ExpressRoute 概欟ExpressRoute overview

ExpressRoute 可讓您透過連線提供者所提供的私人連線,將內部部署網路延伸至 Microsoft 雲端。ExpressRoute lets you extend your on-premises networks into the Microsoft cloud over a private connection facilitated by a connectivity provider. 透過 ExpressRoute,您可以建立 Microsoft 雲端服務的連線,例如 Microsoft Azure、Office 365 和 Dynamics 365。With ExpressRoute, you can establish connections to Microsoft cloud services, such as Microsoft Azure, Office 365, and Dynamics 365.

從任意點對任意點 (IP VPN) 網路、點對點乙太網路,或在共置設施上透過連線提供者的虛擬交叉連接,都可以進行連線。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 連線不會經過公用網際網路。ExpressRoute connections do not go over the public Internet. 相較於一般網際網路連線,這可讓 ExpressRoute 連線提供更高的可靠性、更快的速度、一致的延遲和更高的安全性。This allows ExpressRoute connections to offer more reliability, faster speeds, consistent latencies, and higher security than typical connections over the Internet. 如需如何使用 ExpressRoute 將您的網路連接至 Microsoft 的詳細資訊,請參閱 ExpressRoute 連線模型For information on how to connect your network to Microsoft using ExpressRoute, see ExpressRoute connectivity models.

特性Features

第 3 層連線能力Layer 3 connectivity

Microsoft 採用BGP (業界標準動態路由通訊協定),在您的內部部署網路、Azure 中的執行個體和 Microsoft 公用位址之間交換路由。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. 我們會針對不同的流量設定檔,與您的網路建立多個 BGP 工作階段。We establish multiple BGP sessions with your network for different traffic profiles. 如需詳細資訊,請參閱 ExpressRoute 線路和路由網域 一文。More details can be found in the ExpressRoute circuit and routing domains article.

備援性Redundancy

每個 ExpressRoute 線路有兩條連線,從連線提供者 / 您的網路邊緣連接到兩個 Microsoft Enterprise 邊緣路由器 (MSEE)。Each ExpressRoute circuit consists of two connections to two Microsoft Enterprise edge routers (MSEEs) from the connectivity provider/your network edge. Microsoft 需要有來自連線提供者 / 您網路邊緣的雙重 BGP 連線 – 每個連線皆各自連線至每個 MSEE。Microsoft requires dual BGP connection from the connectivity provider/your network edge – one to each MSEE. 您可以選擇不要在您這端部署備援裝置 / 乙太網路線路。You may choose not to deploy redundant devices/Ethernet circuits at your end. 不過,連線提供者會使用備援裝置,確保以備援方式將您的連線交給 Microsoft。However, connectivity providers use redundant devices to ensure that your connections are handed off to Microsoft in a redundant manner. 備援第 3 層連線組態是我們的 SLA 生效的條件。A redundant Layer 3 connectivity configuration is a requirement for our SLA to be valid.

連線到 Microsoft 雲端服務Connectivity to Microsoft cloud services

透過 ExpressRoute 連線可存取下列服務:ExpressRoute connections enable access to the following services:

  • Microsoft Azure 服務Microsoft Azure services
  • Microsoft Office 365 服務Microsoft Office 365 services
  • Microsoft Dynamics 365Microsoft Dynamics 365

注意

Office 365 原本就設計為可透過網際網路來安全可靠地存取。Office 365 was created to be accessed securely and reliably via the Internet. 因此,在特定案例中,建議使用 ExpressRoute。Because of this, we recommend ExpressRoute for specific scenarios. 如需使用 ExpressRoute 來存取 Office 365 的相關資訊,請造訪 Azure ExpressRoute for Office 365For information about using ExpressRoute to access Office 365, visit Azure ExpressRoute for Office 365.

如需透過 ExpressRoute 所支援的詳細服務清單,請瀏覽 ExpressRoute 常見問題集頁面。For a detailed list of services supported over ExpressRoute, visit the ExpressRoute FAQ page.

連線到地理政治區域內的所有區域Connectivity to all regions within a geopolitical region

您可以在我們的其中一個對等互連位置中連線到 Microsoft,並存取地理政治區域內的區域。You can connect to Microsoft in one of our peering locations and access regions within the geopolitical region.

例如,如果您在阿姆斯特丹透過 ExpressRoute 連線至 Microsoft,您就能夠存取在北歐和西歐託管的所有 Microsoft 雲端服務。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. 如需地理政治地區、相關聯的 Microsoft 雲端區域以及對應的 ExpressRoute 對等互連位置之概觀,請參閱 ExpressRoute 合作夥伴和對等互連位置一文。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.

搭配 ExpressRoute Premium 的全球連線能力Global connectivity with ExpressRoute Premium

您可以啟用 ExpressRoute Premium 來將連線能力延伸到跨越地理政治的界限。You can enable ExpressRoute Premium to extend connectivity across geopolitical boundaries. 例如,如果您在阿姆斯特丹透過 ExpressRoute 連線至 Microsoft,您就能夠存取全球所有區域託管的所有 Microsoft 雲端服務 (不包括國家雲端)。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). 就像存取北歐和西歐區域一樣,您也可以存取部署在南美洲或澳大利亞的服務。You can access services deployed in South America or Australia the same way you access North and West Europe regions.

搭配 ExpressRoute Local 的本地連線能力Local connectivity with ExpressRoute Local

如果您可以將資料移至鄰近您所需 Azure 區域的 ExpressRoute 位置,便可以啟用本地 SKU來以符合成本效益的方式傳送資料。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. 透過使用 Local,資料轉送將會被包含在 ExpressRoute 連接埠費用中。With Local, Data transfer is included in the ExpressRoute port charge.

使用 ExpressRoute Global Reach 跨內部部署連線Across on-premises connectivity with ExpressRoute Global Reach

您可以啟用 ExpressRoute Global Reach 來將 ExpressRoute 線路連線,以在內部部署站台之間交換資料。You can enable ExpressRoute Global Reach to exchange data across your on-premises sites by connecting your ExpressRoute circuits. 例如,如果您有位在加州的私人資料中心連線到位在矽谷的 ExpressRoute,以及另一個位在德州的私人資料中心連線到位在達拉斯的 ExpressRoute,使用 ExpressRoute Global Reach 您就可以透過兩個 ExpressRoute 線路將您的私人資料中心連線在一起。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. 您跨資料中心的流量會透過 Microsoft 的網路周遊。Your cross-data-center traffic will traverse through Microsoft's network.
