Abstract: Network hardware devices organized in a wireless mesh network (WMN) in which one network hardware devices includes a first radio and a second radio coupled to a processing device. The processing device receives a request from a client consumption device via the first radio and determines a destination for the request as a second mesh network device. The processing device access a master routing table to determine that the second radio is to forward the request and forwards the request to the second radio. The second radio accesses a local routing table at the second radio to determine that a radio of a third mesh network device is a next-hop mesh network device in a first path to the second mesh network device. The second radio sends the request to the radio of the third mesh network device.

Abstract: A mesh network device includes a radio and an application processor including a hop-aware multicast engine to: determine a mesh header time to live (TTL) value for a broadcast frame in a data link layer. The mesh header TTL value is the lessor of an internet protocol (IP) header TTL value of the first broadcast frame in an IP layer and a predefined value. The broadcast frame includes a request for a service or a resource to be sent. The hop-aware multicast engine sends the broadcast frame to a first set of mesh network devices being defined by the mesh header TTL value. The hop-aware multi-case engine determines that a response was not received within a time period; increases the mesh header TTL value; and sends a broadcast frame to a second set of one or more additional mesh network devices being defined by the increased mesh header TTL value.

Abstract: Network hardware devices organized in a wireless mesh network (WMN) in which one network hardware devices includes multiple radios. A processing device of a first network hardware device scans a channel of the first radio for access point (AP) beacon frames that each contains information identifying a mesh network device in a WMN. The processing device creates a list of a plurality of mesh network device from the AP beacon frames and transmits a location probe transmission by each of the plurality of radios one sector at a time in a neighbor discovery process. The processing device receives metrics of the location probe transmissions received by the plurality of mesh network devices in the neighbor discovery process and configures each of the plurality of radios to communicate with one of a set of neighbor mesh network devices using the metrics in a neighbor selection process.

Abstract: Network hardware devices organized in a wireless mesh network (WMN) in which one network hardware devices includes multiple radios. A processing device of a first network hardware device receives, via a first radio, a beacon frame from a second mesh network device, scans, via a second radio, for a second mesh frame of the second mesh network device, and receives the mesh frame. The processing device determines a first sector identifier that identifies an antenna from which the mesh frame is transmitted, a first signal strength indicator value corresponding to the mesh frame, an unused radio and an unused channel of the second mesh network device. The processing device sends a first message to the unused radio of the second mesh network device on the unused channel via the second radio, receives a second message, and configures the multiple radios to communicate with the second mesh network device.
