Scenarios

To ensure normal network communications between regions in the same geographic region or across geographic regions, you need to purchase a bandwidth package and bind it to a cloud connection. By default, the system allocates 10 kbit/s of bandwidth for testing network connectivity across regions.

• A cloud connection can only have one bandwidth package regardless of if the cloud connection is used for communications within a geographic region or between geographic regions. For example, cloud connection A can only have one bandwidth package between the Chinese mainland and Asia Pacific.
• A bandwidth package can only be bound to one cloud connection.

Procedure

Buy a bandwidth package.

1. Log in to the management console.
2. Hover on the upper left corner to display Service List and choose Networking > Cloud Connect.
3. In the navigation pane on the left, choose Cloud Connect > Bandwidth Packages.
4. Click Buy Bandwidth Package.
5. Configure the parameters based on Table 1 and click Buy Now.

   Table 1 Parameter description

   Parameter	Description	Example Value
   Billing Mode	Specifies how you want the bandwidth package to be billed. Currently, only Yearly/Monthly is available.	Yearly/Monthly
   Name	Specifies the bandwidth package name. The name can contain 1 to 64 characters, including letters, digits, underscores (_), hyphens (-), and periods (.).	daikuaibao1
   Billed By	Specifies by what you want the bandwidth package to be billed.	Bandwidth
   Applicability	Specifies whether you want to use the bandwidth package for network communications within a geographic region or between geographic regions. Two options are available: Single Geographic Region: The regions you assign inter-region bandwidths to are in the same geographic region. Across Geographic Regions: The regions you assign inter-region bandwidths to are in different geographic regions.	Single Geographic Region
   Geographic Region	Specifies the geographic region where regions requiring inter-region bandwidths are located.	Chinese mainland
   Bandwidth	Specifies the bandwidth you require for network communications across regions, in Mbit/s. The sum of all inter-region bandwidths you assign cannot exceed the bandwidth of the bandwidth package. Assign the bandwidth based on your network plan.	50 Mbit/s
   Required Duration	Specifies how long you require the bandwidth package for. Auto renewal is supported.	1 month
   Enterprise Project	Provides a cloud resource management mode, in which cloud resources and members are centrally managed by project.	default
   Cloud Connection	Specifies the cloud connection you want to bind the bandwidth package to. Two options are available, Bind now and Bind later.	Bind now

6. Confirm the information and click Pay Now.
7. Click Pay.

   Go back to the bandwidth package list and locate the bandwidth package. If its status changes to Normal, you can bind the bandwidth package to the cloud connection.

Bind the bandwidth package to the cloud connection.

Bind the purchased bandwidth package to the cloud connection created in step 2.

1. Log in to the management console.
2. Hover on the upper left corner to display Service List and choose Networking > Cloud Connect.
3. In the cloud connection list, click the name of the cloud connection.
4. Click Bound Bandwidth Packages and then click Bind Bandwidth Package.
5. Select the purchased bandwidth package and bind it to the cloud connection.
