术语	path control layer
释义	path control layer 通路控制层 In SNA, the layer that manages the sharing of link resource of the SNA network and routes basic information units (BIUs) through it. Path control routes message units between network addressable units( NAUs) in the network and provides the paths between them. It converts the BIUs from transmission control (possibly segmenting then) into path information units (PIUs) and exchanges basic transmission units (BTUs)one or more PIUswith data link control. Note: The unit of control information built by the sending path control component is the transmission header (TH), attached to the BTU;the TH is interpreted by the receiving path control component. The path control layer in subarea nodes consists of explicit route control, transmission group control, virtual route control, and boundary function path control. 在系统网络体系结构(SNA)中,管理共享SNA网络的链路资源并为基本信息单元(BIU)通过该网络选择路由的控制层。路径控制程序在网络中的可寻址单元(NAU)之间为报文单元选择路由, 并在它们之间提供通路。它把从传输控制程序送来的基本信息单元(BIU)变换(可能把它们分段)为路径信息单元(PIU), 并将基本传送单元(BTU,指一个或多个路径信息单元PIU)与数据链路控制程序进行交换。注:由发送路径控制部件所建立的控制信息单元是附加到基本传送单元上的传输报头 (TH), 这个传输报头由接收路径控制程序解释。子区网点中的路径控制层包括显式路由控制程序、传输组控制程序、虚拟路由控制程序和边界操作路径控制程序。参阅BIU segment,blocking of PIUs, data link control layer, transmission control (TC) layer。
