Yes, dedicated line access supports 802.1Q VLAN encapsulation technology. This allows multiple virtual LANs (VLANs) to be transmitted over a single physical connection by tagging Ethernet frames with VLAN IDs.
For example, in an enterprise network, different departments (e.g., finance, HR, and IT) may require isolated network segments for security and traffic management. By using 802.1Q VLAN encapsulation over a dedicated line, the enterprise can segment traffic without needing separate physical connections. Each VLAN is identified by a unique tag, ensuring data isolation while sharing the same physical infrastructure.
In cloud environments, Tencent Cloud provides dedicated line services that support 802.1Q VLAN tagging, enabling secure and efficient network segmentation for hybrid cloud or multi-region deployments. This is particularly useful for enterprises connecting on-premises data centers to Tencent Cloud virtual private clouds (VPCs) while maintaining VLAN isolation.
