Server broadband is divided into uplink broadband and downlink broadband.

Upstream: Upstream traffic flows into the server. Downstream traffic flows out of the server

The scenario is as follows:

Uplink broadband: The content on the server is viewed or downloaded by visitors. For example, when a user visits a website or downloads content from a server to the local area, the uplink broadband is purchased by the user. Downlink broadband: the server itself downloads files to the server. For example: administrator login to the server, using the server to browse the web or download is downlink broadband, generally downlink broadband is free;Copy the code

For example:

We purchased ali Cloud server, whose public network broadband refers to uplink broadband. After we deploy the website on the server, users can access or download the content on the website, which is limited by uplink broadband.

Assuming that we purchase broadband of 1M (uplink broadband), the peak download speed of users is 128KB/ SEC.
