-The XRAN library provides support for transporting In-band and
-Quadrature (IQ) samples between the O-DU and O-RU within the xRAN
+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.
+O-RAN packet formats to be used to transport radio samples within Front
+Haul according to the O-RAN Fronthaul specification. refer to *Table* 2.
+It provides functionality for generating O-RAN packets, appending IQ samples
+in the packet payload, and extracting IQ samples from O-RAN 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.
+Note: The F release version of the library supports U-plane and C-plane only.
+M-plane is not supported. It is ready to be used in the PTP synchronized environment.
Note: Regarding the clock model and synchronization topology, configurations
C1 and C3 of the connection between O-DU and O-RU are the only
-configurations supported in this release of the xRAN implementation.

Fronthaul requirements as defined for O-RU is out of the scope of this
document. PTP primary and PTP secondary configuration are expected to satisfy
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 *Appendix A, Setup Configuration*).
-The transport header is defined in the ORAN Fronthaul specification
-based on the eCPRI specification.
+The transport header is defined in the O-RAN Fronthaul specification
+based on the eCPRI specification, Refer to *Table 2*.

-Only ECPRI_IQ_DATA = 0x00 and ECPRI_RT_CONTROL_DATA= 0x02 message types
-are supported.
+Only ECPRI_IQ_DATA = 0x00 , ECPRI_RT_CONTROL_DATA= 0x02 and
+ECPRI_DELAY_MEASUREMENT 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.

+ :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

C-plane
-------
C-Plane messages are encapsulated using a two-layered header approach.
The first layer consists of an eCPRI standard header, including
corresponding fields used to indicate the message type, while the second
-layer is an application layer including necessary fields for control and
-synchronization. Within the application layer, a “section” defines the characteristics of U-plane data to be transferred or received from a
-beam with one pattern id. In general, the transport header,application
+layer is an application layer, including necessary fields for control
+and synchronization. Within the application layer, a “section” defines
+the characteristics of U-plane data to be transferred or received from a
+beam with one pattern id. In general, the transport header, application
header, and sections are all intended to be aligned on 4-byte boundaries
and are transmitted in “network byte order” meaning the most significant
byte of a multi-byte parameter is transmitted first.
