A method and an apparatus for communications systems provide priority to packets entering a communications node from a network to enable transmission of these packets in an orderly and efficient fashion. By defining a through-traffic preemptive priority mode, local packets are held in abeyance until packets which are already on the network and detected at the communications node have been routed through the node. Then the local packets are allowed to be transmitted from the node. And by defining a through-traffic priority mode, the local packet once started is completely transmitted before the network packets entering the communications node are allowed to continue through the system.
