1. A distributed radio access network (RAN), comprising:
a new radio unit (RU) being connected to a front-haul network and configured to:
determine its own Internet Protocol (IP) address based on its Media Access Control (MAC) address;
send a discovery message to all radio controllers in the front-haul network via a multicast address; and
a plurality of radio controllers communicatively coupled to the new RU via the front-haul network, wherein each of the plurality of radio controllers are configured to receive the discovery message and determine whether the new RU is assigned to the respective radio controller;
wherein each of at least one radio controller, to which the new RU is assigned, establishes at least one configuration session with the new RU.
