P802.1CM – Time-Sensitive Networking for Fronthaul

This standard defines profiles that select features, options, configurations, defaults, protocols and procedures of bridges, stations and LANs that are necessary to build networks that are capable of transporting fronthaul streams, which are time sensitive.

The purpose of this standard is to enable the transport of time sensitive fronthaul streams in Ethernet bridged networks.

A mobile operator’s radio equipment and radio equipment controller are often separated and the connection between them has very stringent requirements. This fronthaul connection is not provided by a bridged network today. In an IEEE 802.1 bridged network potentially carrying other categories of traffic, specific configurations of various IEEE 802 standards are needed to meet the requirements of the fronthaul streams. Therefore, the use and the configurations of functions defined in the IEEE 802 standards have to be specified by standard profiles for bridged fronthaul networks.

The P802.1CM project has been finished and produced IEEE Std 802.1CM-2018.
