Bandwidth Package Overview

What Is a Bandwidth Package?

A bandwidth package is required for communications between network instances across regions. You can assign inter-region bandwidths from a bandwidth package to enable cross-region communications.

• A bandwidth package is required for inter-region communications regardless of whether:
  • The two regions are within the same geographic region.
  • The two regions are in different geographic regions.
• Bandwidth packages are not required for communications among network instances in the same region.

For details about regions and geographic regions, see Geographic Regions and Huawei Cloud Regions.

Constraints on Bandwidth Packages

• A bandwidth package can only be bound to one cloud connection.
• A cloud connection can only have one bandwidth package bound if the geographic region and billing mode of the bandwidth packages are the same.
• 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.

Bandwidth Package Usage Process

Figure 1 shows the process of using a bandwidth package. A bandwidth package cannot be used independently. You need to bind it to a cloud connection and assign inter-region bandwidths.
