Configuration Manager 中内容管理的基本概念Fundamental concepts for content management in Configuration Manager

适用范围:Configuration Manager (Current Branch)Applies to: Configuration Manager (current branch)

Configuration Manager 支持可靠的工具和选项系统来管理软件内容。Configuration Manager supports a robust system of tools and options to manage software content. 软件部署(如应用程序、包、软件更新和 OS 部署)都需要内容。Software deployments such as applications, packages, software updates, and OS deployments all need content. Configuration Manager 将内容存储在站点服务器和分发点上。Configuration Manager stores the content on both site servers and distribution points. 在不同位置间传输此内容时需要大量网络带宽。This content requires a large amount of network bandwidth when it's being transferred between locations. 为有效地规划和使用内容管理基础结构,首先了解可用选项和配置。To plan and use the content management infrastructure effectively, first understand the available options and configurations. 然后考虑如何使用它们以最好地适应网络环境和内容部署需求。Then consider how to use them to best fit your networking environment and content deployment needs.

提示

要详细了解内容分发进程以及帮助诊断和解决常规内容分发问题,请参阅了解和解决 Microsoft Configuration Manager 中的内容分发问题For more information about the content distribution process and to find help in diagnosing and resolving general content distribution problems, see Understanding and Troubleshooting Content Distribution in Microsoft Configuration Manager.

以下部分是内容管理的重要概念。The following sections are key concepts for content management. 当概念需要额外或复杂的信息时,将提供链接以将你转到这些详细信息。When a concept requires additional or complex information, links are provided to direct you to those details.

用于内容管理的帐户Accounts used for content management

以下帐户可用于内容管理:The following accounts can be used with content management:

网络访问帐户Network access account

由客户端用于连接到分发点和访问内容。Used by clients to connect to a distribution point and access content. 默认先尝试计算机帐户。By default, the computer account is tried first.

拉取分发点还使用此帐户从远程林中的源分发点下载内容。This account is also used by pull-distribution points to download content from a source distribution point in a remote forest.

某些方案不再需要网络访问帐户。Some scenarios no longer require a network access account. 可使站点搭配使用增强型 HTTP 和 Azure Active Directory 身份验证。You can enable the site to use Enhanced HTTP with Azure Active Directory authentication.

有关详细信息,请参阅网络访问帐户For more information, see Network access account.

包访问帐户Package access account

默认情况下,Configuration Manager 向通用访问帐户“用户”和“管理员”授予访问分发点上的内容的权限。By default, Configuration Manager grants access to content on a distribution point to the generic access accounts Users and Administrators. 但是,你可以配置其他权限来限制访问。However, you can configure additional permissions to restrict access.

有关详细信息,请参阅包访问帐户For more information, see Package access account.

带宽限制和计划Bandwidth throttling and scheduling

限制和计划选项均可帮助你控制将内容从站点服务器分发到分发点的时间。Both throttling and scheduling are options that help you control when content is distributed from a site server to distribution points. 这些功能类似于站点到站点基于文件的复制的带宽控制,但二者又没有直接关系。These capabilities are similar to, but not directly related to bandwidth controls for site-to-site file-based replication.

有关详细信息,请参阅管理网络带宽For more information, see Manage network bandwidth.

二进制差异复制Binary differential replication

Configuration Manager 使用二进制差异复制 (BDR) 更新以前分发到其他站点或远程分发点的内容。Configuration Manager uses binary differential replication (BDR) to update content that you previously distributed to other sites or to remote distribution points. 要支持 BDR 减少对带宽的使用,请在分发点上安装“远程差分压缩”功能。To support BDR's reduction of bandwidth usage, install the Remote Differential Compression feature on distribution points. 有关详细信息,请参阅分发点先决条件For more information, see Distribution point prerequisites.

BDR 将用于发送已分发内容更新的网络带宽降至最低。BDR minimizes the network bandwidth used to send updates for distributed content. 每次更改文件时,它仅重新发送新的或更改的内容,而不是发送整个内容源文件集。It resends only the new or changed content instead of sending the entire set of content source files each time you change those files.

如果使用 BDR,Configuration Manager 将标识对以前已分发的每个内容集的源文件所做的更改。When BDR is used, Configuration Manager identifies the changes that occur to source files for each set of content that you previously distributed.

