1. An apparatus, comprising:

  • a core network node configured to be operatively coupled to a plurality of network nodes,the core network node configured to receive, from a network node from the plurality of network nodes, a signal (1) originating as a broadcast request signal from a host device operatively coupled to the network node, and (2) tunneled to the core network node from the network node in response to a determination that the signal is associated with the broadcast request signal such that the remaining network nodes from the plurality of network nodes do not receive the broadcast request signal, the tunnel including at least one intervening network node from the plurality of network nodes between the core network node and the network node and excluding the remaining network nodes from the plurality of network nodes,the core network node configured to retrieve control information associated with the broadcast request signal without sending a broadcast signal, the core network node configured to send a unicast signal including the control information via the tunnel to the network node.
