    • An ATM switch with a switch queuing system which minimizes cell loss for bursty traffic, while avoiding delay for time-critical. The switch has a plurality of input ports and a plurality of output ports, a switch fabric transmitting cells from the input ports to the output ports, and a backpressure signal circuit connected between each output buffer of each output port and each input buffer of each input port. Each input port has an input buffer holding ATM cells when the cells arrive faster from the port's input channel than the input port can transmit. The input port transmits cells from its input buffer responsive to a plurality of priority levels. Each output port has an output buffer holding cells when the cells arrive faster from the input ports than the output port can transmit. The output port also transmits cells from its output buffer responsive to a plurality of priority levels. The backpressure signal circuit sends a signal from a congested output buffer through the switch fabric to those input port buffers which had immediately transmitted a cell to the output buffer so that the input port buffers cease transmission. In this manner, the ATM switch drops cells on a per-connection basis, rather than on cell priority level.
    • 一种带有交换机排队系统的ATM交换机,可以最大限度地减少突发流量的信元丢失,同时避免对时间要求严格的延迟。 开关具有多个输入端口和多个输出端口,交换结构将信元从输入端口传输到输出端口,以及背压信号电路连接在每个输出端口的每个输出缓冲器与每个输入端口的每个输入缓冲器之间 港口。 每个输入端口有一个输入缓冲区,当信元从端口输入通道到达的速度比输入端口可以传输的速度快时,该缓冲区保存ATM信元。 响应于多个优先级,输入端口从其输入缓冲器发送信元。 每个输出端口都有一个输出缓冲器,用于在单元从输入端口到达速度快于输出端口传输速度时保持单元。 响应于多个优先级,输出端口也从其输出缓冲器发送信元。 背压信号电路通过交换结构将来自拥塞输出缓冲器的信号发送到立即将一个单元传送到输出缓冲器的那些输入端口缓冲器,以便输入端口缓冲器停止传输。 以这种方式,ATM交换机在每个连接的基础上丢弃信元,而不是在小区优先级上。

    • PURPOSE: A VPI(Virtual Path Identifier) extension method for an ABR(Available Bit Rate) multipoint-to-point connection in an ATM network is provided to solve a problem of congestion control balance in an existing VC merging technique and the problem that many VPI/VCI tables are required in an existing VP merging technique. CONSTITUTION: The fourth exchange receives ATM cells, having an identical VPI value but different VCI values, from different sources through an ATM network(S1). The fourth exchange checks the MSB(Most Significant Bit) values of the VPI fields of the ATM cells and judges the connection type of the ATM cells(S2). In case that the MSB values of the VPI fields of the ATM cells is "0" which means that the connection type is a multipoint-to-point connection, the fourth exchange extracts the VPI value from each VPI field, extends each VPI value into a 16-bit value, and inserts each extended VPI value into each VCI field(S3). Then the fourth exchange extracts a VCI value from each VCI field, converts each VCI value into a 11-bit value using the multipoint-to-point VCI conversion information of the multipoint-to-point connection field of a VPI/VCI table, and inserts each converted VCI value into each VPI field(S4). Then the fourth exchange classifies the sources through the VCI values in the their respective VPI fields, executes cell interleaving at a merging point, and transmits the ATM cells to an identical destination source(S5).
    • 目的:提供ATM网络中ABR(可用比特率)多点到点连接的VPI(虚拟路径标识符)扩展方法,以解决现有VC合并技术中的拥塞控制平衡问题,以及许多 现有VP合并技术需要VPI / VCI表。 构成:第四个交换机通过ATM网络接收来自不同来源的ATM信元,具有相同的VPI值但不同的VCI值(S1)。 第四交换机检查ATM信元的VPI字段的MSB(最高有效位)值,并判断ATM信元的连接类型(S2)。 在ATM信元的VPI字段的MSB值为“0”,意味着连接类型为多点到点连接的情况下,第四交换机从每个VPI字段提取VPI值,将每个VPI值扩展为 一个16位值,并将每个扩展VPI值插入每个VCI字段(S3)。 然后第四交换机从每个VCI字段提取VCI值,使用VPI / VCI表的多点到点连接字段的多点到点VCI转换信息将每个VCI值转换成11位值,以及 将每个转换的VCI值插入每个VPI字段(S4)。 然后,第四交换机通过其各自的VPI字段中的VCI值对源进行分类,在合并点执行小区交织,并将ATM信元发送到相同的目的地源(S5)。

    • A traffic control apparatus for UBR service includes a first subscriber side connected to a second subscriber side through an ATM exchange. The first subscriber side includes an egress subscriber end which extracts UBR band information of the subscriber board of a second subscriber end fed back, and which determines the UBR band in accordance with the presence of cell traffic congestion and traffic loading state transmitted from the board of the second subscriber end. The apparatus further includes an ingress subscriber end which receives the UBR band information determined by the egress subscriber end, feeds back the UBR band information to the subscriber board of the second subscriber end, and processes a UBR user cell in accordance with the UBR band information of the second subscriber's board. The apparatus is advantageous in that it secures the quality of service of real-time traffic and utilizes any available real-time traffic band for UBR traffic, thereby preventing waste of bands and controlling UBR traffic more effectively.

    • PURPOSE: A method for controlling TCP(Transmission Control Protocol) congestion is provided to reversely apply an ECN(Explicit Congestion Notification) algorithm in a contact section between an ATM(Asynchronous Transfer Mode) network and a non-ATM network, under a TCP communication network environment on the ATM, thereby removing network congestion. CONSTITUTION: When a packet is received to a buffer, size of an average queue is calculated(S1). Whether the calculated size of the average queue is smaller than a minimum threshold is checked(S2). If so, the received packet is transmitted intactly(S3), and if not, whether the size of the average queue is larger than a maximum threshold is checked(S4). If so, the received packet is discarded(S5), and if not, an operation of marking the received packet is progressed according to probability values decided by the size and weight of the average queue, to generate a response packet(S6). An ECN echo flag is set in a TCP header of the response packet, to transmit the response packet to a TCP source(S7).

    • An ABR (Available Bit Rate) service engine in a packet switching system. A forward cell processing unit generates a first start signal and extracts CCR (Current Cell Rate) and MCR (Minimum Cell Rate) from a forward RM (Resource Management) cell, upon receipt of the forward RM cell. A locally bottlenecked virtual circuit number (|Q|) estimation unit determines whether (CCR-MCR) is less than ER (Explicit Rate) upon receipt of the first start signal, considers that the received RM cell contributes to |Q| if (CCR-MCR) is less than ER, accumulates the degree of contribution, and calculates |Q|. An ER engine calculates the ER upon receipt of a third start signal. A backward cell processing unit determines whether the ER calculated by the ER engine is less than the sum of ER and MCR extracted from a backward RM cell upon receipt of the backward RM cell, and writes the calculated ER in the backward RM cell if the calculated ER is less than the sum of ER and MCR. A timer feeds the second start signal to the |Q| estimation unit every first period and the third start signal to the ER engine every second period.

    • PURPOSE: The apparatus for removing lost packet data in order to prevent traffic congestion in an asynchronous transfer mode(ATM) system is provided to enable a stable ATM operation, and to guarantee the service with good quality for various types of service traffic, by preventing the traffic congestion in the system using minimum hardware logic.
