    • A data network includes a plurality of end systems; a plurality of line data buses connected to the end systems; and a plurality of switches connected to the line data buses and to other switches via trunk data buses to define a star topology. The switches and end systems are configured to operate asynchronously. Each switch includes a number of packet schedulers for managing the transmission of received data flow. A number of effective line rate utilization mechanisms are each associated with a respective packet scheduler for providing the service rate of that packet scheduler. Switch egress ports transmit the received data flow. Each switch egress port has a defined configured effective transmission rate. Each effective line rate utilization mechanism reduces the utilization rate to the defined configured effective transmission rate.
    • 数据网络包括多个终端系统; 连接到端系统的多条线数据总线; 以及多个开关,其通过中继线数据总线连接到线路数据总线和其它交换机,以定义星形拓扑。 交换机和终端系统被配置为异步运行。 每个交换机包括用于管理接收的数据流的传输的多个分组调度器。 多个有效的线路利用率机制各自与相应的分组调度器相关联,用于提供该分组调度器的服务速率。 交换出口端口发送接收到的数据流。 每个交换机出口端口具有定义的配置的有效传输速率。 每个有效的线路利用率机制将利用率降低到规定的有效传输速率。

    • A ‘per flow’ flow monitor is operatively associated with each ingress port of the switch of the data network, for monitoring the arrival data flow on each flow in defined traffic constraint envelopes containing frames. An eligibility time computation mechanism computes an eligibility time at which arriving frames on each flow will be conformant to the defined traffic envelope to the ingress port given past frame arrivals on that same flow. A holding mechanism holds the arriving frames on each flow until the eligibility time is reached. A release mechanism releases the arriving frames on a flow at the eligibility time. The flow monitor, computation mechanism, holding mechanism, and release mechanism cooperate to provide an ‘per flow’ traffic shaping function in conformance with delay and delay-jitter bound, frame loss probability, and bandwidth provisioning requirements, thus allowing the switch to enforce the traffic constraint envelope for each flow.
    • “每流”流量监视器与数据网络的交换机的每个入口端口可操作地相关联,用于监视包含帧的定义的业务约束包络中的每个流的到达数据流。 资格时间计算机制计算出每个流程上的到达帧将符合定义的流量包络的资格时间,以确定给定过去帧流到同一流程的入口端口。 保持机构将到达的帧保持在每个流程上,直到达到资格时间。 释放机制在合格时间内将流动的框架释放。 流量监测器,计算机制,保持机制和释放机制协同提供符合延迟抖动约束,帧丢失概率和带宽配置要求的“每流”流量整形功能,从而允许交换机强制执行 每个流量的流量约束包络。

    • Two design variations which allow multiple processors to start up using a single ROM are disclosed. In each design, a single, primary processor is allowed to perform a complete POST while the remaining, secondary processors are directed in the course of their POST to perform a more limited initialization sequence. At power on, the primary processor begins a normal POST, while the secondary processors are held until a vector is placed into a redirection vector location. Each secondary processor is then subsequently started, using its own initialization code located at the address indicated by the redirection vector. The first technique is applicable to general multiprocessor systems because the implementation of this design can be run either from external software or from an addition to the operating system of the particular machine on which it is being used. The second technique is more specifically oriented to a particular system, and includes the use of an identity register to differentiate between primary and secondary processors.
    • 公开了允许使用单个ROM启动多个处理器的两种设计变型。 在每个设计中,允许单个主处理器执行完整的POST,而剩余的辅助处理器在其POST过程中被引导以执行更有限的初始化序列。 上电时,主处理器开始正常POST,而辅助处理器保持,直到向量放置到重定向向量位置。 然后,使用其位于由重定向向量指示的地址处的自己的初始化代码随后启动每个二级处理器。 第一种技术适用于一般的多处理器系统,因为这种设计的实现可以从外部软件运行,也可以从添加到正在使用它的特定机器的操作系统运行。 第二种技术更具体地针对特定系统,并且包括使用身份寄存器来区分主处理器和辅助处理器。
