Buying a Bandwidth Package

Scenarios

To enable 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.

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

To allow you to test network connectivity between regions, Cloud Connect provides 10 kbit/s by default. To test network connectivity, you can ping an ECS in one VPC from an ECS in the other VPC.

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.

Constraints

To provide cross-region network communications, Cloud Connect will obtain and transmit your credential and account ID from the Chinese mainland to the country or region where the network instances you want to connect to are running for identity verification and authentication.

The credential and account ID is required only for providing services for you. If you need to use Cloud Connect for network communications, please read and agree to the Cloud Connect Service Disclaimer.

   Table 1 Parameters for buying a bandwidth package

   Parameter	Description
   Billing Mode	The only option is Yearly/Monthly. You can purchase it by year or month as needed.
   Name	Specifies the bandwidth package name. The name can contain 1 to 64 characters. Only digits, letters, underscores (_), hyphens (-), and periods (.) are allowed.
   Billed By	Specifies by what you want the bandwidth package to be billed.
   Applicability	Specifies whether you want to use the bandwidth package for network communications 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.
   Geographic Region	Specifies the geographic region(s).
   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 total bandwidth of the bandwidth package. Assign the bandwidth based on your network plan. Unit: Mbit/s
   Tag	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.
   Required Duration	Specifies how long you require the bandwidth package for. Auto renewal is supported.
   Cloud Connection	Specifies the cloud connection that you want to bind the bandwidth package to. There are two options: Bind now Bind later

   Table 2 Tag naming requirements

   Parameter	Requirements
   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.
   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.
