Getting Started with Aether

There are two ways to get started with Aether:

Other Aether guides included on this site include:

Note that Aether was originally deployed as a centrally-manged, ONF-operated cloud service, with the expectation that organizations would participate in Aether by connecting their edge site to this operational deployment.1 That service is now being deprecated in favor of users bringing up their own Aether sites using OnRamp. If you are looking for the original guide describing how to connect a site to Aether, it is still available in Version 2.1 of the Aether Docs. The operational issues described in that guide motivate many of the mechanisms available in the Aether platform today, but now refactored for others to apply to their deployments.


The original Aether service supported the Pronto research project, with edge clusters built on top of an SDN-controlled and fully programmable switching fabric. That fabric is no longer included in Aether OnRamp.

Aether Components

Aether uses components from several ONF projects. Information about these projects can be found at the following sites:

More information about 5G and Aether’s architecture can be found in the Private 5G: A Systems Approach book.
