Abstract: A system, method and non-transitory computer readable media for facilitating network connectivity in a split architecture fronthaul network (102) comprising a plurality of cells (118-1 to 118-5, 120-1 to 120-5) and one or more BBU hubs (108A, 108B), each hub comprising at least a BBU (110-N, 112-M). An example cell allocation process (400B, 500A) is configured to assign cells to the hubs sequentially, i.e., a hub must be completely full (e.g., with respect to certain predetermined capacity such as port utilization) before adding cells to any other hubs. Once a hub is full, the allocated cells are further assigned to the individual BBUs of the hub also sequentially (500B). An optimal cell allocation map (418) is thereby obtained, which may be used in (re)configuring the connectivity between the cells (118-1 to 118-5, 120-1 to 120-5) and the hubs/BBUs (110-N, 112-M).