  • 当源内容中的文件发生更改时,站点会创建内容的新增量版本。When files in the source content change, the site creates a new incremental version of the content. 然后,它仅将更改的文件复制到目标站点和分发点。It then replicates only the changed files to destination sites and distribution points. 如果重命名、移动了该文件,或更改了其内容,则将该文件视为已更改。A file is considered changed if you renamed or moved it, or if you changed the contents of the file. 例如,替换了以前分发到若干站点的驱动程序包的一个驱动程序文件,则只会复制更改的驱动程序文件。For example, if you replace a single driver file for a driver package that you previously distributed to several sites, only the changed driver file is replicated.

  • 在重新发送整个内容集之前,Configuration Manager 最多支持五个内容集增量版本。Configuration Manager supports up to five incremental versions of a content set before it resends the entire content set. 第五次更新后,对内容集的下一次更改会使该站点创建新版本的内容集。After the fifth update, the next change to the content set causes the site to create a new version of the content set. Configuration Manager 分发新版本的内容集以替换上一个内容集和其任何增量版本。Configuration Manager then distributes the new version of the content set to replace the previous set and any of its incremental versions. 分发新的内容集后,对源文件进行的后续增量更改会再次通过 BDR 进行复制。After the new content set is distributed, later incremental changes to the source files are again replicated by BDR.

支持在层次结构中的每个父站点和子站点之间进行 BDR。BDR is supported between each parent and child site in a hierarchy. 在站点内,支持在站点服务器及其常规分发点之间进行 BDR。BDR is supported within a site between the site server and its regular distribution points. 但是,拉取分发点和云分发点不支持通过 BDR 来传输内容。However, pull-distribution points and cloud distribution points don't support BDR to transfer content. 拉取分发点支持文件级增量,传输新的文件,但不是文件内的块。Pull-distribution points support file-level deltas, transferring new files, but not blocks within a file.

应用程序始终使用二进制差异复制。Applications always use binary differential replication. BDR 对于包是可选的,默认情况下未启用。BDR is optional for packages and isn't enabled by default. 要对包使用 BDR,请为每个包启用此功能。To use BDR for packages, enable this functionality for each package. 创建或编辑包时,选择“启用二进制差异复制”选项。Select the option Enable binary differential replication when you create or edit a package.

BDR 或增量复制BDR or delta replication

以下列表汇总了二进制差异复制 (BDR) 与增量复制之间的差异。The following lists summarize the differences between binary differential replication (BDR) and delta replication.

二进制差异复制的摘要Summary of binary differential replication

  • Windows 远程差分压缩的 Configuration Manager 术语Configuration Manager's term for Windows Remote Differential Compression
  • 块级差异Block-level differences
  • 始终为应用启用Always enabled for apps
  • 在旧包上可选Optional on legacy packages
  • 如果某个文件已存在于分发点上,并且发生了更改,则站点将使用 BDR 复制块级更改,而不是整个文件。If a file already exists on the distribution point, and there's a change, the site uses BDR to replicate the block-level change instead of the entire file. 仅当允许对象使用 BDR 时,此行为才适用。This behavior only applies when you enable the object to use BDR.

增量复制的摘要Summary of delta replication

  • 文件级差异File-level differences
  • 默认情况下,不可配置On by default, not configurable
  • 当包发生更改时,站点将检查对单个文件而不是整个包的更改。When a package changes, the site checks for changes to the individual files instead of the entire package.
    • 如果文件发生更改,请使用 BDR 来完成工作If a file changes, use BDR to do the work
    • 如果有新文件,请复制该新文件If there's a new file, copy the new file

对等缓存技术Peer caching technologies

建议Recommendations

  • 新式管理:如果已使用 Intune 等新式工具,请实现传递优化Modern management: If you're already using modern tools such as Intune, implement Delivery Optimization

  • Configuration Manager 和共同管理:使用对等缓存和传递优化的组合。Configuration Manager and co-management: Use a combination of peer cache and Delivery Optimization. 使用具有本地分发点的对等缓存,并对云方案使用传递优化。Use peer cache with on-premises distribution points, and use Delivery Optimization for cloud scenarios.

  • 已实现现有 BranchCache:并行使用所有三种技术。Existing BranchCache implemented: Use all three technologies in parallel. 对 BranchCache 不支持的方案使用对等缓存和传递优化。Use peer cache and Delivery Optimization for scenarios that aren't supported by BranchCache.

