Buying a Bandwidth Package

Scenarios

To enable normal communication between regions in the same geographic region or different geographic regions, you need to purchase at least one bandwidth package and bind them to a cloud connection.

Bandwidth packages are used when VPCs are loaded to a cloud connection.

Constraints

• No bandwidth packages are required if two VPCs are in the same region because they can communicate with each other by default after they are loaded to the same cloud connection.
• The geographic regions of a bandwidth package cannot be changed after it is purchased.

Buying a Bandwidth Package

1. Go to the Buy Bandwidth Package page.
2. Configure the parameters based on Table 1 and click Next.

   Table 1 Parameters for buying a bandwidth package

   Parameter	Description	Example Value
   Basic Information
   Billing Mode	The only option is Yearly/Monthly. You can purchase it by year or month as needed.	Yearly/Monthly
   Name	Specifies the bandwidth package name. The name can contain 1 to 64 characters. Only digits, letters, underscores (_), hyphens (-), and periods (.) are allowed.	bandwidthPackge-test
   Enterprise Project	Provides a cloud resource management mode, in which cloud resources and members are centrally managed by project.	default
   Tag (Optional)	Identifies the bandwidth package. A tag consists of a key and a value. You can add 20 tags to a bandwidth package. The tag key and value must meet the requirements listed in Table 2. NOTE: If a predefined tag has been created on TMS, you can directly select the corresponding tag key and value. For details about predefined tags, see Predefined Tags.	-
   Bandwidth Details
   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 communication within a geographic region or between geographic regions. There are two options: Single geographic region: Use the bandwidth package between regions in the same geographic region. Across geographic regions: Use the bandwidth package between regions in different geographic regions.	Single geographic region
   Geographic Region	Specifies the geographic regions.	Chinese mainland
   Bandwidth	Specifies the bandwidth you require for communication between regions, in Mbit/s. The sum of all inter-region bandwidths you assign cannot exceed the total bandwidth of the bandwidth package. Assign the bandwidth based on your network plan. Unit: Mbit/s	10
   Required Duration	Specifies how long you require the bandwidth package for. Auto renewal is supported.	1
   Cloud Connection	Specifies the cloud connection you want to bind the bandwidth package to. There are two options: Bind now Bind later	Bind later

   Table 2 Tag naming requirements

   Parameter	Requirements	Example Value
   Tag key	For each resource, each tag key must be unique, and each tag key can only have one tag value. Cannot be left blank. Can contain no more than 128 characters. Can contain letters in any language, digits, spaces, underscores (_), periods (.), colons (:), equal signs (=), plus signs (+), minus signs (-), and at signs (@). Cannot start with _sys_ or a space or end with a space.	bandwidthPackge_key1
   Tag value	Can be left blank. Can contain no more than 255 characters. Can contain letters in any language, digits, spaces, underscores (_), periods (.), colons (:), slashes (/), equal signs (=), plus signs (+), minus signs (-), and at signs (@). Cannot start or end with a space.	bandwidthPackge-01

3. Confirm the configuration and submit your order.

   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.
