您可以使用本主题来了解 QoS 策略的体系结构。You can use this topic to learn about the architecture of QoS Policy.

下图显示了基于策略的 QoS 的体系结构。The following figure shows the architecture of Policy-based QoS.

QoS 策略的体系结构

基于策略的 QoS 的体系结构包括以下组件:The architecture of Policy-based QoS consists of the following components:

  • 组策略客户端服务Group Policy Client Service. 一种 Windows 服务,用于管理用户和计算机配置组策略设置。A Windows service that manages user and computer configuration Group Policy settings.

  • 组策略引擎Group Policy engine. 组策略客户端服务的一个组件,用于在启动时从 Active Directory 检索用户和计算机配置组策略设置,并在 ( 默认情况下每隔90分钟定期检查更改 ) 。A component of the Group Policy Client Service that retrieves user and computer configuration Group Policy settings from Active Directory upon startup and periodically checks for changes (by default, every 90 minutes). 如果检测到更改,组策略引擎将检索新的组策略设置。If changes are detected, the Group Policy engine retrieves the new Group Policy settings. 当更新 QoS 策略时,组策略引擎处理传入的 Gpo 并通知 QoS 客户端扩展。The Group Policy engine processes the incoming GPOs and informs the QoS Client Side Extension when the QoS policies are updated.

  • QoS 客户端扩展QoS Client Side Extension. 组策略客户端服务的一个组件,它等待来自组策略引擎的指示 QoS 策略已更改并通知 QoS 检测模块。A component of the Group Policy Client Service that waits for an indication from the Group Policy engine that the QoS policies have changed and informs the QoS Inspection Module.

  • Tcp/ip 堆栈TCP/IP Stack. TCP/IP 堆栈,其中包括对 IPv4 和 IPv6 的集成支持,并支持 Windows 筛选平台。The TCP/IP stack that includes integrated support for IPv4 and IPv6 and supports Windows Filtering Platform.

  • QoS 检查QoS Inspection. 模块一个 TCP/IP 堆栈内的组件,该组件等待 qos 客户端扩展中的 QoS 策略更改的指示,检索 QoS 策略设置,并与传输层进行交互,并 Pacer.sys 内部标记与 QoS 策略匹配的流量。Module A component within the TCP/IP stack that waits for indications of QoS policy changes from the QoS Client Side Extension, retrieves the QoS policy settings, and interacts with the Transport Layer and Pacer.sys to internally mark traffic that matches the QoS policies.

  • NDIS1.x。NDIS 6.x. 内核模式网络驱动程序与 Windows Server 和客户端操作系统中的操作系统之间的标准接口。A standard interface between kernel-mode network drivers and the operating system in Windows Server and Client operating systems. NDIS 1.x 支持轻型筛选器,这是一个简化的用于 NDIS 中间驱动程序和微型端口驱动程序的驱动程序模型,可提供更好的性能。NDIS 6.x supports lightweight filters, which is a simplified driver model for NDIS intermediate drivers and miniport drivers that provides better performance.

  • **QoS 网络提供程序接口 (NPI ) **。QoS Network Provider Interface (NPI). 用于与 Pacer.sys 进行交互的内核模式驱动程序的接口。An interface for kernel-mode drivers to interact with Pacer.sys.

  • Pacer.sysPacer.sys. 一种 NDIS 1.x 轻型筛选器驱动程序,用于控制基于策略的 QoS 的数据包计划,以及使用一般 QoS ( GQoS ) 和流量控制 ( TC api 的应用程序的流量 ) 。An NDIS 6.x lightweight filter driver that controls packet scheduling for Policy-based QoS and for the traffic of applications that use the Generic QoS (GQoS) and Traffic Control (TC) APIs. Pacer.sys 替换 Windows Server 2003 和 Windows XP 中的 Psched.sys。Pacer.sys replaced Psched.sys in Windows Server 2003 and Windows XP. Pacer.sys 与 QoS 数据包计划程序组件一起安装在网络连接或适配器的属性中。Pacer.sys is installed with the QoS Packet Scheduler component from the properties of a network connection or adapter.
