摘要： 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.

摘要： 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. This invention uses the natural redundancy of routes in a mesh and other techniques to increase the reliability of a network, even as the paths to any given node are dynamic in nature.

摘要： A system and method for controlling dynamic transmit power in a mesh network are disclosed. Distributed power transmit management methodology that implements transmission power management based on a comparison of signal to noise ratios from received beacon packets is used on a peer-to-peer basis. Embodiments work to keep all nodes accessible, dynamically adaptable to constant changes in the network, maximize frequency reuse, and reduce power requirements to maximize network performance while minimizing interference.

摘要： 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.

摘要： 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.
摘要翻译：该协议基于每个分组在网络节点内花费的时间的指数加权移动平均值来确定每个节点到节点链路的质量。一旦确定，那么链路的质量然后被映射到正在使用的网络硬件（在网络内）的物理QoS资源。以更高质量链路为目标的数据包将看到其QoS等级的升级，而分配到较低质量链路的数据包将降低其QoS等级。该调整允许在较低质量链路之前处理较高质量的链路，从而在网络中实现更高效和完整的通信。较差的质量链接将不再作为更高质量数据包的障碍。
