  • Patent number: 11070434
    Abstract: A communications network node has a memory storing information about the topology of a network, configuration data comprising attributes of the network, and information about a routing protocol of the network. The memory stores a comparison function derived from a best path definition of the routing protocol. A path finding component of the node computes, for an individual one of the nodes, a routing table specifying which neighbors of the individual node incoming data received at the individual node is to be routed to, where computing the routing table comprises searching for optimal paths between the nodes, using the information about the topology of the network and the configuration data, and using the comparison function to guide the search; and wherein optimal paths between the nodes are optimal with respect to one or more of the attributes.

  • Patent number: 10986561
    Abstract: This disclosure provides systems, methods, and apparatus, including computer programs encoded on computer-readable media, for managing wireless local area network (WLAN) density. The WLAN density is managed to limit how many APs can utilize a first portion of a first frequency band in a geographical area. A limit of APs may be based on an estimated amount of interference that would be caused by the APs to an incumbent system that also uses the first portion of the frequency band. The WLAN density control may prevent the estimated amount of interference caused by APs in a geographical area from exceeding a threshold interference level based on the presence of the incumbent system. WLAN density control may involve the AP configuration of a first AP or may involve the density of client devices associated with one or more APs in the geographical area.
