摘　　要：利用计算机网络技术建造石油局域网可以为油田的发展提供强有力的工具 ,而建造局域网的重要问题之一是局域网中主干网的选择。光纤分布数据接口是高速网络中最成熟的商品化技术之一 ,由于其成本的不断降低 ,非常适合用做高速数字通信的主干网。文中讨论了FDDI的体系结构 ,媒体访问介质的功能 ,物理层的逻辑结构和功能以及站管理功能。提出了选择FDDI做石油局域网的主干网 ,选择路由器作为主网与子网互连设备 ,采用双环树型的拓扑结构以满足不断增长的主干网的需要。Petroleum local network builded by computer network technology provides a strong means for oilfield development. One of important problem for building local network is the choice of trunk network of local network. Fiber distributed data interface (FDDI) is one of the most mature commercialization technology of high speed digital communication. FDDI is fit trunk network because of its cheaper and cheaper cost. The architecture of FDDI, medium access function, physical logical structure and function and station management function are described. It is proposed to choose FDDI as trunk network of petroleum local network. The interconnection equipment of trunk network and sub-network uses topology of local network in order to satisfy the needs of increasing trunk network.
