    • The present invention minimizes the amount of traffic that traverses the fabric in support of the cache coherency protocol. It also allows rapid transmission of all traffic associated with the cache coherency protocol, so as to minimize latency and maximize performance. A fabric is used to interconnect a number of processing units together. The switches are able to recognize incoming traffic related to the cache coherency protocol and then move these messages to the head of that switch's output queue to insure fast transmission. Also, the traffic related to the cache coherency protocol can interrupt an outgoing message, further reducing latency. The switch incorporates a memory element, dedicated to the cache coherency protocol, which tracks the contents of all of the caches of all of the processors connected to the fabric. In this way, the fabric can selectively transmit traffic only to the processors where it is relevant.
    • 本发明最大限度地减少了支持高速缓存一致性协议的通过结构的业务量。 它还允许与高速缓存一致性协议相关联的所有业务的快速传输,以便最小化等待时间并最大化性能。 织物用于将多个处理单元互连在一起。 交换机能够识别与缓存一致性协议相关的传入流量,然后将这些消息移动到该交换机的输出队列的头部以确保快速传输。 此外,与缓存一致性协议相关的流量可以中断外发消息,进一步减少延迟。 该交换机包含专用于高速缓存一致性协议的存储器元件,其跟踪连接到该结构的所有处理器的所有高速缓存的内容。 以这种方式,结构可以选择性地将流量传输到与其相关的处理器。

    • The invention utilizes a separate queue per output port as implemented in the traditional simple queuing schemes of the prior art. Further, it also uses the information found in the packet header to determine the output port and the next output port. Based on this information, it utilizes queues dedicated to congested flows, or “Congested Flow” queues. When the switch determines that, based on the first output port and the second subsequent output port, a packet in the output queue is destined for a congested path, it sets the offending packet aside in a Congested Flow queue, thereby allowing other packets destined for the first output port to continue to be transmitted. In this way, the HOL blocking issue is addressed, without the need for a significantly increased number of output queues.
    • 本发明利用在现有技术的传统简单排队方案中实现的每个输出端口的单独队列。 此外,它还使用分组报头中找到的信息来确定输出端口和下一个输出端口。 基于此信息,它利用专用于拥塞流或“拥塞流”队列的队列。 当交换机确定基于第一输出端口和第二后续输出端口时,输出队列中的数据包将发往拥塞路径,它将违规数据包置于拥塞流队列中,从而允许其他数据包发往 第一个输出端口继续传输。 以这种方式,解决了HOL阻塞问题,而不需要显着增加输出队列数量。

    • A line guiding assembly is provided comprising a line assembly including one or more lines and having a first length and a second length extending parallel thereto. The length ends are connected to a stationary element and to a reciprocable element in the line longitudinal direction, respectively. The two lengths merge with each other in loop-shaped manner in a bending portion located therebetween. The line assembly, at least in the portion in which the two lengths are facing each other, is provided with a material having good slidability for sliding on each other. A roller is introduced in the bending portion in such a manner that, upon movement of the reciprocable element, the line assembly performs a rolling motion on the roller.
