libgtpnl - netlink library for Linux kernel GTP

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).

libgtpnl is part of the Osmocom Open Source Mobile Communications project.


The official homepage of the project is
