Scenarios

To enable 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.

To allow you to test network connectivity between regions, the system allocates 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.

Procedure

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 Parameters

   Parameter	Description	Example Value
   Billing Mode	Specifies how you want the bandwidth package to be billed.	Yearly/Monthly
   Name	Specifies the bandwidth package name. The name can contain 1 to 64 characters, including digits, letters, underscores (_), hyphens (-), and periods (.).	daikuaibao1
   Billed By	Specifies by what you want the bandwidth package to be billed. Currently, only Bandwidth is available.	Bandwidth
   Applicability	Specifies whether the bandwidth package is used for 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.	China
   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

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 a cloud connection.
