摘要： A policing method is proposed policing an aggregate ATM cell stream (IN) consisting of both high and low priority cells. The method consists in policing the aggregated stream as a whole whilst also policing separately a substream formed by the high priority cells as prescribed by ITU-TS recommendation I.371.
The present policing method always inserts a high priority cell satisfying the last mentioned separate policing step into the output stream (OUT) regardless of the result of the first mentioned aggregate policing step. In order to keep a good performance for the method, the predicted arrival time used in this aggregate policing step is however also updated for such a high priority cell which does not conform to this aggregate policing step. The latter requires a modification of the known and commonly used Virtual Scheduling Algorithm.摘要翻译： 提出了一种策略方法，对由高优先级和低优先级单元组成的聚合ATM信元流（IN）进行监管。 该方法在于对整个聚合流进行整体监管，同时还对由ITU-TS建议I.371规定的高优先级小区形成的子流分别进行监管。 无论首先提到的聚合控制步骤的结果如何，本调节方法总是将满足最后提到的单独控制步骤的高优先级单元插入到输出流（OUT）中。 为了保持该方法的良好性能，然而，对于不符合该聚合管制步骤的高优先级小区，也在该聚合管制步骤中使用的预测到达时间被更新。 后者需要修改已知和常用的虚拟调度算法。

摘要： A bursty traffic multiplexing arrangement (A) includes a multiplexing unit (MUX) to multiplex a plurality of bursty input flows (IF1, ... , IFI, ... , IFN) into an output flow (OF).
Congestion due to insufficient throughput capacity of the multiplexing unit (MUX) is avoided by incorporating an input shaping device (ISDI) for each input (MII) of the multiplexing unit (MUX). Data elements constituting such an input flow (IFI) are stored in an input buffer (IBI) which forms part of the corresponding input shaping device (ISDI), and are applied to the multiplexing unit (MUX) at a rate (BI) which does not exceed a predetermined maximum input buffer reading rate (BIMAX) associated to this input buffer (IBI).
Furthermore, via feedback input flow rate control information (IFRI), the input flow rates (A1, ..., AI, ... , AN) can be controlled to thereby avoid input buffer overload.摘要翻译： 突发业务复用布置（A）包括复用多个突发输入流（IF1，...，IFI，...，IFN）到输出流（OF）中的复用单元（MUX）。 通过为复用单元（MUX）的每个输入（MII）并入输入整形设备（ISDI）来避免由于复用单元（MUX）的吞吐量不足导致的拥塞。 构成这样的输入流（IFI）的数据元素被存储在形成相应输入整形设备（ISDI）的一部分的输入缓冲器（IBI）中，并以一个速率（BI）被施加到复用单元（MUX） 不超过与该输入缓冲器（IBI）相关联的预定最大输入缓冲器读取速率（BIMAX）。 此外，通过反馈输入流量控制信息（IFRI），可以控制输入流量（A1，...，AI，...，AN），从而避免输入缓冲区过载。

摘要： The policing device verifies at a predetermined location of a communication system whether a cell stream transmitted over that communication system satisfies a negotiated cell interarrival time and a negotiated cell delay variation and takes adequate actions. The verification is performed according to an algorithm including the steps of comparing for each cell of the cell stream and at the predetermined location the current arrival time of the cell with a predicted arrival time and discarding the cell if that predicted arrival time is larger than the sum of the present arrival time and an additional time interval. When simultaneously the cell is discarded and the additional time interval is smaller than the negotiated cell interarrival time, the predicted arrival time is adapted and the additional time interval is increased to a value having an upper limit equal to the negotiated cell interarrival time, whereas when the predicted arrival time is smaller than or equal to the current arrival time the additional time interval is decreased to a value having a lower limit equal to the negotiated cell delay variation.

摘要： A shaping method is proposed in which cells (U1-U7, 01-06) of a cell stream (CS1) are mutually delayed to obtain a shaped cell stream (CS2). For this a shaping delay is used which depends upon the type of the cells which are so delayed in order for consecutive user cells (U1-U2, U2-U3, ...) to be mutually delayed over the inverse (TU) of the peak cell rate negotiated for these user cells (U1-U7).
The above is obtained by making this shaping delay equal to the above inverse when adjacent cells are user cells (U1-U2), to a fraction (TU/3) of this inverse when the second one of these adjacent cells is an operation and maintenance or OAM cell (01-07) and to the difference between the above inverse and the number of consecutive OAM cells inbetween two user cells (U5-U6) times the above fraction if the first one of said adjacent cells is an OAM cell (03) whilst the second one is a user cell (U6).摘要翻译： 在其中细胞（U1-U7，O1-O6）的细胞流（CS1）是相互延迟以获得成形单元流（CS2）的成形方法，提出了 对于这种成形延迟用于的，在其上，以便在顺序连续用户信元（U1-U2，U2-U3，...）的延迟单元的类型取决于要被相互延迟过的倒数（TU） 协商的用于合成的用户信元（U1-U7）峰值信元速率。 以上是通过使该成形延迟等于上述逆当相邻小区的用户信元（U1-U2），在馏分而得到（TU / 3）这个逆当合成相邻小区中的第二个是操作和维护的 或OAM信元（O1-O7）和上述逆和连续OAM信元的其间两个用户单元（U5-U6）倍以上分数如果所述相邻单元的第一个是一个OAM单元的数量之间的差（03 ），而第二个是一个用户信元（U6）。

