Network Quality Server


The Network Quality Server project was created as a place to share example servers that can be used by the networkQuality command line tool available in macOS 12.

You can find a textual description of what a server needs to implement here

There’s also 2 complete reference server implementations, one written in Swift and the other in Go. Also provided are configurations for HTTP server/proxy servers: Apache Traffic Server, Apache HTTPD and nginx.

All the samples require an SSL certificate to run.

Using networkQuality against your server

The networkQuality CLI takes a -C switch allowing you to point it at your server.

user@myhost ~ % networkQuality -C
==== SUMMARY ====
Upload capacity: 29.662 Mbps
Download capacity: 541.622 Mbps
Upload flows: 12
Download flows: 12
Responsiveness: High (1825 RPM)

NOTE: The networkQuality CLI tool will only connect to a server presenting a valid SSL certificate. If you are using a custom CA, ensure the CA is trusted by the system.

There are more options available to affect behavior of this utility. See the manpage of networkQuality for more info.
