The present disclosure relates to the technical field of
bus communication, and provides a networking
system and method based on IEEE 1394 protocol. The
system comprises a central hub, a target hub and a target terminal device. The central hub comprises a plurality of central connection ports, and there is an intercommunication
data link between each two of the central connection ports. The target hub comprises a target uplink port, which is connected to one of the central connection ports through a target cable complying with IEEE 1394 technical specification. The target terminal device is connected to one of the target downlink ports of the target hub through a target cable. If a first connection port of the central connection ports receives a data packet sent by the target terminal device, the central hub forwards the data packet to a second connection port of the central connection ports based on a load balancing
algorithm. The technical scheme provided by one or more embodiments of the present disclosure can effectively integrate the device resources of multiple hubs.