摘要： 5 n7 The shaping arrangement includes a time parameter assignment unit (TAU) coupled between an input terminal (IN1/16) of an information packet switching system and a corresponding input (SIN1/16) of a switching unit (SU) of that switching system and, a filter circuit (FC) and a buffer circuit (FC) coupled in cascade between an output (SOUT1/16) of the switching unit (SU) and an output terminal (OUT1/16) of the switching system.
The time assignment unit (TAU) calculates, according to a predetermined algorithm and for each information packet applied to it, the value of a time parameter as a function of the instant in time at which that information packet is applied to the input terminal of the system and inserts the calculated value in the information packet. Thereafter the information packet is switched by the switching unit (SU) to the above mentioned output (SOUT1/16) and thus to the filtering circuit (FC). The latter circuit applies the information packet to the buffer circuit (BC) or not depending on the result of the application of a filtering algorithm to that information packet. The filtering algorithm uses the value of the time parameter inserted in the information packet.
The buffer circuit buffers the information packet before providing it to the output terminal during a time interval which is such that the total time interval indicated by the difference between the instant in time at which the information packet is supplied to the output terminal and the value of the time parameter included in the packet has a predetermined constant value.摘要翻译： 整形装置包括耦合在信息分组交换系统的输入端（IN1 / 16）与该交换系统的交换单元（SU）的相应输入（SIN1 / 16）之间的时间参数分配单元（TAU） 串联耦合在开关单元（SU）的输出（SOUT1 / 16）与开关系统的输出端（OUT1 / 16）之间的滤波电路（FC）和缓冲电路（FC）。 时间分配单元（TAU）根据预定的算法和对其应用的每个信息分组，计算作为该信息分组被应用于该信息分组的输入终端的时刻的函数的时间参数的值 系统，并将计算的值插入到信息包中。 此后，信息包由切换单元（SU）切换到上述输出（SOUT1 / 16），从而被切换到滤波电路（FC）。 后一电路根据向该信息包应用滤波算法的结果将信息包应用于缓冲电路（BC）。 过滤算法使用插入到信息包中的时间参数的值。 缓冲电路在将信息包提供给输出终端之前将其提供给输出终端的时间间隔内缓冲信息包，使得由将信息包提供给输出终端的时刻之间的差异指示的总时间间隔和 分组中包含的时间参数具有预定的常数值。

摘要： A policing device is proposed in which a plurality of parallel police processors (PP1, PP2) are included each of which implements a Modified Virtual Scheduling Algorithm and is so able to derive for a cell for which it is activated by an enabling circuit (EC) a conformance signals (CS1, CS2). An arbitration module (AM) generates from the latter signals, a plurality of which may be provided per cell of the input ATM stream (IN), a discard signal (DS) indicating wether or not such a cell may be inserted into an output stream (OUT) by a discard circuit (DC) as well as feedback signals (FS1, FS2) which indicate to a corresponding processor whether or not to carry out an already prepared update of a predicted arrival time used in the above mentioned algorithm.
The architecture of the present policing device is very generic in that it allows implementation of any policing method by straightforwardly adapting the arbitration module and the enabling circuit.摘要翻译： 提出了一种管制设备，其中包括多个并行警察处理器（PP1，PP2），每个并行警察处理器（PP1，PP2）中的每一个都实现修改的虚拟调度算法并且能够针对其由启用电路（EC）激活的单元导出， 一致性信号（CS1，CS2）。 仲裁模块（AM）根据后者的信号产生多个输入ATM流（IN）的每个单元，丢弃信号（DS）指示是否这种单元可以被插入到输出流 （DC）以及向相应的处理器指示是否执行上述算法中使用的预测到达时间的已经准备好的更新的反馈信号（FS1，FS2）发送（OUT）。 本监控设备的体系结构非常通用，因为它允许通过直接适应仲裁模块和启用电路来实现任何监管方法。

摘要： The connectionless server is able to transfer messages constituted by information packets over a connection oriented switching network ATM in a connectionless way. It includes a plurality of processing modules TLK1 to TLKm, CLSP1 to CLSPn and CLPR1 to CLPRp, which perform respective predetermined actions on the information packets in a predetermined sequence and thereafter transfer these packets over the ATM network. The modules communicate with each other over a switching means MPSR which can be the ATM network. The time interval needed to perform the mentioned actions is at most equal to the minimum inter arrival time between two successive packets at the server. As a result the packet are handled on the fly.
