    • A method and apparatus for managing the flow of data within a switching device is provided. The switching device includes network interface cards connected to a common backplane. Each interface card is configured to support the maximum transfer rate of the backplane by maintaining a “pending” queue to track data that has been received but for which the appropriate routing destination has not yet been determined. The switching device includes a switch controller that maintains a central card/port-to-address table. When an interface card receives data with a destination address that is not known to the interface card, the interface card performs a direct memory access over a bus that is separate from the backplane to read routing data directly from the central table in the switch controller. Each interface card builds and maintains a routing information table in its own local memory that only includes routing information for the destination addresses that the interface card is most likely to receive.
    • 提供一种用于管理切换装置内的数据流的方法和装置。 交换设备包括连接到公共背板的网络接口卡。 每个接口卡被配置为通过维持“挂起”队列来支持背板的最大传输速率来跟踪已经接收到但是尚未确定适当的路由目的地的数据。 开关装置包括维持中央卡/端口到地址表的开关控制器。 当接口卡接收到具有接口卡不知道的目的地地址的数据时,接口卡通过与背板分离的总线执行直接存储器访问,以直接从交换机控制器中的中央表读取路由数据。 每个接口卡在其本地存储器中构建并维护路由信息表,其中仅包括接口卡最可能接收的目的地地址的路由信息​​。

    • The current invention is a tonneau cover that provide a barrier that covers the bed of a truck in order to conceal cargo. These covers are often soft, which can be easily broken into. The present invention offers a device that provides additional rigid protection for soft tonneau covers, thereby increasing the security of a truck bed. Additionally, use of the present invention can improve durability of existing covers as well as limit the wear and tear of the cover. This invention could also feature a system of hinges for ease of use. Further, the present invention can be offered in different colors in order to match the color of any vehicle for an enhanced appearance.

    • A method and apparatus for controlling data flow within a switching device are provided. The switching device includes a cell-switched backplane. Both packet switched and cell switched network interface cards may be coupled to the cell-switched backplane. A destination tag is created for each unique destination port and for each unique set of destination ports. The destination tags are used to index a master destination tag table. The entry of the master destination tag table that corresponds to a given destination tag includes a destination mask that indicates which ports are destination ports the given destination tag. Local tables are built and maintained within each network interface card based on the information contained in the master destination tag table. When a network interface receives data from an external device, the network interface determines the destination tag associated with the data. Once the destination tag is determined, it is used as an index to the locally stored tables to determine whether the data should be forwarded to any local ports, and whether the data should be sent over the cell-switched backplane to other network interfaces within the switching device. When a network interface receives data over the backplane, the network interface uses the destination tag as an index to a locally stored table to determine to which local ports the data should be sent. Tables also establish correlations between destination tags and control information for converting data between packets and cells.
    • 提供一种用于控制切换装置内的数据流的方法和装置。 交换设备包括小区交换背板。 分组交换和小区交换网络接口卡都可以耦合到小区交换背板。 为每个唯一目标端口和每个唯一的目标端口集创建一个目标标签。 目的地标签用于索引主目标标签表。 对应于给定目的地标签的主目的地标签表的条目包括目的掩码,其指示哪些端口是给定目的地标签的目的地端口。 根据主目标标签表中包含的信息,在每个网络接口卡内构建和维护本地表。 当网络接口从外部设备接收数据时,网络接口确定与数据相关联的目的地标签。 一旦确定了目的地标签,就将其用作本地存储表的索引,以确定数据是否应转发到任何本地端口,以及数据是否应通过小区交换背板发送到其中的网络接口 开关装置。 当网络接口通过背板接收数据时,网络接口使用目标标签作为本地存储表的索引,以确定应向哪些本地端口发送数据。 表格还建立了目标标签和控制信息之间的相关性,以便在数据包和单元之间转换数据。
