摘要： Techniques for bridging communication between multiple networks to facilitate distribution of multicast data are described herein. For example, a node that is able to communicate with its network and an adjacent network may send a subscription message indicating that the node is a member of a multicast group. The subscription message may be forwarded up both networks. The node may then forward, between the networks, data that is destined for members of the multicast group.

摘要： Source routing techniques include sending data across several networks, while limiting source routing overhead. For example, the source routing techniques may use a first address format to route data to nodes along a routing path that are within a first network where a source node is located, and use a second address format to route the data to a node along the routing path that is within a second, different network. The node in the second network may similarly route the data through the second network using the first address format for nodes within the second network and, if needed, route the data to a node within a third network using the second address format. This may be repeated for any number of networks to reach a destination.

摘要： Techniques for limiting forwarding of multicast communications are described herein. For example, the techniques intelligently forward data along paths of a network where members of a multicast group are located. As such, nodes that do not lead to members of the multicast group may be pruned from distribution of the data. This reduces network communications, ultimately conserving processing, communication, and/or battery resources of the nodes.

摘要： Techniques for bridging communication between multiple networks to facilitate distribution of multicast data are described herein. For example, the techniques may identify a particular node that is able to communicate with each network and instruct the particular node to act as a bridge between the networks. The particular node may forward data from either network to the other network. This may allow data for a multicast group to be distributed to members of the multicast group that are located in separate networks.

摘要： Techniques for broadcasting data in a multi-channel network having a control channel and multiple data channels are described. A node wishing to broadcast data may determine a particular data channel from among the multiple data channels, a modulation technique, and a data rate to be utilized to broadcast the data. The broadcasting node may transmit a message over the control channel indicating that the data will be broadcast on the particular data channel using the modulation technique and at the determined data rate. The broadcasting node and a node wishing to receive the data may switch to the particular data channel. The broadcast node may broadcast the data over the particular data channel, while the receiving node may receive the data. After broadcasting the data or a predetermined time period has expired, the broadcasting node and receiving node may switch to the control channel.

摘要： In a wireless and/or power line communication (PLC) network environment, techniques for multicast of data and management of multicast groups assist in regulating bandwidth consumption and provision of desired multicast data. Nodes indicate interest in multicast groups by transmission of reports upstream. Report transmission may be suppressed to balance bandwidth with need for multicast data. Multicast data packets may be retransmitted downstream to fulfill requests indicated by the reports at a rate and/or frequency based on multicast packet duplication or redundancy. Information, such as broken links or “leave” packets, may indicate that one or more downstream nodes should be removed from a forwarding state. However such removal may impact other nodes. A query may be transmitted downstream, to determine if retransmission/forwarding of multicast retransmissions should continue. Query transmission may be based on a balance between query bandwidth consumption and the needs of downstream nodes.
