Assigning a Shared Bandwidth

Scenarios

When you host a large number of applications on the cloud, if each EIP uses a dedicated bandwidth, a lot of bandwidths are required, which incurs high costs. If all EIPs share the same bandwidth, your network operation costs will be lowered and your system O&M as well as resource statistics will be simplified.

Assign a shared bandwidth for use with EIPs.

Procedure

1. Go to the Buy Shared Bandwidth page.
2. Set the parameters as prompted.

   Table 1 Description

   Module	Parameter	Description	Example Value
   Basic Configuration	Region	Regions are geographic areas that are physically isolated from each other. The networks inside different regions are not connected to each other, so resources cannot be shared across different regions. For lower network latency and faster access to your resources, select the region nearest you.	CN-Hong Kong
   Basic Configuration	Billing Mode	A shared bandwidth can be billed on a yearly/monthly or pay-per-use basis. Yearly/Monthly: You pay for the bandwidth by year or month before using it. No other charges apply during the validity period of the bandwidth. Pay-per-use: You pay for the bandwidth based on the amount of time you use the bandwidth.	Yearly/Monthly
   Basic Configuration	Name	The name of the shared bandwidth.	Bandwidth-001
   Basic Configuration	Enterprise Project	The enterprise project that the EIP belongs to. An enterprise project facilitates project-level management and grouping of cloud resources and users. The name of the default project is default.	default
   Bandwidth Details	Bandwidth Type	Select a type of the shared bandwidth based on your EIP type. Standard: Dynamic BGP and premium BGP EIPs can be added to a shared bandwidth of this type. Premium BGP: Premium BGP EIPs can be added to a shared bandwidth of this type. NOTE: In the CN-Hong Kong region, only dynamic BGP EIPs can be added to standard shared bandwidths.	Standard
   Bandwidth Details	Billed By	The billing method for the shared bandwidth. You can specify a shared bandwidth to be billed by bandwidth.	Bandwidth
   Bandwidth Details	Bandwidth (Mbit/s)	The bandwidth size in Mbit/s. The minimum value is 5 Mbit/s.	10
   Bandwidth Details	QoS	After QoS is enabled, you can configure the bandwidth limits for each EIP that uses the shared bandwidth. This makes sure each EIP gets enough bandwidth and uses it better. Configuring bandwidth limits for EIPs is free of charge. For details, see QoS.	N/A
   Required Duration	Required Duration	The duration for which the purchased EIP will use. The duration must be specified if the Billing Mode is set to Yearly/Monthly.	2 months
   Required Duration	Auto-renew	Whether to select Auto-renew. You can select it if the Billing Mode is set to Yearly/Monthly. The auto-renewal period is determined by the required duration. Monthly subscription: The subscription is renewed every month. Yearly subscription: The subscription is renewed each year.	N/A

3. Click Next.
4. Confirm the configurations.
   • If you set Billing Mode to Pay-per-Use, click Submit.
   • If you set Billing Mode to Yearly/Monthly, click Pay Now.

     On the payment page, confirm the order information and click Confirm.

Related Operations

• Adding EIPs to or Removing EIPs from a Shared Bandwidth: After a shared bandwidth is assigned, you can add multiple pay-per-use EIPs to it so that all EIPs share the same bandwidth.
• Modifying a Shared Bandwidth: You can change the size of the shared bandwidth you have assigned.
