基于流程编程
在电脑编程中，基于流程（flow-based）编程，缩写为FBP，是一种编程范型，它将应用定义为黑箱进程的网络，它们经过预先定义的连接，通过消息传递来交换数据，而这里的连接是在“外部”指定给进程的。这些黑箱进程不需要更改内部，就可以无尽的重新连接而形成不同的应用。FBP因而是天然基于构件的。
历史
编辑基于流程编程由J. Paul Morrison在1970年代前期发明，最初实现于为加拿大银行开发的软件中[2]。FBP在初起阶段受到同期的一些IBM模拟语言的强烈影响，特别是GPSS，但是它的根基完全一致于康威关于协程的开创性论文[3]。
概念
编辑下列框图展示了FBP框图的主要实体（资讯包除外）。这种框图可以直接转换成一个连接的列表，接着它们可以在适当的引擎（软件或硬件）上执行：
A、B和C是执行代码构件的处理器。O1、O2和两个IN是端口，它们将连接M和N链接到与它们有关的处理器上。允许处理器B和C执行相同的代码，每个处理器必须有自己的工作存储、控制块等的集合。不管它们共享代码与否，B和C自由的使用相同的端口名字，因为端口名字只在引用它们的构件内有意义（当然是在网络层面上）。
M和N经常被称为“有界缓冲区”，在任何时间点上能持有的资讯包（IP）的数目方面，它们有着固定的能力。
“端口”的概念是为允许同一个构件在一个网络上用在多于一个位置上。结合了叫做初始化资讯包（IIP）的参数化能力，端口向FBP提供了构件重用功能，使得FBP成为基于构件的架构。FBP从而展示了IBM研究院的Raoul de Campo和Nate Edwards所称谓的“可配置的模块化”。
