OAI-CN 5G is an implementation of the 3GPP specifications for the 5G Core Network. For instance (phase 2), it contains the implementation of the following network elements (Each element implementation has its own repository):
*[Access and Mobility Management Function (AMF)](https://gitlab.eurecom.fr/oai/cn5g/oai-cn5g-amf/)
*[Session Management Function (SMF)](https://gitlab.eurecom.fr/oai/cn5g/oai-cn5g-smf/)
*[User Plane Function (UPF)](https://github.com/OPENAIRINTERFACE/openair-spgwu-tiny/)
*[User Plane Function (VPP-UPF)](https://gitlab.eurecom.fr/oai/cn5g/oai-cn5g-upf-vpp)

OAI-CN5G VPP-UPF, as a part of OAI-CN 5G, is an 3GPP-compliant implementation of the Access and Mobility Management Function (AMF).
OAI-CN5G VPP-UPF, is a based project of (Travelping VPP-UPG)[https://github.com/travelping/upg-vpp]. OAI added following features on top of VPP-UPG -
* NF Registration
* GTPU extension header support
* Traffic steering based on forwarding policy
* Build instruction for docker and podman
This wiki provides information to build and launch VPP-UPF manually in a physical/virtual machine. We highly recommend that you follow the [container-based tutorial](https://gitlab.eurecom.fr/oai/cn5g/oai-cn5g-fed) to have a better tested/supported deployment environment from our team.