BranchCacheBranchCache

BranchCache 是一项 Windows 技术。BranchCache is a Windows technology. 支持 BranchCache 且下载了为 BranchCache 配置的部署的客户端随后可充当其他启用了 BranchCache 的客户端的内容源。Clients that support BranchCache, and have downloaded a deployment that you configure for BranchCache, then serve as a content source to other BranchCache-enabled clients.

例如,有运行 Windows Server 2012 或更高版本的分发点,并将其配置为 BranchCache 服务器。For example, you have a distribution point that runs Windows Server 2012 or later, and is configured as a BranchCache server. 当第一个启用 BranchCache 的客户端向此服务器请求内容时,客户端将下载并缓存该内容。When the first BranchCache-enabled client requests content from this server, the client downloads that content and caches it.

  • 然后,该客户端可以使内容可用于同一子网上的其他启用 BranchCache 的客户端,这些客户端也会缓存该内容。That client then makes the content available for additional BranchCache-enabled clients on the same subnet that also cache the content.
  • 同一子网上的其他客户端无需从分发点下载内容。Other clients on the same subnet don't have to download content from the distribution point.
  • 该内容分布在多个客户端,以供将来传输。The content is distributed across multiple clients for future transfers.

有关详细信息,请参阅对 Windows 10 BranchCache 的支持For more information, see Support for Windows BranchCache.

传递优化Delivery Optimization

使用 Configuration Manager 边界组来定义和控制跨公司网络和到远程办公室的内容分发。You use Configuration Manager boundary groups to define and regulate content distribution across your corporate network and to remote offices. Windows 传递优化是一种基于云的对等技术,用于在 Windows 10 设备之间共享内容。Windows Delivery Optimization is a cloud-based, peer-to-peer technology to share content between Windows 10 devices. 配置传递优化以在对等方之间共享内容时使用边界组。Configure Delivery Optimization to use your boundary groups when sharing content among peers. 客户端设置将边界组标识符用作客户端上的传递优化组标识符。Client settings apply the boundary group identifier as the Delivery Optimization group identifier on the client. 当客户端与传递优化云服务进行通信时,它使用此标识符来查找具有内容的对等方。When the client communicates with the Delivery Optimization cloud service, it uses this identifier to locate peers with the content. 有关详细信息,请参阅传递优化客户端设置。For more information, see delivery optimization client settings.

对于 Windows 10 质量更新,传递优化是优化 Windows 10 更新传递快速安装文件的推荐技术。Delivery Optimization is the recommended technology to optimize Windows 10 update delivery of express installation files for Windows 10 quality updates. 从 Configuration Manager 版本 1910 开始,需具有对传递优化云服务的 Internet 访问权限,才能利用其对等功能。Starting in Configuration Manager version 1910, Internet access to the Delivery Optimization cloud service is a requirement to utilize its peer-to-peer functionality. 有关所需的 Internet 终结点的信息,请参阅有关传递优化的常见问题For information about the needed internet endpoints, see Frequently asked questions for Delivery Optimization. 优化可用于所有 Windows 更新。Optimization can be used for all Windows updates. 有关详细信息,请参阅优化 Windows 10 更新传递For more information, see optimize Windows 10 update delivery.

Microsoft 互连缓存Microsoft Connected Cache

你可以在分发点上安装 Microsoft Connected Cache 服务器。You can install a Microsoft Connected Cache server on your distribution points. 通过将此内容缓存在本地,你的客户端可以从传递优化功能中受益,但你可帮助保护 WAN 链接。By caching this content on-premises, your clients can benefit from the Delivery Optimization feature, but you can help to protect WAN links.

备注

从版本 1910 开始,此功能现在称为“Microsoft Connected Cache”。Starting in version 1910, this feature is now called Microsoft Connected Cache. 它旧称为“传递优化网络内缓存”。It was previously known as Delivery Optimization In-Network Cache.

此缓存服务器充当由传递优化下载的内容的按需透明缓存。This cache server acts as an on-demand transparent cache for content downloaded by Delivery Optimization. 使用客户端设置以确保此服务器仅提供给本地 Configuration Manager 边界组的成员。Use client settings to make sure this server is offered only to the members of the local Configuration Manager boundary group.

