摘要： A method of detecting an unsatisfactory quality of service being experienced by users of a communications network (100) comprises a network monitoring system (135) for generating data record feeds (302) concerning traffic generated by the users. A pattern matching engine (304) is provided to recognise repeated failed attempts to establish a call between users of the communications network (100) or repeated calls of impractically short duration. The pattern matching engine (304) generates (506) an alert or alarm in response detection of such usage behaviour from the data record fees.

摘要： A dual port memory is updated at substantially the same data sampling rate as a clock frequency of the dual port memory. The dual port memory stores data relating to each different parameter value in a stream of data samples, and provides the stored data from an address in the memory corresponding to the received parameter value. An updating element updates stored data and provides the updated data to an input of the dual port memory for writing back into the address corresponding to the received parameter value. A first port of the dual port memory is utilised as the output of the dual port memory coupled to the input of the updating element on a first clock cycle of the dual port memory, and a second port of the dual port memory is normally utilised as the input of the dual port memory coupled to the output of the updating element on a second clock cycle, the next address being accessed via the first port on the second clock cycle. A comparator receives the parameter value on the first clock cycle of the dual port memory and a next received parameter value on a second clock cycle, and provides a match signal if the received parameter value and the next received parameter value are the same. The match signal is utilised to enable the first port of the dual port memory to be used as the input for the second clock cycle so that the data updated by the updating element on the first clock cycle is provided at the first port rather than the second port and is therefore correctly provided to the input of the updating element on the second clock cycle.
摘要翻译：以与双端口存储器的时钟频率基本相同的数据采样率来更新双端口存储器。双端口存储器存储与数据样本流中的每个不同参数值有关的数据，并且从对应于接收到的参数值的存储器中的地址提供存储的数据。更新元件更新存储的数据并将更新的数据提供给双端口存储器的输入，以便写回到与所接收的参数值对应的地址中。双端口存储器的第一端口被用作在双端口存储器的第一时钟周期耦合到更新元件的输入的双端口存储器的输出，并且双端口存储器的第二端口通常用作所述双端口存储器的输入在第二时钟周期耦合到所述更新元件的输出，所述下一个地址在所述第二时钟周期经由所述第一端口访问。比较器在第二时钟周期中接收双端口存储器的第一时钟周期上的参数值和下一个接收到的参数值，并且如果接收到的参数值和下一个接收到的参数值相同，则提供匹配信号。匹配信号用于使双端口存储器的第一端口用作第二时钟周期的输入，使得在第一时钟周期由更新元件更新的数据被提供在第一端口而不是第二端口端口，因此在第二时钟周期上正确地提供给更新元件的输入。

摘要： A method and apparatus for monitoring telecommunications network elements, especially where direct access to those network elements is not available. The invention allows a network manager to build and maintain significant relationship information, as well as model the state of network elements with a high degree of accuracy, but based only on the information contained within the transactions built from the network traffic which is being monitored. In particular, it allows the network manager to obtain the same results that would previously have required direct access to an operator's network elements.

摘要： In an MPLS network (100), one or more monitoring probes (10, 20) are arranged to monitor data traffic on a particular path formed of several links (50) in the network. The monitoring information from the probes (10, 20) is then sent to a Network Management module (110) via links (70) in a path through the network (100) that avoids, so far as possible, any links (50) in the path being monitored, as well as any links (60) in paths that are considered to be important due to having high priority or that would be adversely affected by the additional monitoring information.

摘要： The power of a digital signal such as an optical data stream is set via digital-to-analog converter (12) having a reference input (12a) for connection to a DC reference signal (14). The pilot tone is injected into the reference input (12a) of the digital-to-analog converter. In the place of a dual amplitude control (modulation current and pilot tone), the arrangement of the invention only requires a single control, thereby reducing cost, power consumption, microcontroller input/output activity, area occupation (PCB real estate) and failure rate.
