ExpressRoute Direct 线路ExpressRoute Direct circuits

使用 Microsoft Azure 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。Microsoft Azure 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 Microsoft 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 Microsoft 365.

每个对等互连位置都可以访问 Microsoft 的全球网络,可以默认访问地缘政治区域中的任何区域,还可以访问使用高级线路的所有全球区域。Each peering location has access to Microsoft’s global network and can access any region in a geopolitical zone by default and can access all global regions with a premium circuit.

大多数方案中的功能相当于使用 ExpressRoute 服务提供商来运营的线路。The functionality in most scenarios is equivalent to circuits that utilize an ExpressRoute service provider to operate. 若要支持进一步细分以及通过 ExpressRoute Direct 提供的新功能,可以使用 ExpressRoute Direct 线路上存在的某些关键功能。To support further granularity and new capabilities offered using ExpressRoute Direct, there are certain key capabilities that exist on ExpressRoute Direct Circuits.

线路 SKUCircuit SKUs

ExpressRoute Direct 支持将数据大规模引入到 Azure 存储和其他大数据服务中的方案。ExpressRoute Direct supports massive data ingestion scenarios into Azure storage and other big data services. 100 Gbps ExpressRoute Direct 上的 ExpressRoute 线路现在也支持 40 Gbps 和 100 Gbps 线路 SKU 。ExpressRoute circuits on 100 Gbps ExpressRoute Direct now also support 40 Gbps and 100 Gbps circuit SKUs. 物理端口对为 100 或 10 Gbps,可以有多个虚拟线路。The physical port pairs are 100 or 10 Gbps only and can have multiple virtual circuits. 线路大小:Circuit sizes:

VLAN 标记VLAN Tagging

ExpressRoute Direct 同时支持 QinQ 和 Dot1Q VLAN 标记。ExpressRoute Direct supports both QinQ and Dot1Q VLAN tagging.

  • QinQ VLAN 标记 允许基于单个 ExpressRoute 线路的隔离路由域。QinQ VLAN Tagging allows for isolated routing domains on a per ExpressRoute circuit basis. Azure 在创建线路时动态分配一个不能更改的 S-Tag。Azure dynamically allocates an S-Tag at circuit creation and cannot be changed. 线路上的每个对等互连(专用对等互连和 Microsoft 对等互连)都会使用唯一的 C-Tag 作为 VLAN。Each peering on the circuit (Private and Microsoft) will utilize a unique C-Tag as the VLAN. C-Tag 不需要在 ExpressRoute Direct 端口的所有线路上独一无二。The C-Tag is not required to be unique across circuits on the ExpressRoute Direct ports.

  • Dot1Q VLAN 标记 允许基于单个 ExpressRoute Direct 端口对的单个标记 VLAN。Dot1Q VLAN Tagging allows for a single tagged VLAN on a per ExpressRoute Direct port pair basis. 在对等互连上使用的 C-Tag 必须在 ExpressRoute Direct 端口对的所有线路和对等互连中独一无二。A C-Tag used on a peering must be unique across all circuits and peerings on the ExpressRoute Direct port pair.




ExpressRoute Direct 提供相同的企业级 SLA,并且可以通过主动/主动冗余连接连接到 Microsoft 全球网络中。ExpressRoute Direct provides the same enterprise-grade SLA with Active/Active redundant connections into the Microsoft Global Network. ExpressRoute 基础设施是冗余的,连接到 Microsoft 全球网络的功能也是冗余的,并且具有多样性,可以根据客户需求进行相应的缩放。ExpressRoute infrastructure is redundant and connectivity into the Microsoft Global Network is redundant and diverse and scales accordingly with customer requirements.