此缓存独立于 Configuration Manager 分发点内容。This cache is separate from Configuration Manager's distribution point content. 如果选择和分发点角色一样的驱动,它将单独存储内容。If you choose the same drive as the distribution point role, it stores content separately.

有关详细信息,请参阅 Configuration Manager 中的 Microsoft Connected CacheFor more information, see Microsoft Connected Cache in Configuration Manager.

对等缓存Peer cache

客户端对等缓存可帮助管理对远程客户端内容的部署。Client peer cache helps you manage deployment of content to clients in remote locations. 对等缓存是内置 Configuration Manager 解决方案,使客户端能够直接从本地缓存将内容与其他客户端共享。Peer cache is a built-in Configuration Manager solution that enables clients to share content with other clients directly from their local cache.

首先将启用对等缓存的客户端设置部署到集合。First deploy client settings that enable peer cache to a collection. 然后,该集合的成员可充当同一边界组中其他客户端的对等内容源。Then members of that collection can act as a peer content source for other clients in the same boundary group.

客户端对等缓存源可以将内容分成多个部分。Client peer cache sources can divide content into parts. 这些部分最大限度地减少了网络传输,从而降低了 WAN 利用率。These parts minimize the network transfer to reduce WAN utilization. 管理点提供更详细的内容部分跟踪。The management point provides more detailed tracking of the content parts. 它试图消除每个边界组多次下载相同内容的行为。It tries to eliminate more than one download of the same content per boundary group.

有关详细信息,请参阅用于 Configuration Manager 客户端的对等缓存For more information, see Peer cache for Configuration Manager clients.

Windows PE 对等缓存Windows PE peer cache

使用 Configuration Manager 部署新 OS 时,运行任务序列的计算机可以使用 Windows PE 对等缓存。When you deploy a new OS with Configuration Manager, computers that run the task sequence can use Windows PE peer cache. 它们从对等缓存源而不是从分发点下载内容。They download content from a peer cache source instead of from a distribution point. 此行为有助于最大限度减小没有本地分发点的分支机构方案中的 WAN 流量。This behavior helps minimize WAN traffic in branch office scenarios where there's no local distribution point.

有关详细信息,请参阅 Windows PE 对等缓存For more information, see Windows PE peer cache.

Windows LEDBATWindows LEDBAT

Windows 低额外延迟后台传输 (LEDBAT) 是 Windows Server 的一项网络拥塞控制功能,可帮助管理后台网络传输。Windows Low Extra Delay Background Transport (LEDBAT) is a network congestion control feature of Windows Server to help manage background network transfers. 对于在受支持版本的 Windows Server 上运行的分发点,请启用一个选项以帮助调整网络流量。For distribution points running on supported versions of Windows Server, enable an option to help adjust network traffic. 然后,客户端仅在允许的情况下使用网络带宽。Then clients only use network bandwidth when it's available.

有关 Windows LEDBAT 的详细信息,请参阅新建传输改进博客文章。For more information on Windows LEDBAT in general, see the New transport advancements blog post.

有关如何将 Windows LEDBAT 与 Configuration Manager 分发点一起使用的详细信息,在配置分发点的常规设置时,请参阅设置“调整下载速度以使用未使用的网络带宽 (Windows LEDBAT)”。For more information on how to use Windows LEDBAT with Configuration Manager distribution points, see the setting to Adjust the download speed to use the unused network bandwidth (Windows LEDBAT) when you Configure the general settings of a distribution point.

客户端位置Client locations

客户端将访问以下位置中的内容:The following are locations that clients access content from:

  • Intranet (本地):Intranet (on-premises):

    • 分发点可使用 HTTP 或 HTTPS。Distribution points can use HTTP or HTTPs.

    • 仅当本地分发点不可用时,才使用云分发点进行回退。Only use a cloud distribution point for fallback when on-premises distribution points aren't available.

  • InternetInternet:

    • 要求面向 Internet 的分发点接受 HTTPS。Requires internet-facing distribution points to accept HTTPS.

    • 可使用云分发点或云管理网关 (CMG)。Can use a cloud distribution point or cloud management gateway (CMG).

      CMG 还可向客户端提供内容。A CMG can also serve content to clients. 此功能减少了所需的证书和 Azure VM 的成本。This functionality reduces the required certificates and cost of Azure VMs. 有关详细信息,请参阅修改 CMGFor more information, see Modify a CMG.

