| 15 | Front Haul Interface Library Overview |
| 16 | ===================================== |
| 17 | |
| 18 | The O-RAN FHI Lib is built on top of DPDK to perform U-plane and C-plane functions according to the |
| 19 | ORAN Fronthaul Interface specification between O-DU and O-RU. |
| 20 | S-Plane support requires PTP for Linux version 2.0 or later |
| 21 | The management plane is outside of the scope of this library implementation. |

| 24 | Project Resources |
| 25 | ----------------- |
| 26 | |
| 27 | The source code is available from the Linux Foundation Gerrit server: |
| 28 | `<https://gerrit.o-ran-sc.org/r/a/o-du/phy/fhi_lib/src>`_ |
| 29 | |
| 30 | The build (CI) jobs will be in the Linux Foundation Jenkins server: |
| 31 | |

| 43 | ODULOW |
| 44 | ------ |
| 45 | |
| 46 | The ODULOW uses the FHI library to access the C-Plane and U-Plane interfaces to the O-RU. |
| 47 | The FHI Lib is defined to communicate TTI event, symbol time, C-plane information as well as IQ sample data. |
| 48 | |
| 49 | DPDK |
| 50 | ---- |
| 51 | |
| 52 | DPDK is used by the FHI Library to interface to an Ethernet Port |
| 53 | The FHI Library is built on top of DPDK to perform U-plane and C-plane functions per the ORAN Front Haul specifications |
| 54 | |
| 55 | Linux PTP |
| 56 | --------- |
| 57 | Linux PTP is used to synchronize the system timer to the GPS time |
