Running Cellular Network Infrastructure on Linux
Traditionally, much unlike the Ethernet/IP network, classic telecom
infrastructure has been running proprietary hardware, operating systems
and protocol stacks.
In recent years, some Free Software projects have set out to implement
some of the related protocol stacks and network elements on top of
Linux, including the unrelated OpenBTS and OpenBSC projects, as well as
the less known other members of the Osmocom umbrella project: OsmoBSC,
OsmoNITB, OsmoBTS, OsmoPCU, OsmoSGSN, OpenGGSN, and many more.
As signalling protocols tend to be complex and in many use cases the
signalling performance is not super critical, those projects primarily
implement the protocol stacks and network interfaces in user-space.
This presentation will cover an overview of the many different projects
out there, which of the cellular network elements they implement.
