Network Planning

Updated on 2024-06-24 GMT+08:00

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.

Parties involved

You, leased line carrier, equipment room carrier, and Huawei Cloud

You, leased line carrier, and Huawei Cloud

Process

  1. You create a connection on the console to reserve a port.
  2. You contact the leased line carrier and supervise the line deployment from your on-premises data center to the equipment room at the location you choose.
  3. You contact the carrier operating the equipment room at the location you choose to complete the cabling (if required) and connect the jumper inside the equipment room.
  4. Your carrier works with Huawei Cloud to commission access devices.
  5. You complete required network configuration on the console, including creating a virtual gateway and virtual interface.
  1. The partner deploys the leased line from your on-premises data center to the location you select.
  2. The carrier completes the commissioning of access devices.
  3. You complete required network configuration on the console, including creating a virtual gateway and virtual interface.

Pricing

  • Pay for the port (by month or year) to Huawei Cloud.
  • Pay to the carrier of the equipment room at the location for the cabling inside the equipment room.
  • Pay to the carrier of your on-premises data center for the cabling inside the equipment room.
  • Pay to the carrier of the lease line for other work and the bandwidth. For details, see Billing.
  • You do not need to pay for the port to Huawei Cloud.
  • Pay to the carrier of your on-premises data center for the cabling inside the equipment room.
  • Pay to the carrier of the lease line for other work and the bandwidth.

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.
