摘要： The invention relates to determining a quantity to be measured from a communication system, such as a transmission delay or the phase difference of clock times. Measurement messages are transmitted (501, 502) between the two areas of the communication system in both transmission directions. Values of the time difference are calculated (503) for the measurement messages transmitted in at least one of the transmission directions, each of which values is the difference between the instant of reception measured at the reception and the instant of transmission measured at the transmission of the measurement message. The values of the time difference are used to calculate (504) an estimate of the distribution of the time difference, on the basis of which an estimate of the minimum value of the time difference is calculated (504).

摘要： The invention relates to a method and equipment for performing aggregate-portion-specific flow shaping in packet-switched telecommunications, in such a way that the traffic flows (V1-VL) arriving in the system can be arbitrarily bundled into shaping groups and the speed properties (CIR, PIR, CBS) of an aggregate portion formed of packets representing the arbitrary shaping group (k) can be monitored and limited (aggregate-portion-specific shaping group). The invention is based on the fact that the earliest permitted moment, at which a packet in the system can be forwarded, is defined as the greatest value of the VTS values of all the shaping groups to which the traffic flow represented by the packet belongs, and as a result of the forwarding of the packet, the VTS values of the same shaping groups (k) are updated, in which the VTS value of an individual shaping group (k) expresses the earliest permitted moment, at which a packet belonging under the relevant shaping group (k) can be forwarded, without breaking the restrictions of the speed properties of the shaping group (k) being examined.

摘要： In a filter structure for suppressing a spurious signal, a conductor layer in a printed circuit board includes a pattern with interconnected pattern elements (106 to 114). A pattern element includes a low-impedance conductive region (119) the capacitance of which against a second conductor layer of the printed circuit board is dominant over the inductance. A pattern element includes at least two adjacent high-impedance conductor strips (115, 116) in a first direction, connected to a low-impedance conductive region, and at least two adjacent high-impedance conductor strips (117, 118) in a second direction, connected to the low-impedance conductive region. The inductance of each high-impedance conductor strips is dominant over the capacitance against the second conductor layer. The high-impedance conductor strips form together with the low-impedance conductive region a plurality of resonance points in the frequency range, thus achieving sufficient stop-band width

摘要： The invention relates to a method and equipment for controlling the congestion management and transmission-link-capacity scheduling in packet-switched telecommunications, in such a way that 1) it is possible to define what share of the capacity of the transmission link will be reserved for traffic representing a specific service level class, and 2) it is possible to define the weighting coefficient that the portion of the traffic exceeding the reservation of each service level class will use to compete for the portion of the capacity of the transmission link that is not reserved, or that is reserved but is not being used momentarily by traffic entitled to the reservation, and 3) it is possible to use overbooking, in such a way that the reduction in service quality due to overbooking affects only the service level class in which overbooking is used, and 4) it is possible to prevent an increase in delays detrimental to traffic-flow control even in a congestion situation arising from overbooking. The invention is based on measuring the traffic flow that comes to be scheduled, in which the flow is formed of packets representing a specific service level class arriving in the queue, or some of the relevant packets, and on controlling the operation of the scheduler and congestion limitation mechanism on the basis of the measurement results.

摘要： The present invention concerns adjustment of tap coefficients of a Tomlinson-Harashima precoder in a digital communications path during a data transmission state. According to the invention, the tap coefficients of the Tomlinson-Harashima precoder are adjusted based on content values of a delay line of the Tomlinson-Harashima precoder and on an error variable associated with a receive. Synchronization between the error value and the content values of the delay line is performed according to line frame synchronization information.

摘要： Each received piece of configuration data is added at a next currently free location in a volatile buffer. The contents of the volatile buffer are compressed after adding each received piece of configuration data. The compression result is stored in a non-volatile flash memory. If the compression result was shorter than a limit, it is allowed to be overwritten in the flash memory by a next compression result. If the compression result was longer than the limit, it is stored in the flash memory and the next compression result is directed to a different location in the flash memory.

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.

摘要： The invention relates to a method and apparatus for scheduling transmission link bandwidth between packet-switched data flows so that a desired CoS (Class of Service) is provided with an ability to utilize the instantaneously available bandwidth of a data transmission network while simultaneously offering a guaranteed minimum data rate (Guaranteed Data Rate and Best Effort) without compromising the operation of such classes that have no guaranteed lower bound of data rate, but instead, have the service implemented by the utilization of the instantaneously available bandwidth (Best Effort). The invention is based utilizing in the scheduler control, not only the information indicating the class of service, but also the information indicating the subgroup inside a class of service (e.g., drop precedence). The information indicating the subgroup is conventionally utilized only for congestion control purposes.

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.
