libgtpnl¶
In order to control the kernel-side GTP-U plane, a netlink based control interface between GTP-C in userspace and GTP-U in kernelspace was invented.
The encoding and decoding of these control messages is implemented in the libgtpnl (library for GTP netlink). The library is available from https://gitea.osmocom.org/cellular-infrastructure/libgtpnl
The library uses GNU autotools, so the usual
autoreconf -fi && ./configure && make && make install
should be used to build + install it.
Command-line tools¶
The tools directory of the repository contains command-line tools gtp-link and gtp-tunnel. See this presentation and this shell script as basic usage examples.
