OsmoGGSN is an Open Source implementation of a GGSN (Gateway GPRS Support Node). It is the successor to OpenGGSN and provides a Gp (GTP v0/v1) interface towards SGSNs like OsmoSGSN and a Gi interface towards the IP network. It supports Linux kernel GTP-U acceleration via a linux-kernel-gtp-u.

Binary Packages

Osmocom provides binary packages for several flavors of Debian and Ubuntu GNU/Linux on a variety of architectures (i586, x86_64, armhf, armv7l). Unless you are a software developer interested in developing on Osmocom, it is recommended you use those packages instead of building from source.

For more details see Binary_Packages
