  • Patent number: 11989834
    Abstract: Devices and techniques are generally described for three dimensional room modeling. In various examples, 3D mesh data representing a room may be received. Plane data comprising a plurality of planes may be received. Each plane of the plurality of planes may represent a planar surface detected in the room. In some cases, a first plurality of wall candidates for a 3D model of the room may be determined based at least in part on the plane data. A second plurality of wall candidates for the 3D model of the room may be determined by modifying the first plurality of wall candidates based on a comparison of the first plurality of wall candidates to the 3D mesh data. The 3D model of the room may be generated based at least in part on the second plurality of wall candidates.

  • Patent number: 11671366
    Abstract: A method may include (1) identifying a set of prefixes that (A) facilitate forwarding traffic within a network and (B) are organized as a tree data structure in connection with a table stored on a network device, (2) identifying, in the set of prefixes organized as the tree data structure, a parent prefix and a child prefix that corresponds to the parent prefix, (3) determining that the parent prefix and the child prefix share a certain number of most-significant bits in common with one another, (4) determining that the parent prefix and the child prefix share a forwarding behavior in common with one another and then, in response to determining that the parent prefix and the child prefix share the certain number of most-significant bits and the forwarding behavior in common with one another, (5) compressing the table stored on the network device by merging the child prefix with the parent prefix within the table. Various other apparatuses, systems, and methods are also disclosed.

  • Patent number: 10642650
    Abstract: In general, the disclosure describes techniques for distributing processing of routes among multiple execution threads of a network device. In some examples, a method includes identifying, with a thread of a plurality of execution threads, a first route processing thread of the execution threads to process a first route of a routing protocol, the first route received by the network device; identifying, with the thread, a second route processing thread of the execution threads to process a second route of a routing protocol, the second route received by the network device; processing, by the first route processing thread executing on a first core of the plurality of processing cores, the first route; and processing, by the second route processing thread executing on a second core at least partially concurrently with the first route processing thread executing on the first core of the plurality of processing cores, the second route.
