Installation

System requirements

The diameter package can be installed from PyPI:

~# pip install python-diameter

The minimum required Python version is 3.11, a fairly recent Linux kernel is recommended. There is no Windows or Mac compatibility.

SCTP

The diameter stack can operate in both TCP and SCTP modes. For connectivity over the SCTP transport, an optional dependency for pysctp must be installed separately:

~# pip install pysctp

Note that installing the pysctp package requires at least an SCTP-aware kernel and possibly additional OS packages installed prior installation. Refer to pysctp installation documentation for further instructions.

There is no need to make diameter package SCTP-aware. If pysctp is available, it will be used automatically for any peer configured to use the SCTP transport protocol.
