| 术语 | expedited flow |
| 释义 | expedited flow 加急(数据)流 In SNA, a data flow designated in the transmission header (TH) that is used to carry network control, session control, and various data flow control request／ response units (RUs); the expedited flow is separate from the normal flow (which carries primarily end-user data) and can be used for commands that affect the normal flow. 在系统网络体系结构(SNA)中,传输报头(TH)内指定的一种数据流,用于运载网络控制权、 话路控制权、及各种数据流控制的请求／应答单元(RU),加急流与正常流(主要运载末端用 户数据)有区别,且能用作对正常流起作用的命令。 Note:The normal and expedited flows move in both the primary-to-secondary and secondary-to-primary directions. Requests and responses on a given flow (normal or expedited) usually are processed sequentially within the path, but the expedited flow traffic may be moved ahead of the normal-flow traffic within the path at queuing points in the half-sessions and for half-session support in boundary functions. 注:正常流和加急流在主-次和次-主两个方向上流动。给定流(正常或(加急)上的应答和 请求在通路内通常按序处理,但是,在话路端和对边界功能中话路端的支持中,加急流通信在 排队点处通路内可以被移到正常流通信之前。 |
