Method and System for Preventing Loops in Mesh Networks
First Claim
1. A method comprising:
- receiving, at a network device at a first network node in a wireless network, a frame from a wired network, wherein the frame comprises a site identifier uniquely corresponding to the wired network and a destination physical address;
determining, by the network device, whether the network node is selected as a representative portal node based on the site identifier and the destination physical address; and
responsive to the first network node being selected as the representative portal node, forwarding, by the network device, the frame to a second network node.

Abstract
The present disclosure discloses a network device and/or method for preventing loops in routing paths of network frames in a wireless digital network. The disclosed network device at a network node receives a frame from a wired network. The frame includes a site identifier uniquely corresponding to the wired network, a source physical address, and a destination physical address. If the network node is selected as a representative portal node, the network device forwards the frame. Otherwise, if another network node is selected as the representative portal node, the network device drops the received frame to prevent forming a loop in a routing path corresponding to the frame. If not other network is selected as the representative portal node, the network device floods the frame to other network nodes in the wireless network.

8. A network device comprising:
-
a processor; a memory; a receiving mechanism coupled to the processor, at a first network node in a wireless network, the receiving mechanism to receive a frame from a wired network, wherein the frame comprises a site identifier uniquely corresponding to the wired network and a destination physical address; a determining mechanism coupled to the processor, the determining mechanism to determine whether the network node is selected as a representative portal node based on the site identifier and the destination physical address; and a frame handling mechanism coupled to the processor, the frame handling mechanism to forward, in response to the first network node being selected as the representative portal node, the frame to a second network node. - View Dependent Claims (9, 10, 11, 12, 13, 14)

15. A non-transitory computer-readable storage medium storing embedded instructions that are executed by one or more mechanisms implemented within a network device to perform a plurality of operations comprising:
-
receiving, at a first network node in a wireless network, a frame from a wired network, wherein the frame comprises a site identifier uniquely corresponding to the wired network and a destination physical address; determining whether the network node is selected as a representative portal node based on the site identifier and the destination physical address; and forwarding, in response to the first network node being selected as the representative portal node, the frame to a second network node. - View Dependent Claims (16, 17, 18, 19, 20, 21)
