Global Connection Bandwidth Usage Guidelines

Overview

A global connection bandwidth is used by instances to allow communications over the Huawei Cloud backbone network.

Global connection bandwidths can be bound to instances such as global EIPs and cloud connections to allow them to communicate on private networks.

There are different types of global connection bandwidths that are designed for different application scenarios, including multi-city, geographic-region, and cross-geographic-region bandwidths. Geographic-region and cross-geographic-region bandwidths are often bound to cloud connections for communications on the cloud.

Instance Type

Description

Scenario

Multi-city

Global EIPs

Select this type of bandwidth if you need communications between different cities, for example, Shanghai and its surrounding cities.

A global EIP and its associated resource, such as an ECS or load balancer, have to be from the same access point, for example, CN East or CN South.

Geographic-region

Global EIPs

Cloud connection

Select this type of bandwidth if you need communications within a geographic region. Geographic regions include the Chinese mainland, Asia Pacific, and Southern Africa. For example, CN East-Shanghai1 and CN South-Guangzhou are regions in the Chinese mainland. For details about the relationship between geographic regions and Huawei Cloud regions, see Geographic Regions and Huawei Cloud Regions.

Enterprise routers connected by a cloud connection that use a geographic-region bandwidth must from the same geographic region.

Cross-geographic-region

Global EIPs

Cloud connection

Select this type of bandwidth if you need communications across geographic regions. Geographic regions include the Chinese mainland, Asia Pacific, and Southern Africa. For example, CN East-Shanghai1 and CN-Hong Kong are from different geographic regions. For details about the relationship between geographic regions and Huawei Cloud regions, see Geographic Regions and Huawei Cloud Regions.

Enterprise routers connected by a cloud connection that use a cross-geographic-region bandwidth are from different geographic regions.
