摘要： A network device includes one or more sprayers, multiple packet processors, and one or more desprayers. The sprayers receive packets on at least one incoming packet stream and distribute the packets according to a load balancing scheme that balances the number of bytes of packet data that is given to each of the packet processors. The packet processors receive the packets from the sprayers and process the packets to determine routing information for the packets. The desprayers receive the processed packets from the packet processors and transmit the packets on at least one outgoing packet stream based on the routing information.

摘要： The invention provides forced-air cooling to components mounted on circuit boards oriented in a side-to-side direction in a system. Airflow may enter and exit the system through the front and back (or vice-versa), rather than the sides of the system. In one embodiment, airflow entering the front of the system is re-directed in an upward direction, then split to form airflow branches traversing in a side-to-side direction. The airflow branches traverse across the surfaces of circuit boards, then are directed in an upward direction and out the back (or front) of the system. The airflow branches preferably move substantially the same volume of air per unit of time.

摘要： Mechanisms provide hosts such as servers and mobile devices with access to virtualized I/O resources including virtual Host Bus Adapters (vHBAs) and virtual Network Interface Cards (vNICs) over a wireless I/O interconnect. Host applications access virtualized I/O resources using virtual device drivers that communicate with virtualized I/O resources on an I/O director using a reliable communication protocol running over a wireless network. I/O data is throttled if necessary based on wireless network considerations.

摘要： Systems and methods, consistent with the present invention, provide a high-speed line interface for networking devices. Such an interface may be used in networking devices, such as routers and switches, for receiving data from, and transmitting data to, high-speed links, such as those lines carrying data at rates of 2.5 Gbit/sec, 10 Gbit/sec, and 40 Gbit/sec and more. In a preferred embodiment, the interface deserializes data from an incoming data stream onto a multi-line bus so that the data may be processed at a lower clock speed. Packets are extracted from the data on the multi-line bus and distributed among a plurality of switching/forwarding modules for processing.
摘要翻译：与本发明一致的系统和方法为网络设备提供高速线路接口。这样的接口可以用于诸如路由器和交换机之类的网络设备中，用于从高速链路接收数据，并向高速链路发送数据，例如以2.5Gbit / sec，10Gbit / sec的速率传送数据的那些线路，和40 Gbit /秒以上。在优选实施例中，接口将来自输入数据流的数据反序列化到多线总线上，使得可以以更低的时钟速度处理数据。从多线总线上的数据提取分组，并分配在多个交换/转发模块之间进行处理。

摘要： A traceless midplane contains substantially no traces, pins, or active components and includes a front portion and a back portion. The front portion includes first connectors. The back portion includes second connectors arranged in a grid pattern. Each of the second connectors includes electrically-conductive conduits that connect the second connector to a corresponding one of the first connectors through the midplane. The second connectors include data connection points, ground connection points, and clock connection points. At least some of the data connection points are separated from each other and from the clock connection points by the ground connection points.
