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/)
*[Network Repository Function (NRF)](https://gitlab.eurecom.fr/oai/cn5g/oai-cn5g-nrf/)
*[Network Repository Function (NRF)](https://gitlab.eurecom.fr/oai/cn5g/oai-cn5g-nrf/)
*[Authentication Server Function (AUSF)](https://gitlab.eurecom.fr/oai/cn5g/oai-cn5g-ausf/)
*[Unified Data Management (UDM)](https://gitlab.eurecom.fr/oai/cn5g/oai-cn5g-udm/)
*[Unified Data Repository (UDR)](https://gitlab.eurecom.fr/oai/cn5g/oai-cn5g-udr/)

OAI-CN5G VPP-UPF, as a part of OAI-CN 5G, is an 3GPP-compliant implementation of the Access and Mobility Management Function (AMF).
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.
The following wiki pages are for the VPP-UPF component of the OAI-CN project.
*[VPP-UPF Installation](Installation)
*[An Example for VPP-UPF Configuration File](amf.conf)
