What does uplink and downlink bandwidth mean? Server public network bandwidth is divided into two directions, namely uplink bandwidth and downlink bandwidth. From the server's perspective, uplink bandwidth and downlink bandwidth represent user uploading or downloading? For the server, the client's download resources consume It is the upstream traffic of the server. The client uploads resources and consumes the downstream traffic of the server. The server is usually purchased. For example, in Alibaba Cloud, the bandwidth you usually buy refers to the uplink bandwidth, and the downlink bandwidth is usually unlimited. And the calculation of traffic is generally based on the uplink.
Therefore, the client uploading resources has basically no impact on the server's bandwidth, because the server's downlink is basically unlimited and has an impact on the client's own network bandwidth;
The resource downloaded by the client not only has an impact on the bandwidth of the server, but also has an impact on the network bandwidth of the client itself.
Server upstream bandwidth refers to traffic flowing out of the server, and downstream bandwidth refers to traffic flowing into the server. That is, the server's upstream bandwidth corresponds to users downloading files from the server to the local; the server's downstream bandwidth represents the users uploading data from the local to the server.
Therefore, the server upstream bandwidth and downstream bandwidth:
Uplink broadband generally refers to uplink bandwidth, that is, broadband uplink transmission rate. Refers to the user's direction to the telecommunications service provider, such as uploading files.
Downlink broadband generally refers to downlink bandwidth, that is, broadband downlink transmission rate. Refers to the direction from the telecommunications service provider to the user, such as downloading a file.
Are there charges for the cloud server's internal network bandwidth? Are there charges for the upstream bandwidth of the cloud server's public network? Are there charges for the cloud server's downlink bandwidth? Take Alibaba Cloud server bandwidth as an example:
1. The internal network bandwidth of Alibaba Cloud servers is free, and the charges refer to the public network bandwidth and external network bandwidth;
2. Alibaba Cloud public network bandwidth is divided into uplink and downlink, uplink bandwidth is charged, and downlink bandwidth is free;
3. Convert to inbound bandwidth and outbound bandwidth. Alibaba Cloud public network bandwidth is charged for outbound bandwidth, and inbound bandwidth is free.
To sum up, the bandwidth that users spend money to purchase is only the uplink traffic of the public network bandwidth, that is, the outgoing bandwidth of the public network bandwidth.
