摘要： A network element (101-104) of a software-defined network is adapted to construct a configuration system on the basis of configuration data received from a controller (105, 106) of the software-defined network. The network element is arranged to transmit, in response to an event indicating a need to verify the configuration system, status information to the controller. The event may include for example a loss and a subsequent re-establishment of a connection between the network element and the controller. The status information indicates a first portion of the configuration data which has been implemented in the configuration system prior to the event. After receiving the status information, the controller is able transmit an appropriate second portion of the configuration data to the network element so as to enable verification of an appropriate portion of the configuration system. Thus, there is no need to verify the whole configuration system after the event.

摘要： A network element of a software-defined network includes functional entities (321-325) capable of transferring data between each other and providing connections to other network elements. One or more of the functional entities are configurable with configuration data received from a controller of the software-defined network. The network element is adapted to transmit, to the controller, entity-specific capability descriptors related to the functional entities configurable with the configuration data. Each entity-specific capability descriptor expresses operations capable of being carried out by the respective functional entity. As the controller is made aware of the capabilities of the functional entities, the goal of the software-defined networking to provide controlled management of the data-forwarding functionality of a network element as a whole can be extended to the functional entities, e.g. line interface modules, so that each functional entity can be configured individually in accordance with the capabilities and resources of the functional entity.

摘要： In a data communication system according to the invention the functionality of the gateway device is distributed in a data communication network thereby reducing the need to direct the data traffic from and to terminals (212, 213, 214) through a single point in the data communication network. A first data communication device (207) is arranged to make, through signalling, second data communication devices (204, 205, 206) capable of directing the data communications of the terminals to the starting points of the respective logical data communication tunnels (215, 216, 217). This way there is no need for all logical data communication tunnels to start from, or depending on the direction, to end at, the same point in the data communication network.

摘要： A device for controlling a clock signal generator includes a processor (101) for forming at least two mutually different control quantities on the basis of reception moments of timing messages such as time stamps, where the reception moments are expressed as time values based on a first clock signal and the timing messages are transmitted in accordance with a second clock signal. The processor also calculates a weighted sum of the control quantities, and controls the clock signal generator with the weighted sum so as to synchronize the first clock signal and the second clock signal. The control quantities may represent, for example, a filtered value of observed phase-errors, a phase-error corresponding to a minimum observed transfer delay, and phase-errors corresponding to a given portion of the delay distribution. Using the weighted sum of the mutually different control quantities improves the utilization of the information content of the timing messages.

摘要： A satellite receiver module (101) for telecommunication equipment includes circuitries (102, 103) configured to receive timing information from one or more satellites and to form timing messages based on a clock signal in accordance with the received timing information. The clock signal is a stream of temporally successive clock pulses and the pulse-rate of the clock signal is accordant with a pace indicating signal received from a body device (110) of the telecommunication equipment. The satellite receiver module further includes a data interface (105) including a connector (106) for detachably attaching to the body device and for transferring the timing messages to the body device. Because the pulse-rate, i.e. the frequency, of the clock signal is accordant with the pace indicating signal received from the body device, a high-quality local oscillator is not necessary in the satellite receiver module.

摘要： A method for controlling advertising of routing data to neighbor routers is presented. A list of prefixes is maintained (301) and each prefix is associated (302) with an own indicator vector that contains a data item for each of the neighbor routers so that the data item indicates (304) whether the prefix concerned is to be advertised to the neighbor router concerned. For each neighbor router there is (303) a handling pointer pointing to the prefix that is relevant to the status of an advertising process related to this neighbor router, and the handling pointer is moved forward on the list of prefixes according as the prefixes are advertised to this neighbor router. As there is no need to maintain an own list of prefixes for each neighbor router separately, but only neighbor router-specific entries in the indicator vectors, savings can be achieved in the required memory space.

摘要： A device provided with fire protection includes a casing (102), electrical components (103) inside the casing, and a fan element (104). The casing includes a first wall having ventilation apertures and the fan element is configured to produce ventilation flow through the ventilation apertures so as to cool the electrical components. The device further includes a fire protection element (105) including thermally expanding material (109) configured to suppress the ventilation flow via the ventilation apertures in response to a situation in which the thermally expanding material is exposed to heat and gets expanded. The fire protection element is outside the casing, the fan element is mechanically supported to the casing, and the fire protection element is removable and re-installable without detaching the mechanical support between the casing and the fan element. Therefore, the fire protection element can be a post-installable element.

摘要： Equipment including at least one plug-in unit (102) and a body device (101) for receiving the plug-in unit is presented. The equipment includes a circuit (124) including a test signal generator for supplying a test signal to a measurement circuit including galvanic contacts provided by electrical connectors between the body device and a plug-in unit so that the test signal belongs at least partly to a frequency band used in data transfer between the plug-in unit and the body device. The equipment includes a monitoring circuit for generating a signal indicative of a difference between a quantity responsive to the test signal and a reference. As the test signal belongs at least partly to the frequency band used in the data transfer, the quality of the galvanic contacts between the body device and the plug-in unit can be monitored concerning the behavior on the data transfer frequency band.

摘要： The invention relates to allocating and releasing a memory organized to contain memory block groups each of which containing memory blocks. There is a first data entity (101) that indicates the number of free memory blocks in each memory block group. For each memory block group, there is a second data entity (102, 103, . . . , 105) that indicates which of the memory blocks of the concerned memory block group are free. When a request to allocate a memory block is received, a memory block group containing a free memory block is searched on the basis of the first data entity and, from this memory block group, a free memory block is searched on the basis of the second data entity relating to this memory block group. The first data entity and the second data entities constitute a compact data structure, and therefore a cache memory can be effectively utilized.

摘要： A device for controlling frequency synchronization includes a processor for controlling a frequency-controlled clock signal on the basis of received timing messages so as to achieve frequency-locking between the frequency-controlled clock signal and a reference clock signal. For the purpose of finding such timing messages which have experienced similar transfer delays and thus are suitable for the frequency control, the processor is configured to control a phase-controlled clock signal on the basis of the timing messages so as to achieve phase-locking between the phase-controlled clock signal and the reference clock signal, and to select the timing messages to be used for the frequency control on the basis of phase-error indicators related to the phase control. Thus, the phase-controlled clock signal is an auxiliary clock signal that is utilized for performing the frequency control.
