[[OsmoGGSN]] is an implementation of the Gateway GPRS Support Node ("GGSN":http://en.wikipedia.org/wiki/GGSN) element in the GPRS core network.

[[OsmoGGSN]] is developed by Harald Welte, Holger Freyther, Pablo Neira and sysmocom GmbH.  It is baed on the earlier [[OpenGGSN]] which was developed in 2002 to 2004 by Mondru AB and was abandoned for some years before being adopted by the Osmocom project around 2010.
