What Are Inbound Bandwidth and Outbound Bandwidth?

Bandwidth refers to the maximum amount of data that can be transmitted in a given amount of time (generally one second). A larger bandwidth value indicates a stronger transmission capability. Bandwidth is classified into public bandwidth and private bandwidth.

Public bandwidth is the bandwidth consumed when data is transferred between Huawei Cloud instances and the Internet. Public bandwidth is classified into inbound bandwidth and outbound bandwidth. For details the outbound bandwidth and inbound bandwidth, see Table 1.

Description

Outbound bandwidth

Bandwidth consumed when data is transferred from Huawei Cloud to the Internet. For example, the outbound bandwidth is used when ECSs provide services accessible from the Internet and FTP clients download resources from the ECSs. Outbound bandwidth means the same thing as upstream bandwidth on the Cloud Eye console.

Huawei Cloud only charges for the outbound bandwidth.

NOTE:

Inbound bandwidth

Bandwidth consumed when data is transferred from the Internet to Huawei Cloud. For example, the inbound bandwidth is used when resources are downloaded from the Internet to ECSs and FTP clients upload resources to the ECSs. Inbound bandwidth means the same thing as downstream bandwidth on the Cloud Eye console.

The maximum inbound bandwidth depends on the size of the outbound bandwidth.
  • If your purchased bandwidth is less than or equal to 10 Mbit/s, the inbound bandwidth will be 10 Mbit/s, and the outbound bandwidth will be the same as the purchased bandwidth.
  • If your purchased bandwidth is greater than 10 Mbit/s, the outbound and inbound bandwidth will be the same as the purchased bandwidth.

The preceding bandwidth limit is not applicable in CN North-Beijing1 and CN East-Shanghai2.
