Assigning an Inter-Region Bandwidth

Scenarios

If network instances are in the same region, they can communicate with each other by default after they are loaded to one cloud connection. If network instances are in different regions, you need to assign inter-region bandwidths to ensure normal communication between the instances. By default, a cloud connection provides 10 kbit/s of bandwidth for testing cross-region network connectivity.

Constraints

To provide cross-region communication, 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 communication, read and agree to the Cloud Connect Service Disclaimer.

Procedure

1. Go to the Cloud Connections page.
2. Click the name of the cloud connection to go to the Basic Information page.
3. Click the Inter-Region Bandwidths tab.
4. Click Assign Inter-Region Bandwidth and configure the parameters based on Table 1.

   Table 1 Parameters required for assigning inter-region bandwidth

   Parameter	Description
   Regions	Specifies the regions of the network instances that need to communicate with each other. Select two regions.
   Bandwidth Package	Specifies the purchased bandwidth package that will be bound to the cloud connection.
   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. Plan the bandwidth in advance.

5. Click OK.

   Now the network instances in the two regions can communicate with each other.

   

   The default security group rules deny all the inbound traffic. Ensure that security group rules in both directions are correctly configured for resources in the regions to ensure normal communication.
