Network Planning
Overview
You can connect your on-premises data center to the cloud using a standard or hosted connection:
- Standard connection
A standard connection provides a dedicated port for your exclusive use. You can create standard connections on the console and create multiple connections terminating at different locations as backups for each other to improve reliability. If, for some reason, there is only one carrier, you can create redundancy by configuring different routes for your connections.
Figure 1 Accessing the cloud using standard connections - Hosted connection
If you use a hosted connection to access the cloud, the port you use is shared.
After the partner connects to your on-premises data center and Huawei Cloud, the partner provisions a connection for you.

Network Requirements
- Your on-premises network must use a single-mode fiber with a 1GE, 10GE, 40GE, or 100GE optical module to connect to the access device in the cloud. In addition, key parameters such as the LC, wavelength, and distance must be aligned with the location. Examples of optical module parameters: 1 GE, LC single-mode, 1,310 nm, and 10 km
- Auto-negotiation for the port must be disabled. Port speed and full-duplex mode must be manually configured.
- 802.1Q VLAN encapsulation must be supported on the entire connection, including intermediate devices.
- Your device must support Border Gateway Protocol (BGP) and BGP MD5 authentication or static routing.
- (Optional) You can configure Bidirectional Forwarding Detection (BFD) on the network.
- The maximum transmission unit (MTU) supported at the physical layer cannot exceed 1,522 bytes (14-byte Ethernet header + 4-byte VLAN tag + 1,500-byte IP datagram + 4-byte frame check sequence). The recommended value is 1500.
- Private IP addresses are recommended both on and off the cloud, and the IP address ranges used for communications cannot overlap.
