Abstract:
A method of dynamically controlling a maximal bandwidth limit of one or more clients in a network connecting the clients to a remote point through a plurality of nodes. The method includes monitoring one or more parameters of the traffic through a first node of the network, determining whether the value of the one or more monitored parameters fulfills a predetermined condition, changing the maximal bandwidth limit of one or more clients of the network, responsive to a determination that the value of the one or more parameters fulfills the condition and imposing the maximal bandwidth on the one or more clients by a second node of the network different from the first node.
Abstract:
A station to serve as a proxy for responding to a multicast message is selected using dynamically maintained information about other stations communicatively coupled to a shared communications network. The dynamically maintained information is used to select a station having a high probability of replying to the multicast message. Network performance may be further improved by re-selecting proxies when a multicast frame fails to acknowledged.
Abstract:
Bei einem Verfahren und einer Anordnung zur Übertragung von Daten innerhalb eines Kommunikationsverbunds (8; 23), wobei die Daten über ein leitungsgebundenes Übertragungsmedium (12; 22), z. B. ein Stromversorgungsnetz, übertragen werden, werden die Sendezeiten mindestens eines Sende-/Empfangsgeräts (10.1; 25.1) des Kommunikationsverbunds (8; 23) und eines Sende-/Empfangsgeräts (10.2; 25.5) ausserhalb des Kommunikationsverbunds durch ein vom Kommunikationsverbund (8; 23) unabhängiges Zeitsignal synchronisiert. Dadurch, dass sich die Sendezeiten des einen Sende-/Empfangsgeräts möglichst wenig mit den Empfangszeiten des anderen Sende-/Empfangsgeräts überlappen, werden Interferenzen zwischen Sende-/Empfangsgeräten unterschiedlicher Kommunikationsverbunde minimiert, wobei keine oder eine sehr geringe Reduktion der Bandbreite auftritt und ein Synchronisierungsvorgang zwischen Sende-/Empfangsgeräten verschiedener Kommunikationsverbunde vermieden wird.
Abstract:
A relay apparatus with a built-in power line communication modem comprises a modem part (51) for power line communication and a relay part (52) having a switching hub function. The relay part (52) can be connected to a computer, thereby allowing the modem part (51) to perform a power line communication, while the relay part (52) can be connected to a terminal device and/or a peripheral device, thereby constructing a network. The relay apparatus further comprises a plurality of electric outlets (4) to allow the devices connected to the relay part (52) to be supplied with power.
Abstract:
This patent relates to the handoff of an untethered device (493) connected to a tethered device (495) communicating on a power line communication (PLC) network (499) to another device communicating on a PLC network or communicating with a conventional communication network or communicated on a mesh communication network. An additional embodiment of the present invention is the bridging (662) of a first communication network (660) over a PLC network to a second communication network (664) and the switching into or out of a PLC network between two communication networks bridged through a device connected to a PLC network (499) such that the first communication network (660) or second communication network (664) disconnects from the PLC network while a third communication network (665) connects to the PLC network (499).
Abstract:
A power line communication system (Fig. 1) combining high bitrate and low bitrate transmission using radio frequency modulated carriers to communicate on a low voltage power line (1) to energize applicances.
Abstract:
The invention relates to a coupling module (1) via which communication becomes possible between different electronic appliances of an (in-home) network (30). To this end, the coupling module (1) can be expanded in modular fashion with transmitter and receiver modules (20 - 27), which in each case create a network interface with the electronic appliances, with the associated transmission protocol in each case. The coupling module (1) may preferably independently detect the connected appliances, and pass on incoming information to the particular addressee in the appropriate protocol.
Abstract:
A management block (VB) is provided for the management and operation of the transmission system, whereby each transmission device (UE) is provided with management information (vi). The management block (VB) is controlled, managed, and monitored by the first transmission device (UE) connected to the energy supply network (EVN) and the corresponding management information (vi) entered. Further transmission devices (UE) connected to the energy supply network (EVN), each monitor the management block (VB) and the management information (vi) pertaining thereto is entered in the management block (VB) by means of the first connected transmission device (UE). Installation and management of transmission devices (UE) connected to the energy supply network (EVN) is simplified by means of the above method.
Abstract:
A media adapter (286) for coupling a network device to a power line (210). The media adapter (286) comprises a physical layer (380), and an inter-working unit (390) in communication with the MAC layer (385). The inter-working unit (395) is adapted to translate information from a first format into a second format, which differ from the first format, to enable information to be received and transmitted over the power line (210).
Abstract:
A modem (104) which includes an application interface for receiving packets to be transmitted on an electrical power network (112), a network interface connecting the modem to the electric power network, at least one media access control (MAC) unit adapted to perform MAC layer tasks in accordance with at least two different MAC protocols (172), on packets received from the application interface, and at least one physical layer unit adapted to transmit packets from the at least one MAC unit onto the electric power network, through the network interface, in a same frequency band.
