A method for managing data in a communication network (10) includes a connection (20), in particular a switch, and at least one local communication terminal connected to the connection device (20). The connection device (20) is connected to or equipped with a second management information base (MIB), in which information related to the location of the communication terminal is written and is made available for use in a location-dependent service during a data management process, the location-dependent service being designed according to a discovery protocol. The data management process involves feeding the location-related information to the communication network (20) using a location information source (3) and transmitting the fed location-related information from the location information source (3) to the connection device. Across at least one section of the transmission path, the fed location-related information is transmitted according to the discovery protocol.

The embodiments of the present invention provide a method for heartbeat packet processing by using a proxy, an apparatus, and a communications system. The method includes: receiving, by a host, a first heartbeat packet sent by a first application in a client, where the client is a terminal that accesses the host by using a short range communications technology; and determining, by the host according to the first heartbeat packet and a first preset list, whether the first application is included in the first preset list. Thus, an objective of saving power for the host and the client can be achieved.

A method and communication system for transmitting time-critical data, wherein selected datagrams are assigned to data streams and transmitted via paths for the data streams, where reservation requests are transmitted to a higher-level communication controller to reserve resources to be provided by the communication devices for transmitting data streams, in each case via a reservation function component, which is assigned to a first or second communication terminal or a communication device that is connected to the communication terminal and forwards datagrams, and where in the event of reservation requests, the higher-level communication controller ascertains a respective path and checks whether sufficient resources for transmitting the data streams while maintaining the specified service quality parameters are available in communication devices along the respective path, and the higher-level communication controller ascertains a proposed local cycle duration for selected communication devices.

According to various embodiments, an electronic device comprises a communication processor, an application processor operatively connected to the communication processor, and a memory, wherein the at least one memory may store instructions configured to, when executed, cause the application processor to identify a user identifier (UID) corresponding to at least one allowed application or at least one disallowed application when the electronic device enters a power saving state and to generate, on the basis of the user identifier, a first packet filter program which includes at least one condition for filtering a packet, and cause the communication processor to identify the first packet filter program generated from the application processor and to filter at least one packet associated with an application other than the at least one allowed application or at least one packet associated with the at least one disallowed application by using the first packet filter program, while the electronic device is in the power saving state. Various other embodiments are possible.

In one embodiment, a method for saving power on a mobile device includes receiving an indication of termination of a power-save mode of the mobile device, and requesting presence information for a plurality of peers of a user from a server or a P2P communication network in response to the received indication.

Example implementations relate to configuring network devices. For example, a network device includes a controller module to receive a link layer discovery protocol (LLDP) message from a second network device in response to determining that connection to a management device has failed. The controller module is to send a second LLDP message to the second device, where information contained is the second LLDP message is routed to the management device by the second device. The controller module is further to receive configuration changes from the management device and connect to the management device based on the configuration changes, where the configuration changes are routed by the second device.

A device may cause an optical signal to be transmitted via a network path. The device may receive, from a network device, a link layer discover protocol (LLDP) message. The LLDP message may include signal characteristic information regarding the optical signal. The device may adjust transmission of the optical signal based on receiving the LLDP message. The device may cause an adjusted optical signal to be transmitted via the network path based on adjusting transmission of the optical signal.

A computer network includes a server computer having communication ports that are wired to switch ports of two separate network switches. The network switches receive link aggregation control packets from the server computer, and automatically aggregate corresponding switch ports into a single logical port channel based on contents of the control packets.

A WSN has multiple sensor nodes, a bi-directional gateway sensor node, and a server. The WSN also includes circuitry configured to process a route request message from an origination sensor node to a destination sensor node. A message packet of each of the sensor nodes includes a minimum energy field, a minimum energy harvesting rate field, and a sum of energy field. The circuitry is also configured to determine a new delivery route based upon comparing a minimum energy and a minimum energy harvesting rate of an instant sensor node with a minimum energy and a minimum energy harvesting rate contained in the message packet, and select a lower minimum energy and a lower minimum energy harvesting rate from the instant sensor node or the message packet. The circuitry is also configured to broadcast the lower minimum energy and the lower minimum energy harvesting rate throughout the WSN.

An information handling system is provided. The information handling system includes a plurality of aggregation devices configured to distribute information in a virtual link trunk and a plurality of nodes coupled to the aggregation devices. When one of the plurality of aggregation devices received a reboot command, that aggregation device is configured to transmit a first message to the nodes indicating that the aggregation device is rebooting, receive a first acknowledgement message from the nodes indicating that they will not send any information to the rebooting aggregation device. The aggregation device is then configured to reboot, receive a second message from the nodes indicating the nodes are ready to receive information from the rebooted aggregation device, transmit a second acknowledgement message to the nodes indicating that the rebooted aggregation device has rebooted and is capable of receiving information, and receive information from at least one of the nodes for transmission to at least one other node.
