Application Research Of IEEE1394 Serial Bus Protocol On The Ethernet

With the rapid development of computer bus technology,and the popularization of computer and consumer electronics products,the requirements of electronic products to the information data transmission speed,bandwidth,the real-time and the stability greatly improve.As a standard of data transmission, IEEE1394 bus has characteristics of high-speed transmission,high-bandwidth capacity and good scalability,and plug-and-play,bus dynamic configuration and other features,which is becoming one of the extensive application buses in the field of data transmission.In IEEE-1394 network to see the rapid development of the traditional Ethernet can not ignore the dominant situation.Combined with the practical needs of units,the author of the IEEE1394 serial bus protocol in the application of Ethernet technology in the study.This dissertation introduces the technical characteristics and architecture of IEEE1394 high-performance serial bus,and analyses the asynchronous and isochronous transmission mode,including the protocol hierarchical structure, transmission interface and the data-copy and implementation in the process of data sending and receiving.In view of high-speed transmission features of the 1394 interface,on the basis of understanding and mastering IEEE1394 architecture, communications model and data transmission,this dissertation designs and implements the Ethernet transmitting and heterogeneous multi-network cards bonding technology based on IEEE1394 serial bus protocol.Through modifying IEEE1394 Ethernet drivers and combined with the bonding driver model in Linux system,it achives to transmit data in both of Ethernet and 1394 net,which improves the usability of data transmitting.
