osmo-uecups - Osmocom UE simulation control/user plane separation
This repository contains a C-language implementation of a simulator for the SGW/MME/UE side of GTP-U. It is part of the Osmocom Open Source Mobile Communications project.
This code is primarily intended to be used in testing of 2G/3G/4G GGSN and P-GW.
Every GTP tunnel (corresponding to a PDP context or EPC bearer) is terminated in a local 'tun' device, which in turn is put into its own network namespace.
This means you can simulate any number of users / sessions / bearers on a single machine without any routing nightmare.
The code only implements the user plane (GTP1U), and not the control plane like GTP1C or GTP2C. osmo-uecups-daemon exposes a JSON-over-SCTP protocol calleD UECUPS, which allows any external control plane instance to add/remove tunnels in the daemon