  • 工作组Workgroup:

    • 要求分发点接受 HTTPS。Requires distribution points to accept HTTPS.

    • 可使用云分发点或 CMG。Can use a cloud distribution point or CMG.

内容源优先级Content source priority

当客户端需要内容时,它会向管理点发出内容位置请求。When a client needs content, it makes a content location request to the management point. 管理点返回对所请求内容有效的源位置列表。The management point returns a list of source locations that are valid for the requested content. 此列表因具体方案、使用的技术、站点设计、边界组和部署设置而异。This list varies depending upon the specific scenario, technologies in use, site design, boundary groups, and deployment settings. 例如,当任务序列运行时,完整的 Configuration Manager 客户端并非始终在运行,因此行为可能会有所不同。For example, when a task sequence runs, the full Configuration Manager client isn't always running, so the behaviors may differ.

以下列表包含 Configuration Manager 客户端可使用的所有可能的内容源位置,按其优先级排序:The following list contains all of the possible content source locations that the Configuration Manager client can use, in the order in which it prioritizes them:

  1. 与客户端位于同一台计算机上的分发点The distribution point on the same computer as the client
  2. 同一网络子网中的对等源A peer source in the same network subnet
  3. 同一网络子网中的分发点A distribution point in the same network subnet
  4. 同一边界组中的对等源A peer source in the same boundary group
  5. 当前边界组中的分发点A distribution point in the current boundary group
  6. 为回退配置的临近边界组中的分发点A distribution point in a neighbor boundary group configured for fallback
  7. 默认站点边界组中的分发点A distribution point in the default site boundary group
  8. Windows 更新云服务The Windows Update cloud service
  9. 面向 Internet 的分发点An internet-facing distribution point
  10. Azure 中的云分发点A cloud distribution point in Azure

传递优化不适用于此源优先级。Delivery Optimization isn't applicable to this source prioritization. 此列表介绍 Configuration Manager 客户端查找内容的方式。This list is how the Configuration Manager client finds content. Windows 更新代理下载内容进行传递优化。The Windows Update Agent downloads content for Delivery Optimization. 如果 Windows 更新代理找不到内容,则 Configuration Manager 客户端使用此列表搜索该内容。If the Windows Update Agent can't find the content, then the Configuration Manager client uses this list to search for it.

仅当为 BranchCache 启用分发点时,BranchCache 才适用于此列表。BranchCache applies to this list only when you enable a distribution point for BranchCache. 例如,如果客户端要选择优先级列表中的选项 #3,则先请求 BranchCache 元数据的分发点。For example, if a client gets to option #3 in the prioritization list, it first asks the distribution point for BranchCache metadata. 支持 BranchCache 的分发点提供 BranchCache 对等机发现的客户端信息。The BranchCache-enabled distribution point is what provides the client information for BranchCache peer discovery. 如果可以,客户端将通过 BranchCache 对等机下载内容。The client will download content from a BranchCache peer if it can. 如果无法通过 BranchCache 下载内容,则会先尝试分发点本身,然后再继续尝试内容源列表。If it can't download the content via BranchCache, it then tries the distribution point itself, before continuing down the list of content sources. 此行为适用于优先级列表中客户端使用支持 BranchCache 的分发点或云分发点的任何点。This behavior applies at any point in the priority list where the client uses a BranchCache-enabled distribution point or cloud distribution point.

边界组选项的配置可以修改此优先级列表的排序顺序。The configuration of boundary group options can modify the sort order of this priority list.

内容库Content library

内容库是 Configuration Manager 中内容的单实例存储。The content library is the single-instance store of content in Configuration Manager. 此库可减少分发内容的总体大小。This library reduces the overall size of content that you distribute.

分发点Distribution points

Configuration Manager 使用分发点存储在客户端计算机上运行软件所需的文件。Configuration Manager uses distribution points to store files that are required for software to run on client computers. 客户端必须至少可访问一个能用于下载所部属内容的文件的分发点。Clients must have access to at least one distribution point from which they can download the files for content that you deploy.

