Methods and apparatus for a scalable network with efficient link utilization
First Claim
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.

Abstract
In some embodiments, an apparatus comprises a core network node configured to be operatively coupled to a set of network nodes. The core network node is configured to receive a broadcast signal from a network node from the set of network nodes, which is originated from a host device operatively coupled to the network node. The broadcast signal is sent via a tunnel from the network node to the core network node, such that other network nodes that are not included in the tunnel do not receive the broadcast signal. The core network node is configured to retrieve control information associated with the broadcast signal without sending another broadcast signal, and then send the control information to the network node.

12. A. non-transitory processor-readable medium storing code representing instructions to cause a processor to:
-
receive, at a network node configured to be included in a plurality of network nodes, a broadcast request signal from a host device operatively coupled to the network node, the broadcast request signal requesting control information; send, via a tunnel between a core network node and the network node, a signal based on the broadcast request signal to the core network node such that the core network node retrieves the control information without sending a broadcast 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 remaining network nodes from the plurality of network nodes, the signal being sent to the core network node such that the remaining network nodes from the plurality of network nodes do not receive the broadcast request signal; receive, via the tunnel, the control information from the core network node; and send a unicast signal including the control information via the tunnel to the host device. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20)

21. An apparatus, comprising:
-
a network node configured to be included in a plurality of network nodes operatively coupled to a core network node, the network node configured to receive a first signal from a host device operatively coupled to the network node, the network node configured to send a second signal in response to a determination on that the first signal (1) is associated with one of an address resolution protocol (ARP) request, a dynamic host configuration protocol (DHCP) request or a neighbor discovery (ND) request, and (2) originated as a broadcast request signal from a host device operatively couple to the network node, to the core network node via a tunnel between the network node and the core network node, the tunnel including at least one intervening network node from the plurality of network nodes between the core node and the network switch and excluding remaining network nodes from the plurality of network nodes, the network node configured to send the signal such that the remaining network nodes from the plurality of network nodes do not receive the broadcast request signal, the network node configured to receive control information in response to the core network node retrieving the control information without sending broadcast signal and based on the broadcast request signal. - View Dependent Claims (22, 23, 24, 25)
