This topic describes the inbound and outbound bandwidth of Elastic Compute Service (ECS) instances.
This topic describes the inbound and outbound bandwidth of ECS instances.
When the pay-by-traffic billing method for network usage is used, the maximum inbound and outbound bandwidth values are used as upper limits of bandwidths instead of guaranteed performance specifications. In scenarios where demand outstrips resource supplies, these maximum bandwidth values may not be reached. If you want guaranteed bandwidth for your instance, use the pay-by-bandwidth billing method for network usage.
Bandwidth (Mbit/s) | Description |
Inbound bandwidth | The bandwidth for traffic that flows to an instance. For example, the inbound bandwidth is used to download external network resources from the instance or upload resources to the instance by using an FTP client. The maximum inbound bandwidth is determined by the outbound bandwidth.
|
Outbound bandwidth | The bandwidth for traffic that flows from an instance. For example, the outbound bandwidth is used to provide external access from the instance or download internal resources of the instance by using an FTP client. The outbound bandwidth of an instance is the purchased bandwidth. The outbound bandwidth of an instance is capped at 100 Mbit/s or 200 Mbit/s regardless of whether the instance resides in a virtual private cloud (VPC) or the classic network. The maximum outbound bandwidth varies based on the billing method of the instance. |
