How mirrors work

When using a mirror source, users need to send requests to the mirror source server to obtain the desired software, packages, or files. The mirror source server stores a large amount of data and provides downloads for users. The mirror source searches through the storage for the requested content and transfers the data to the user upon request.

Data transmission process between the client and the mirror source

1. Client initiates a request: Users specify the use of a mirror source in the command line or software and request the desired software or files.
2. DNS resolution: The client resolves the domain name of the mirror source into the corresponding IP address through the Domain Name System (DNS).
3. Connection establishment: The client establishes a TCP connection with the mirror source server.
4. Data transfer: The client sends a request to the mirror source, which returns data to the client based on the request.

Cache mechanism and data update strategy of the mirror source

- Cache mechanism: ***mon caching mechanisms include file caching, memory caching, etc., and different caching strategies can be selected based on requirements.
- Data update strategy: Mirrors need to regularly update data to ensure users obtain the latest software or files. Update strategies can be divided into manual updates and automatic updates, and users can also choose suitable update frequencies based on needs.

By analyzing the working principles of mirror sources, we can better understand their application in software development and the importance of their construction and maintenance process.
