f the 802.1Q series of standards focusing initially on the use of Ethernet as a transport mechanism in industrial, time-sensitive environment. Being Ethernet-based, it is a Layer-2 technology. It uses a centralized scheduling scheme to coordinate scheduling and ensure deterministic, low latency. TSN is the new standard for real-time networking. Building on TSN work, a recent (2018) contribution based on joint CPRI and IEEE stan- dardization work is the 802.1CM standard that defines a "TSN for fronthaul" profile that maps to the use of Ethernet in the fronthaul (5G) network. This standard supports the vari- ous fronthaul splits and defines timing (latency) requirements that match to 3GPP/O-RAN standards. We will discuss this standard in more detail elsewhere in this document. Like many other components network management in 3GPP has been traditionally imple- mented using proprietary operations support systems and protocols. These protocols need to be mapped to more open, cloud-based, and dynamically changing environments, calling out for standardization of DU and RU operational control (orchestration) standards. The NETCONF protocol, using the YANG modeling language, are traditionally used for this pur- pose in wireline (router, switch) remote management and control, allowing operators to move from command line interface to API-based control-and with that, automation. These APIs provide abstraction between the DU/RU implementation and its operation and are key to interoperability between RAN components in a multivendor environment. Given the use of YANG in wireline packet orchestration, this network control is a very natural way to allow a natural extension to the wireless world. Integrated small cell Referenced in O-RAN WG7 as the "Integrated gNB-DU," this is a platform that where all functionalities of an O-RAN DU (O-DU) and an O-RAN RU (O-RU) are performed in the same box. This box adheres roughly to the same functional split and functionality as the ISC discussed earlier, with either a split-1 or split-2 (PDCP