基本(非专用)分发点通常称为标准分发点。The basic (non-specialized) distribution point is commonly referred to as a standard distribution point. 标准分发点有两种变体需要特别注意:There are two variations on the standard distribution point that receive special attention:

  • 拉取分发点:分发点的一种变体,该分发点获取其他分发点(源分发点)中的内容。Pull-distribution point: A variation of a distribution point where the distribution point obtains content from another distribution point (a source distribution point). 此过程与客户端从分发点下载内容的方式类似。This process is similar to how clients download content from distribution points. 在站点服务器必须将内容直接分发给每个分发点时,拉取分发点有助于避免可能出现的网络带宽瓶颈。Pull-distribution points can help you avoid network bandwidth bottlenecks that occur when the site server must directly distribute content to each distribution point. 使用拉取分发点Use a pull-distribution point.

  • 云分发点:在 Microsoft Azure 中安装的分发点的变体。Cloud distribution point: A variation of a distribution point that's installed on Microsoft Azure. 了解如何使用云分发点Learn how to use a cloud distribution point.

标准分发点支持一系列配置和功能:Standard distribution points support a range of configurations and features:

  • 可使用“计划”或“带宽限制”等控件辅助控制此传输 。Use controls such as schedules or bandwidth throttling to help control this transfer.

  • 使用其他选项,包括“预留内容”和“拉取分发点”以最小化和控制网络消耗 。Use other options, including prestaged content, and pull-distribution points to minimize and control network consumption.

  • “BranchCache”、“对等缓存”和“传递优化”是对等技术,用于减少部署内容时使用的网络带宽 。BranchCache, peer cache, and Delivery Optimization are peer-to-peer technologies to reduce the network bandwidth that's used when you deploy content.

  • OS 部署有不同的配置,例如 PXE多播 There are different configurations for OS deployments, such as PXE and Multicast

  • “移动设备”的选项Options for mobile devices

云分发点和拉取分发点支持许多此类配置,但具有特定于各分发点变体的限制。Cloud and pull distribution points support many of these same configurations, but have limitations that are specific to each distribution point variation.

分发点组Distribution point groups

分发点组是指可简化内容分发的分发点的逻辑分组。Distribution point groups are logical groupings of distribution points that can simplify content distribution.

有关详细信息,请参阅管理分发点组For more information, see Manage distribution point groups.

分发点优先级Distribution point priority

分发点优先级值取决于它将以前的部署传输到该分发点所花费的时间。The distribution point priority value is based on how long it took to transfer previous deployments to that distribution point.

  • 此值可自调整。This value is self-tuning. 它设置在每个分发点上,以帮助 Configuration Manager 更快地将内容传输到更多分发点。It's set on each distribution point to help Configuration Manager more quickly transfer content to more distribution points.

  • 同时向多个分发点或分发点组分发内容时,站点会首先将内容发送到优先级最高的服务器。When you distribute content to multiple distributions points at the same time, or to a distribution point group, the site first sends the content to the server with the highest priority. 然后它将相同内容发送到优先级较低的分发点。Then it sends that same content to a distribution point with a lower priority.

  • 分发点优先级不会替代包的分发优先级。Distribution point priority doesn't replace the distribution priority for packages. 包优先级仍然是站点发送不同内容的决定因素。Package priority remains the deciding factor of when the site sends different content.

例如,有一个优先级较高的包。For example, you have a package that has a high package priority. 将其分发到分发点优先级较低的服务器。You distribute it to a server with a low distribution point priority. 此优先级较高的包始终在优先级较低的包之前传输。This high priority package always transfers before a package that has a lower priority. 即使站点将优先级较低的包分发到分发点优先级较高的服务器,包优先级也适用。The package priority applies even if the site distributes lower priority packages to servers with higher distribution point priorities.

包的高优先级确保 Configuration Manager 在发送任何优先级较低的包之前,将该内容分发到分发点。The high priority of the package ensures that Configuration Manager distributes that content to distribution points before it sends any packages with a lower priority.

备注

请求分发点也使用优先级的概念来对其源分发点的序列进行排序。Pull-distribution points also use a concept of priority to order the sequence of their source distribution points.

  • 传输到服务器的内容的分发点优先级不同于拉取分发点使用的优先级。The distribution point priority for content transfers to the server is distinct from the priority that pull-distribution points use. 拉取分发点从源分发点搜索内容时使用其优先级。Pull-distribution points use their priority when they search for content from a source distribution point.
  • 有关详细信息,请参阅使用拉取分发点For more information, see Use a pull-distribution point.

