As many previous ITS-related data networks have involved second-by-second real-time requirements over low speed data links, LAN network protocols have not been suitable. With He trend toward distributed intelligence and hider capacity communication links, Be real-time control aspects will be relaxed to permit less stringent monitoring of status and performance.
