The present disclosure relates to a management device in a network system. The network system includes at least one slave device. The management device is communicatively connected with the at least one slave device. The management device includes a memory, and a processor communicatively coupled with the memory and configured to: receive, from one or more slave devices of the at least one slave device, function information of functions supported by the one or more slave devices; summarize the received function information and function information of functions supported by the network system which is stored in the management device; determine function information of the summarized function information, a function corresponding to which a control device is to be determined for; and determine the control device for the function to which the determined function information corresponds, from the management device and the at least one slave device.

Upon acceptance of a setting instruction for communication equipment (110), a first control apparatus (200) transmits a first setting command to the communication equipment, and updates first management information to information associated with first setting. When an event is detected, a second control apparatus (300) transmits a second setting command to the communication equipment and transmits a second setting notification to the first control apparatus. When the first control apparatus receives the second setting notification, the first control apparatus updates the first management information to information associated with second setting.

A network comprises ingress nodes, egress nodes, primary switches, and secondary switches where any pair of an ingress node and an egress node connects to orthogonal sets of primary switches and each secondary switch connects a respective set of primary switches to an orthogonal set of primary switches. Thus, each ingress node has a primary path and numerous compound paths to each egress node. The primary path traverses a respective primary switch, and each compound path traverses a first primary switch, a secondary switch, and a second primary switch. The disclosed connectivity pattern enables network scalability to accommodate hundreds of thousands of ingress-egress node pairs while permitting a significant proportion of incoming data to be routed through the primary switches avoiding the secondary switches.

A Transparent Interconnection of Lots of Links (TRILL) network establishing method, node, and system. The TRILL network establishing method includes: receiving, by a first node, a Link Layer Discovery Protocol (LLDP) packet, where an optional type-length-value (TLV) field of the LLDP packet includes TRILL capability information of a second node that sends the LLDP packet; and if it is determined, according to the TRILL capability information, that the second node has a TRILL capability, and the first node itself also has the TRILL capability, configuring, by the first node, a port, through which the LLDP packet is received, of the first node, to have a TRILL function enabled. The node in embodiments of the present invention can automatically enable or disable the TRILL function, so as to implement automatic establishment of a TRILL network.

An automation system that does not require any of the source node devices transmitting packets of information to have knowledge of the recipients of those packets. The automation system comprises sensor nodes and actor nodes. The sensor nodes transmit information via a wireless network based on conditions that are sensed by the sensors, such as a button being pushed, motion being detected, or the current ambient light level. The actor nodes detect the information that is transmitted over the wireless network and control their device functions, such as lighting and climate control, based on the information detected. In particular, the actor nodes monitor the network for packets that contain information that is relevant to each node, such as one or more sensor node source addresses previously configured to be of interest to each actor node and which are used in the decision-making that is performed by each actor node.

Representative implementations of devices and techniques provide an efficient communication that enables nodes in a reduced power consumption state to resume a regular power state (e.g., fully operational) or otherwise another power state (e.g., semi-operational) after processing the communication.

An electronic terminal device can be configured using a device identifier that is input into the device. The terminal device sends the device identifier to a configuration server. The configuration server responds by sending configuration information to the terminal device based on the device identifier.
