-The XRAN library provides support for transporting In-band and

+The O-RAN library provides support for transporting In-band and
+Quadrature (IQ) samples between the O-DU and O-RU within the O-RAN
architecture based on functional split 7.2x. The library defines the
-xRAN packet formats to be used to transport radio samples within Front
-Haul according to the ORAN Fronthaul specification. It provides
-functionality for generating xRAN packets, appending IQ samples in the
-packet payload, and extracting IQ samples from xRAN packets.

-Note: The Bronze release version of the library supports U-plane and C-plane only. It is ready to be used in the PTP synchronized environment.

C1 and C3 of the connection between O-DU and O-RU are the only
-configurations supported in this release of the xRAN implementation.

only the O-DU side of requirements and provide the “best-effort” PTP primary for

functionality.
VLAN tag functionality is offloaded to NIC as per the configuration of
-VF (refer to Appendix Appendix 1).
+VF (refer to Setup Configuration).
The transport header is defined in the ORAN Fronthaul specification
based on the eCPRI specification.
Only ECPRI_IQ_DATA = 0x00 and ECPRI_RT_CONTROL_DATA= 0x02 message types
are supported.
+For one-way delay measurements the eCPRI Header Field Definitions are
+the same as above until the ecpriPayload. The one-delay measurement
+message format is shown in the next figure.

+.. image:: images/ecpri-one-way-delay-measurement-message.jpg
+ :width: 600
+ :alt: Figure 13. ecpri one-way delay measurement message
+
+Figure 13. ecpri one-way delay measurement message
+
+In addition, for the eCPRI one-delay measurement message there is a
+requirement of dummy bytes insertion so the overall ethernet frame has
+at least 64 bytes.
+
+The measurement ID is a one-byte value used by the sender of the request
+to distinguish the response received between different measurements.
+
+The action type is a one-byte value defined in Table 8 of the eCPRI
+Specification V2.0.
+
+Action Type 0x00 corresponds to a Request
+
+Action Type 0x01 corresponds to a Request with Follow Up
+
+Both values are used by an eCPRI node to initiate a one-way delay
+measurement in the direction of its own node to another node.
+
+Action Type 0x02 corresponds to a Response
+
+Action Type 0x03 is a Remote Request
+
+Action Type 0x04 is a Remote Request with Follow Up
+
+Values 0x03 and 0x04 are used when an eCPRI node needs to know the
+one-way delay from another node to itself.
+
+Action Type 0x05 is the Follow_Up message.
+
+The timestamp uses the IEEE-1588 Timestamp format with 8 bytes for the
+seconds part and 4 bytes for the nanoseconds part. The timestamp is a
+positive time with respect to the epoch.
+
+The compensation value is used with Action Types 0x00 (Request), 0x02
+(Response) or 0x05 (Follow_up) for all others this field contains zeros.
+This value is the compensation time measured in nanoseconds and
+multiplied by 2\ :sup:16 and follows the format for the
+correctionField in the common message header specified by the IEE
+1588-2008 clause 13.3.
+
Handling of ecpriRtcid/ecpriPcid Bit field size is configurable and can
