ExpressRoute 连接模型ExpressRoute connectivity models

在本地网络和 Azure 云之间创建连接时,可以采用三种不同的方式:CloudExchange 归置点到点以太网连接任意位置之间的 (IPVPN) 连接You can create a connection between your on-premises network and the Azure cloud in three different ways, CloudExchange Co-location, Point-to-point Ethernet Connection, and Any-to-any (IPVPN) Connection. 连接服务提供商可以提供一个或多个连接模型。Connectivity providers can offer one or more connectivity models. 可以咨询连接服务提供商来选择最合适的模型。You can work with your connectivity provider to pick the model that works best for you.

共置于云交换位置Co-located at a cloud exchange

如果所在的位置提供云交换设施,则可以订购虚拟交叉连接,以通过共同租用提供商的以太网交换连接到 Azure 云。If you are co-located in a facility with a cloud exchange, you can order virtual cross-connections to the Azure cloud through the co-location provider’s Ethernet exchange. 共同租用提供商可以在共置设施中的基础结构与 Azure 云之间提供第 2 层交叉连接或托管的第 3 层交叉连接。Co-location providers can offer either Layer 2 cross-connections, or managed Layer 3 cross-connections between your infrastructure in the co-location facility and the Azure cloud.

点到点以太网连接Point-to-point Ethernet connections

可以通过点到点以太网链路,将本地数据中心/办公室连接到 Azure 云。You can connect your on-premises datacenters/offices to the Azure cloud through point-to-point Ethernet links. 点到点以太网提供商可以在站点与 Azure 云之间提供第 2 层连接或托管的第 3 层连接。Point-to-point Ethernet providers can offer Layer 2 connections, or managed Layer 3 connections between your site and the Azure cloud.

任意位置之间的 (IPVPN) 网络Any-to-any (IPVPN) networks

可以将 WAN 集成到 Azure 云。You can integrate your WAN with the Azure cloud. IPVPN 提供商(通常为 MPLS VPN)可在分支机构与数据中心之间提供任意位置之间的连接。IPVPN providers (typically MPLS VPN) offer any-to-any connectivity between your branch offices and datacenters. Azure 云可与 WAN 互连,就如同它是其他任何一个分支机构。The Azure cloud can be interconnected to your WAN to make it look just like any other branch office. WAN 提供商通常提供托管的第 3 层连接。WAN providers typically offer managed Layer 3 connectivity. 在上述所有连接模型中,ExpressRoute 功能与特性完全相同。ExpressRoute capabilities and features are all identical across all of the above connectivity models.
