  • Patent number: 9602227
    Abstract: Systems, methods and apparatuses for supporting broadcast traffic through a wireless mesh network are disclosed. One method includes obtaining broadcast listening information of a broadcast listening access node, wherein the broadcast listening information includes an identifier of the broadcast listening access node, and a broadcast identifier of the broadcast listening device. The method further includes obtaining broadcast sourcing information of a broadcast sourcing access node, wherein the broadcast sourcing information includes an identifier of the broadcast sourcing access node, and a broadcast identifier of the broadcast sourcing device. The method further includes providing broadcast listening information of the broadcast listening access node to the broadcast sourcing access node upon determining the broadcast identifier of the broadcast sourcing device matches the broadcast identifier of the broadcast listening device.

  • Patent number: 9247397
    Abstract: Systems, methods and apparatuses for distributing multicast traffic through a wireless mesh network are disclosed. One apparatus includes an access node that includes one or more transceivers for communicating with other devices of a wireless mesh network, and a processor. The processor is operative to receive a unicast IP packet that includes a special destination IP address through at least one of the one or more transceivers, determine, based on the special destination IP address and a multicast group ID of a multicast distribution table, whether to forward the unicast IP packet to a downstream device, and route the unicast IP packet to the downstream device based on the determination.

  • Patent number: 9247417
    Abstract: Systems, methods and apparatuses of supporting multicast traffic of a wireless mesh network are disclosed. One apparatus includes an access node that includes one or more transceivers for communicating with other devices of a wireless mesh network, and a processor. The processor is operative to receive multicast traffic from a multicast traffic source through the one or more transceivers, associate the multicast traffic with a multicast group ID, and encapsulate the received multicast traffic in unicast IP packets that include a special destination IP address associated with the multicast group ID.
