一种基于IPX协议的油田控制网络

控制网络是一种用于生产过程的实时监测与控制的计算机网络,它对信息传输的实时性要求较高,但网络中信息的传输量不会太多。IPX是Novell公司开发的网际包交换协议,对应于OSI网络层,是一个无连接的协议,具有实时性好,独立于网络拓扑结构和传输媒质,既可实现点-点通信,也可实现多点或广播通信以及实用的应用编程接口(API)等特点。针对控制网络和IPX的以上特性,提出一种基于IPX协议的油田控制网络。该网络具有结构灵活、信息传输实时性好的特点,可方便地与信息网络集成,并讨论该控制网络应用软件的开发方法。

A Control network Based on IPX Protocol

Control network is a kind of computer networks used in real-time monitoring and production process controlling.In a control network, the quantity of information transmitted is not necessarily large, but the transmission time isrequired to be shortest. IPX is an internetwork package exchange protocol developed by Novell Cooperation. It is a connectionless network layer protocol, and is featured by good real-time transmission and being independent of the network and the transmission media; it can permit information exchange on a point-to-point basis as well as on a multi-point or broadcasting basis. In view of the above characteristics of control network and IPX, We developed a control network based on IPX protocol. This network is characterized by flexible networking and rapid transmission, and it can be conveniently integrated with information networks. The design of the applica-tion software of this network is discussed.
