, the C4I system has further evolved into a C4ISR (command, control, communication, computer and intelligence, surveillance, reconnaissance) system which includes “Surveillance”and “Reconnaissance”.
