Abstract: A method for selecting a router node in a LLN (Low power and Lossy Network) type telecommunication network wherein, upon receipt by a router node of a data packet from a host node or an adherence request to a multicast group from a host node, the router node transmits to a root node a MER_Request request of configuration as a multicast router node to serve the host node, and upon receipt of the MER_Request request, the root node determines, from an association table, a configuration of the router node and transmits to the router node a MER_Reply reply message including the determined configuration.

Abstract: A method for preselecting a router in a LLN (Lower power and Lossy Network) network from a plurality of nodes in which each router node transmits to the other router nodes of the LLN network within direct radio range of the router node an announcement message, and, upon receiving the announcement message, each of the other router nodes compares its current status with respect to a router node with the status indicated in the announcement message, and configures its status depending on the comparison so that a single node from among the nodes of the LLN network within direct radio range of the router node transmits to the root node a configuration request MER_Request as a multicast router for data from or intended for the host node.

Abstract: Systems, methods, and computer-readable media provide a mapping database for mapping device identifiers to network addresses and vice versa. Device identifiers and their corresponding network addresses may be stored in the mapping database. Data may be received from an input/output device and converted into a device identifier. Also, data may be received through a user device and converted into a network address. The mapping database may be populated using various protocols. Further, the mapping database may store various types of network addresses so that a controller may communicate with various types of input/output devices using various protocols.
