Configuring HTTP Service
During local upgrade, the device serves as the HTTP server and users log in to the device through a Web browser
and upload the files to be upgraded to the device and realize the upgrade.
During remote upgrade, the device serves as the client, connects to the remote HTTP server and acquires the files
on the server to upgrade the local files.
Working Principle
HTTP Working Process
HTTP provides services for Web management. Users can log in to devices through the Web interface for configuration
and management. Web management includes the Web client and server, and the HTTP service can adopt the client or
server mode. The HTTP client is embedded in the Web browser of the Web management client and can send HTTP
packets and receive and process HTTP response packets. The Web server (HTTP server) is embedded in the device.
The information interaction process between the client and server is described as follows:
TCP connection is established between the client and server. The default port number of the HTTP service and
HTTPS service is 80 and 443 respectively.
The client sends a request to the server.
After processing the client's request, the server responds to the client.
After the HTTP service processes a request, the TCP connection between the client and server is cancelled; the
HTTPS can process multiple requests until the client sends a termination request or the connection is cancelled as
the server is overtime.
The process of the remote HTTP upgrade service can be summarized as follows:
Connect to the server. During the connection, prioritize the server address configured by the user. If connection to
the address fails, connect to the server address in the local upgrade record.
Send version numbers of all programs to the server.
After analysis, the server provides a list of files to be downloaded.
The device connects to the file server and downloads necessary files according to the list. Users can connect to
different servers to download different files.
Prepare for file upgrade.
