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： 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.

摘要： The invention relates to transmitting time information between elements of a data network. In the present invention, it has surprisingly been discovered that in a network transmitting packet, frame or cell switched data traffic, time stamp information can be transmitted from a network element (101) to another network element (102) by using that part (113a, 113c) of the bit stream (111b) to be transmitted which is connected, in the transmitting network element (101), to the transmitted bit stream in a location that is placed, in the flowing direction of the transmitted bit stream, after a transmission buffer (103) buffering data packets, frames or cells. In an arrangement according to the invention, the random-type share of the transmission delay experienced by the time stamp information is slight, because the time stamp information does not have to queue in the transmission buffer (103) buffering data packets, frames or cells.

摘要： The invention relates to a method and an arrangement for regenerating a timing signal in digital data communication where two network elements operate in a master/slave loop timing mode. In a solution according to the invention two different frequency difference indicators are formed. Values or changes of the values of both of them in relation to time indicate a frequency difference between a reference timing signal present in a master device and a regenerated timing signal present in a slave device. One frequency difference indicator is formed on the basis of reception taking place in the master device, and the other one on the basis of reception taking place in the slave device. The frequency of the regenerated timing signal is adjusted utilizing information contained by both frequency difference indicators. The probability of incorrect frequency adjustment measures can be thereby reduced.

摘要： The invention relates to a method and system for adjusting a clock signal placed in a network element of a data network. The clock signal is adjusted on the basis of difference values formed by means of received synchronizing messages. Each difference value is a difference of a reception time value and a transmission value of a received synchronizing message. The reception time value of the synchronizing message depends on a cumulated number of periods of the clock signal at a moment of arrival of the synchronizing message, and the transmission value depends on a position of the synchronizing message in a chronological transmission order of the synchronizing messages. In the adjusting process, an adjusting effect of the difference values belonging to a lower part (304) of a margin of fluctuation (306) of the difference values is weighted more heavily than an adjusting effect of the difference values belonging to an upper part (305) of the margin of fluctuation of the difference values. Thus, for adjusting the clock signal, there can be used that share of information represented by the received synchronizing messages that has the least interference, irrespective of the load situation of the data network.
摘要翻译：本发明涉及一种用于调整放置在数据网络的网络元件中的时钟信号的方法和系统。基于通过接收到的同步消息形成的差值来调整时钟信号。每个差值是接收时间值和接收到的同步消息的发送值的差。同步消息的接收时间值取决于同步消息到达时刻的时钟信号的累计数量，并且发送值取决于同步消息的时间顺序的同步消息的位置。在调整处理中，属于差值的波动余量（306）的下部（304）的差值的调整效果比属于上部的差分值的调整效果（ 305）的差异波动幅度。因此，为了调整时钟信号，可以使用由接收到的具有最小干扰的同步消息表示的信息的共享，而与数据网络的负载情况无关。

摘要： The invention relates to producing data traffic where the time intervals between successive data frames follow a predetermined probability distribution. In the present invention, it is surprisingly discovered that a time interval of a desired length between successive data frames can be produced by setting a certain bit quantity of digital stuffing data, defined on the basis of the target length of the time interval target, in a buffer memory (101), where successive data frames are waiting to be transmitted. The digital stuffing data is set in the buffer memory (101), so that the stuffing data is, in the read-out order, located between successive data frames.
