A network node (15) is configured to switch data packets between a Remote Radio Unit (2) and a Digital Unit (4). The network node comprises one or more input port (33) configured to receive said data packets (52a) and receive further packets having a destination other than one of a Remote Radio Unit and a Digital Unit. One or more output port (35) is configured to transmit said data packets and said further packets. A scheduler (31) is configured to control transmission from the output port according to a scheduling cycle (41a). The scheduler is configured to schedule only said data packets to be transmitted in a first period of the scheduling cycle, and schedule one or more of said further packets to be transmitted in a separate second period of the scheduling cycle.
