摘要： A method, a system, and a network entity for performing the switch-over of a protected Label Switched Path (LSP) in (less than) 50 ms. A goal of the preferable arrangement is to move the tasks related to the switch-over away from the CPU to hardware (HW). The ASIC applies a communication protocol to signal a need for a switch-over between two (or several) units without CPU's participation. A unit, for example Sink of protected domain, which has detected a fault, sends a so-called protection message to a protection pair unit of the unit. The protection pair unit interprets the protection message and actives the connection on the protecting unit.

摘要： A method, a system, and a network entity enable a detection of a connection fault and perform the switch-over in less than 50 ms. CV packets are being sent, for example, 1/10 ms (1 CV packet per 10 ms) or 1/15 ms (1 CV packet per 15 ms). The interval of the CV packets, consequently the frequency for sending CV packet, can be any interval that makes the switch-over time for a protected substantially real-time connection achievable. Moreover, the interval (the frequency) should be such that the interval makes the fault detection from the fault event to occur in less than 50 ms and triggers the switch-over to occur also in less than 50 ms from the occurrence of the fault event.

摘要： A software-defined network includes a database (105) that is accessible to a controller system (108, 109) of the software defined network and also to network elements (101-014) of the software defined network. The controller system determines configuration data and delivers it to the database. Each network element retrieves its part of the configuration data from the database and implements the retrieved part of the configuration data into its own configuration system that enables the network element to operate as a part of the software-defined network. The commonly used database facilitates maintaining the congruence between the network elements and the controller system of the software-defined network.

摘要： In a system, the functionality is decentralized in a data transmission network so that the need of communications produced by and addressed to data terminals to pass by way of a single point in the data transmission network is diminished. A first data transmission installation is adapted to signal second data transmission installations, each of which is part of a ring-shaped data transmission topology, to be capable of building logical data transmission tunnels directed to the data terminals. Thereby, all the logical data transmission tunnels need not commence or, depending on the direction, terminate at the same point of a data transmission network. In addition, the data transmission installations present in a ring-shaped data transmission topology need not necessarily be taught routing information in order to enable each of these data transmission installations to send data transmission frames to be transmitted to another one of these data transmission installations.

摘要： An electrical device includes a magnetic sensor circuitry (101) for detecting magnetic field and for generating a detection signal in response to the detected magnetic field, and a control circuitry (102) for controlling operation of the electrical device in accordance with the detection signal. The magnetic sensor circuitry is configured to detect a direction related to a deviation of the magnetic field from the magnetic field of the earth, and the control circuitry is configured to control the operation of the electrical device in accordance with the detected direction. The electrical device can be controlled by using e.g. a permanent magnet (105) for directing, to the magnetic sensor circuitry, magnetic field deviating from the magnetic field of the earth and having a desired orientation. Thus, the electrical device can be controlled without an electrical connector or a radio interface.

摘要： A method for optimizing entity-specific configuration systems for functional entities of a network element of a software-defined network is presented. The entity-specific configuration systems are based on a network element-specific configuration system related to the whole network element and including configuration entries for determining operations to be carried out by the network element. The method includes forming (401) relation data that indicates, for each of the functional entities, those of the configuration entries which are irrelevant to the functional entity under consideration so that operation of the functional entity is independent of these configuration entries. The relation data enables the entity-specific configuration systems to be constructed (402) so that the entity-specific configuration system of each functional entity is free from those configuration entries which, according to the relation data, are irrelevant to the functional entity under consideration. Therefore, resources for implementing the entity-specific configuration systems can be saved.

摘要： A method for configuring a network element of a software-defined network “SDN” includes retrieving (401), for different look-up tables, a look-up table specific resource consumption estimate indicating a load factor of at least one component of the network element when running operations related to the look-up table, determining (402), on the basis of the look-up table specific resource consumption estimates, a resource consumption estimate for at least one look-up system including one or more of the look-up tables and having functionality suitable for the network element, and sending (404) to the network element, if the network element is capable (403) of running the look-up system, configuration data defining the look-up system. The method provides a possibility to avoid configuring network elements to overload and, on the other hand, the resource consumption estimates related to different network elements can be used for optimizing the software-defined network as a whole.

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.

摘要： The invention relates to a method and equipment for performing flow shaping that maintains service quality in packet-switched telecommunications. Using the method according to the invention, the speed properties (CIR, PIR, CBS) of an aggregate flow (A) can be monitored and limited in a situation, in which the aggregate flow contains delay-critical traffic (V1), the forwarding of packets representing which cannot be delayed. The invention is based on the fact that, when forwarding packets representing the aggregate flow, a variable is updated, the value of which expresses the earliest permitted moment, at which a packet, representing traffic (V2) other than the delay-critical traffic, can be forwarded. In that case, the transfer speed of the traffic (V2) other than delay-critical traffic adapts to the variations in the transfer speed of the delay-critical traffic, allowing the speed properties of the aggregate flow to be monitored and limited.

摘要： The invention relates to transmitting digital information between the network elements of a frame switched data network. In the present invention, it has surprisingly been discovered that the padding bits of the data field of a minimum sized Ethernet frame can be used for transmitting digital information between the elements of a data network. In that case the frame data field (109) of a minimum sized Ethernet frame contains an information unit (DIU), the size of which in bytes is smaller than the minimum size of a frame data field, as well as other digital information (DI) that is written in an area (107) of the frame data field that corresponds to the padding bits. The invention makes it possible to also utilize the data transmission capacity needed for transmitting the padding bits.
