Abstract

A method for configuring resources of a radio access network (RAN) including a radio unit includes monitoring, by a data plane node, a quality of at least one portion of a link between the radio unit and a central processing unit of the RAN; determining, by the data plane node, that the quality of the at least one portion of the link has changed relative to a previous quality of the at least one portion of the link; generating, by the data plane node according to local control logic programmed into the data plane node, a decision specifying a placement for one or more RAN functions; and transmitting, by the data plane node to one or both of the radio unit and the central processing unit, a notification including the decision specifying the placement for the one or more RAN functions.
