20130128726 | SYSTEM AND METHOD FOR PACKET DELIVERY BACKTRACKING - Traditional computer networks have been designed with the need for highly reliable packet delivery. This is largely handled by a centrally managed simple send-acknowledge protocol. In a highly dynamic mesh network, these methods are inadequate to ensure the most reliable packet delivery.

20140219091 | METHOD FOR CONTROLLING FLOOD BROADCASTS IN A WIRELESS MESH NETWORK - Computer networks with multiple nodes are often required to deliver packets to all nodes in the network, commonly referred to as “flooding.” Flooding is used to deliver multicast and broadcast packets generated by application, network and other layers of the networking stack. Flooding can be done very reliably but less efficiently via node to node “unicast” transmissions, or very efficiently but less reliably via “broadcast” transmissions. In order to balance reliability with efficiency, this invention defines a threshold for the number of neighboring nodes as seen by a given node prior to a flooding operation to determine whether data should be unicast or broadcast. Below that threshold, unicast is used; at or above that threshold, broadcast is used. The invention also incorporates knowledge of nodes seen in turn by neighbor nodes as part of this decision. | 08-07-2014 |
20150055471 | SYSTEM AND METHOD FOR QUALITY-BASED OPTIMIZATION OF NETWORK TRAFFIC - The protocol determines the quality of each node to node link(s), based on an exponentially weighted moving average of the time each packet spends within the network node. Once determined, that quality of link is then mapped into the physical QoS resources of the networking hardware in use (within the network). Packets destined for higher quality links will see an upgrade of their QoS rating, while packets destined to lower quality links will see a downgrade of their QoS rating. That adjustment permits the higher quality links to be processed before the lower quality links resulting in more efficient and complete communications in the network. Poorer quality links will no longer act as roadblocks to the higher quality packets. | 02-26-2015 |
20150271086 | Reducing Network Traffic By Intercepting Address Resolution Messages - Networks based on Internet Protocol (IPv4) employ an administrative Address Resolution Protocol (ARP) to convert logical IP addresses into physical Ethernet media access control (MAC) addresses. These queries address the entire network, and in very large networks, they contribute substantially to network traffic. This invention identifies ARP packets in a large, dynamic network and uses various means to minimize their broadcast throughout the network. This results in optimized network performance. | 09-24-2015 |
