摘要
DECnet网络允许运行在网络不同节点上的两个程序或任务通过逻辑链路交换数据。两个通讯的程序或任务之间的逻辑链路类似于一个I/O通道。链路上的程序均可发送与接收数据。DECnet网络系统任务——任务的通讯程序执行的几个功能包括:请求一个逻辑链接、接受或拒绝逻辑链接请求、发送与接收数据、终止逻辑链接。此外,还可发送中断数据、接收中断数据。文章中给出实现任务——任务之间通讯的实例。
DECnet enable two programs or tasks to run on different nodes in a network to ex- change data over a logical link.The logical link between the two communicating programs or tasks is like an I/O channel over which both programs can send and receive data. DECnet task-to-task calls in communicating programs perform several functions,in- cluding requesting a logical link,accepting or rejecting a logical link request,sending and receiving data and terminating the link.In addition,it can send interrupt data,and receive interrupt.In this paper,we discuss an instance about performing task-to-task communi- cation.
