ExpressRoute 概述ExpressRoute overview

使用 ExpressRoute 可通过连接服务提供商所提供的专用连接,将本地网络扩展到 Microsoft 云。ExpressRoute lets you extend your on-premises networks into the Microsoft cloud over a private connection facilitated by a connectivity provider. 使用 ExpressRoute 可与 Microsoft Azure 和 Office 365 等 Microsoft 云服务建立连接。With ExpressRoute, you can establish connections to Microsoft cloud services, such as Microsoft Azure and Office 365.

可以从任意位置之间的 (IP VPN) 网络、点到点以太网或在共置设施上通过连接服务提供商的虚拟交叉连接来建立这种连接。Connectivity can be from an any-to-any (IP VPN) network, a point-to-point Ethernet network, or a virtual cross-connection through a connectivity provider at a co-location facility. ExpressRoute 连接不通过公共 Internet 。ExpressRoute connections do not go over the public Internet. 与通过 Internet 的典型连接相比,ExpressRoute 连接提供更高的可靠性、更快的速度、一致的延迟和更高的安全性。This allows ExpressRoute connections to offer more reliability, faster speeds, consistent latencies, and higher security than typical connections over the Internet. 要了解如何使用 ExpressRoute 将网络连接到 Microsoft,请参阅 ExpressRoute 连接模型For information on how to connect your network to Microsoft using ExpressRoute, see ExpressRoute connectivity models.

功能Features

第 3 层连接Layer 3 connectivity

Microsoft 使用 BGP(一种行业标准动态路由协议),在本地网络、Azure 中的实例和 Microsoft 公共地址之间交换路由。Microsoft uses BGP, an industry standard dynamic routing protocol, to exchange routes between your on-premises network, your instances in Azure, and Microsoft public addresses. 我们根据不同的流量配置文件来与网络建立多个 BGP 会话。We establish multiple BGP sessions with your network for different traffic profiles. 有关详细信息,请参阅 ExpressRoute 线路和路由域 一文。More details can be found in the ExpressRoute circuit and routing domains article.

冗余Redundancy

每个 ExpressRoute 线路有两道连接,用于从连接服务提供商/网络边缘连接到两个 Microsoft 企业边缘路由器 (MSEE)。Each ExpressRoute circuit consists of two connections to two Microsoft Enterprise edge routers (MSEEs) from the connectivity provider/your network edge. Microsoft 要求通过连接服务提供商/网络边缘建立双重 BGP 连接 – 各自连接到每个 MSEE。Microsoft requires dual BGP connection from the connectivity provider/your network edge – one to each MSEE. 可以选择不要在一端部署冗余设备/以太网路线。You may choose not to deploy redundant devices/Ethernet circuits at your end. 但是,连接服务提供商会使用冗余设备,确保以冗余方式将连接移交给 Microsoft。However, connectivity providers use redundant devices to ensure that your connections are handed off to Microsoft in a redundant manner. 冗余的第 3 层连接配置是 Microsoft SLA 生效的条件。A redundant Layer 3 connectivity configuration is a requirement for our SLA to be valid.

与 Microsoft 云服务建立连接Connectivity to Microsoft cloud services

通过 ExpressRoute 连接可访问以下服务:ExpressRoute connections enable access to the following services:

  • Microsoft Azure 服务Microsoft Azure services
  • Microsoft Office 365 服务Microsoft Office 365 services

备注

创建 Office 365 是为了通过 Internet 安全可靠地访问。Office 365 was created to be accessed securely and reliably via the Internet. 因此,我们建议将 ExpressRoute 用于特定方案。Because of this, we recommend ExpressRoute for specific scenarios. 有关使用 ExpressRoute 访问 Office 365 的信息,请访问适用于 Office 365 的 Azure ExpressRouteFor information about using ExpressRoute to access Office 365, visit Azure ExpressRoute for Office 365.

有关通过 ExpressRoute 支持的服务的详细列表,请访问 ExpressRoute 常见问题解答页。For a detailed list of services supported over ExpressRoute, visit the ExpressRoute FAQ page.

与地缘政治区域中的所有区域建立连接Connectivity to all regions within a geopolitical region

可以在我们的某个对等位置连接到 Microsoft,并访问该地缘政治区域中的区域。You can connect to Microsoft in one of our peering locations and access regions within the geopolitical region.

例如,如果在阿姆斯特丹通过 ExpressRoute 连接到 Microsoft,则能访问在北欧和西欧托管的所有 Microsoft 云服务。For example, if you connect to Microsoft in Amsterdam through ExpressRoute, you'll have access to all Microsoft cloud services hosted in Northern and Western Europe. 有关地缘政治区域、关联的 Microsoft 云区域和对应的 ExpressRoute 对等位置的概述,请参阅 ExpressRoute 合作伙伴和对等位置一文。For an overview of the geopolitical regions, the associated Microsoft cloud regions, and corresponding ExpressRoute peering locations, see the ExpressRoute partners and peering locations article.

使用 ExpressRoute 高级版建立全球连接Global connectivity with ExpressRoute Premium

你可以启用 ExpressRoute 高级版,将连接扩展为跨越地缘政治边界。You can enable ExpressRoute Premium to extend connectivity across geopolitical boundaries. 例如,如果在阿姆斯特丹通过 ExpressRoute 连接到 Microsoft,则能访问全球所有区域托管的所有 Microsoft 云服务(不包括国家/地区云)。For example, if you connect to Microsoft in Amsterdam through ExpressRoute, you will have access to all Microsoft cloud services hosted in all regions across the world (national clouds are excluded). 就像访问北欧和西欧区域一样,还可以访问部署在南美洲或澳大利亚的服务。You can access services deployed in South America or Australia the same way you access North and West Europe regions.

使用 ExpressRoute Local 建立本地连接Local connectivity with ExpressRoute Local

如果你可以将你的数据带到靠近所需 Azure区域的 ExpressRoute 位置,则可以通过启用本地 SKU 来经济高效地传输数据。You can transfer data cost-effectively by enabling the Local SKU if you can bring your data to an ExpressRoute location near your desired Azure region. 使用 ExpressRoute Local 时,ExpressRoute 端口费用中包括了数据传输。With Local, Data transfer is included in the ExpressRoute port charge.

使用 ExpressRoute Global Reach 进行本地连接Across on-premises connectivity with ExpressRoute Global Reach

可以启用 ExpressRoute Global Reach,通过连接 ExpressRoute 线路,经本地站点交换数据。You can enable ExpressRoute Global Reach to exchange data across your on-premises sites by connecting your ExpressRoute circuits. 例如,如果使用 ExpressRoute Global Reach,位于加利福利亚州的专用数据中心连接到硅谷中的 ExpressRoute,而位于德克萨斯州的另一个专用数据中心连接到达拉斯州的 ExpressRoute,则可以通过两个 ExpressRoute 线路将专用数据中心连接起来。For example, if you have a private data center in California connected to ExpressRoute in Silicon Valley, and another private data center in Texas connected to ExpressRoute in Dallas, with ExpressRoute Global Reach, you can connect your private data centers together through two ExpressRoute circuits. 跨数据中心的流量将通过 Microsoft 的网络进行遍历。Your cross-data-center traffic will traverse through Microsoft's network.