回退Fallback

在 Configuration Manager Current Branch 中,客户端找到包含内容的分发点的方式发生了诸多变化,其中包括回退。Several things have changed with Configuration Manager current branch in the way that clients find a distribution point that has content, including fallback.

对于无法从与其当前边界组关联的分发点找到内容的客户端,可进行回退,使用与临近边界组关联的内容源位置。Clients that can't find content from a distribution point that's associated with their current boundary group fall back to use content source locations associated with neighbor boundary groups. 若要实现回退,临近边界组与客户端的当前边界组必须存在定义的关系。To be used for fallback, a neighbor boundary group must have a defined relationship with the client's current boundary group. 此关系包含配置的时间,此时间后,无法在本地找到内容的客户端才可在搜索中包含来自临近边界组的内容源。This relationship includes a configured time that must pass before a client that can't find content locally includes content sources from the neighbor boundary group as part of its search.

不再使用首选分发点概念,且无法再使用或执行“允许回退内容源位置”设置。The concepts of preferred distribution points are no longer used, and settings for Allow fallback source locations for content are no longer available or enforced.

有关详细信息,请参阅边界组For more information, see Boundary groups.

网络带宽Network bandwidth

可使用以下选项,帮助管理分发内容时所用的网络带宽量:To help manage the amount of network bandwidth that's used when you distribute content, you can use the following options:

  • 预留内容:将内容传输到分发点,而不通过网络分发内容。Prestaged content: Transferring content to a distribution point without distributing the content across the network.

  • 计划和限制:此配置有助于控制将内容分发到分发点的时间和方式。Scheduling and throttling: Configurations that help you control when and how content is distributed to distribution points.

有关详细信息,请参阅管理网络带宽For more information, see Manage network bandwidth.

到内容源的网络连接速度Network connection speed to content source

在 Configuration Manager Current Branch 中,客户端查找带内容的分发点的方式已发生诸多变化。Several things have changed with Configuration Manager current branch in the way that clients find a distribution point that has content. 这些更改包括到内容源的网络速度。These changes include the network speed to a content source.

不再使用将分发点定义为“快”或“慢”的网络连接速度。Network connection speeds that define a distribution point as Fast or Slow are no longer used. 相反,与边界组关联的各站点系统都被视为相同的系统。Instead, each site system that's associated with a boundary group is treated the same.

有关详细信息,请参阅边界组For more information, see Boundary groups.

按需内容分发On-demand content distribution

按需内容分发是个别应用程序和包部署的选项。On-demand content distribution is an option for individual application and package deployments. 此选项可将内容按需分发到首选服务器。This option enables on-demand content distribution to preferred servers.

  • 要为部署启用此设置,请启用以下选项:将此包的内容分发到首选分发点。To enable this setting for a deployment, enable: Distribute the content for this package to preferred distribution points.

  • 为部署启用此选项后,如果客户端请求该内容而该内容在任何客户端首选分发点上都不可用,Configuration Manager 会将该内容自动分发到客户端首选分发点。When you enable this option for a deployment, and a client requests that content but the content isn't available on any of the client's preferred distribution points, Configuration Manager automatically distributes that content to the client's preferred distribution points.

  • 尽管这会触发 Configuration Manager 将内容自动分发到客户端首选分发点,但客户端仍可在首选分发点接收到部署之前从其他分发点获取该内容。Although this triggers Configuration Manager to automatically distribute the content to that client's preferred distribution points, the client might obtain that content from other distribution points before the preferred distribution points for the client receive the deployment. 若出现该行为,该内容将在该分发点上显示,供搜寻该部署的下一个客户端使用。When this behavior occurs, the content will then be present on that distribution point for use by the next client that seeks that deployment.

有关详细信息,请参阅边界组For more information, see Boundary groups.

包传输管理器Package transfer manager

包传输管理器是一个站点服务器组件,该组件可将内容传输到其他计算机上的分发点。Package transfer manager is the site server component that transfers content to distribution points on other computers.

有关详细信息,请参阅包传输管理器For more information, see Package transfer manager.

预留内容Prestage content

预留内容是将内容传输到分发点,而不通过网络分发内容的过程。Prestaging content is a process of transferring content to a distribution point without distributing the content across the network.

有关详细信息,请参阅管理网络带宽For more information, see Manage network bandwidth.
