Abstract: Networks with a plurality of independent nodes are useful when the nodes can communicate with one another and with nodes and resources outside the network. The present disclosure addresses ways to encapsulate packets as they move from a sender to a receiver, and also addresses ways for speeding up messages between nodes by orderly queuing and processing of messages. The present disclosure also includes techniques for mapping nodes in a home area network to IP addresses in a local area network.

Abstract: A system and method for transmitting packets to a plurality of network devices that cannot be accessed via a single multicast message is disclosed. The system includes a gateway controller that received a multicast request from a client, and creates a plurality of multicast messages based on the number of different security classes. The gateway controller parses the request from the client and identifies all of the desired destination nodes. The gateway controller then identifies the security class that each of these destination nodes belongs to. Based on this, the gateway controller then creates one or more multicast messages, where each multicast message is intended for the destination nodes that belong to a single security class. In certain embodiments, the gateway controller also aggregates the acknowledgments from the destination nodes and forwards this information to the client.
