1. A system for networking in a hybrid mesh network, the system comprising:
- a first node configured to be deployable among a plurality of nodes in the hybrid mesh network, the first node being further configured to be communicatively connected to a second node of the plurality of nodes by a wireless connection, and to be communicatively connected to a root node, wherein the first node includes a wired communication interface, a wireless communication interface and a packet forwarding logic between said wired and wireless interfaces; and
wherein the first node is configured to detect that the first node is communicatively connected to the second node by a wired connection in addition to the wireless connection by receiving a wired beacon, to determine, in response to receiving an approximation uplink throughput of the second node through the root node, that the first node has an uplink throughput to the root node that is greater than that of the second node, and, in response to the detection and the determination, to suspend said packet forwarding logic between said wired and wireless interfaces of the first node to break a loop between the wired connection and the wireless connection, and wherein the first node continues to receive wired beacons from a plurality of other nodes in the hybrid mesh network by way of the suspended wired connection with the second node;
wherein the first node is further configured to suspend the packet forwarding logic of the wireless connection based on detection of an appearance of a source packet on multiple ports.

Abstract
Embodiments of the present invention solve problems experienced by mesh networks concerning loop formation where two nodes are connected by both a wired and wireless link. The present invention prevents or ‘breaks’ a loop that that would otherwise result in continually repeating and delayed network data transmission.

11. A method for networking in a hybrid mesh network, the method comprising:
-
detecting, by a first node configured to be deployable among the hybrid mesh network, a presence of a second node in the hybrid mesh network, wherein the first node includes a wired communication interface, a wireless communication interface and a packet forwarding logic between said wired and wireless interfaces; determining, by the first node, that, in addition to being communicatively connected by a wireless connection, the first node and a second node have become communicatively connected via an Ethernet connection; and
in response to receiving an approximation uplink throughput of the second node through a root node, determining, by the first node, that the first node has an uplink throughput to the root node that is greater than that of the second node; andin response to the detection and the determination, suspending said packet forwarding logic between said wired and wireless interfaces of the first node to break a loop between the wired connection and the Ethernet connection, and wherein the first node continues to receive wired beacons from a plurality of other nodes in the hybrid mesh network by way of the suspended Ethernet connection; wherein the determination that the first node and the second node have become communicatively connected via the Ethernet connection is based on detection of a source packet on multiple ports. - View Dependent Claims (12, 13, 14, 15)
