    • Methods, apparatuses and systems directed to a network traffic synchronization mechanism facilitating the deployment of network devices in redundant network topologies. In certain embodiments, when a first network device directly receives network traffic, it copies the network traffic and transmits it to at least one partner network device. The partner network device processes the copied network traffic, just as if it had received it directly, but, in one embodiment, discards the traffic before forwarding it on to its destination. In one embodiment, the partner network devices are operative to exchange directly received network traffic. As a result, the present invention provides enhanced reliability and seamless failover. Each unit, for example, is ready at any time to take over for the other unit should a failure occur. As discussed below, the network traffic synchronization mechanism can be applied to a variety of network devices, such as firewalls, gateways, network routers, and bandwidth management devices.
    • 针对网络流量同步机制的方法,装置和系统,便于在冗余网络拓扑中部署网络设备。 在某些实施例中,当第一网络设备直接接收网络业务时,它复制网络流量并将其发送到至少一个伙伴网络设备。 合作伙伴网络设备处理复制的网络流量,就像它直接接收到的,但是在一个实施例中,在将流量转发到其目的地之前丢弃该流量。 在一个实施例中,伙伴网络设备可操作以交换直接接收的网络业务。 因此,本发明提供增强的可靠性和无缝故障切换。 例如,如果发生故障,每个单元随时准备接管另一个单元。 如下所述,网络流量同步机制可以应用于各种网络设备,如防火墙,网关,网络路由器和带宽管理设备。

    • According to the present invention, there are provided a convertible bottomless file drawer and a file folder support assembly adapted to the bottomless file drawer for storing hanging file folders of different predetermined sizes. The bottomless file drawer includes a rectangular frame that includes a plurality of outside walls and a middle wall that includes a u-shaped channel having a bottom, and a first wall and a second wall dividing the frame into a plurality of compartments of a first predetermined dimension for supporting hanging file folders of a first predetermined size. The file folder support assembly including an inverse u-shaped channel having an inner tubular member disposed centrally therein, the tubular member of the inverse channel being adapted to seat in the u-shaped channel of the middle wall and the u-shaped channel of the middle wall being adapted to seat in the inverse channel, and a first projection extending horizontally from a first lower edge of the inverse channel, the projection having an outer wall, the top of which is coplanar with the plurality of outside walls of the frame, the outer wall reducing the first predetermined dimension of a first compartment to a second smaller predetermined dimension for supporting hanging file folders of a second predetermined size.
    • 根据本发明,提供了一种可转换无底文件抽屉和文件夹支撑组件,其适用于无底文件抽屉,用于存储不同预定尺寸的悬挂文件夹。 无底文件抽屉包括包括多个外壁的矩形框架和包括具有底部的U形通道的中间壁,以及将框架分成多个第一预定的隔室的第一壁和第二壁, 用于支撑具有第一预定尺寸的悬挂文件夹的尺寸。 所述文件夹支撑组件包括具有设置在其中间的内部管状构件的倒U形通道,所述反向通道的管状构件适于位于所述中间壁的所述U形通道中,并且所述U形通道 中间壁适于位于反向通道中,以及第一突起,其从所述反向通道的第一下边缘水平延伸,所述突起具有外壁,所述外壁的顶部与所述框架的所述多个外壁共面, 所述外壁将第一隔间的第一预定尺寸减小到第二较小的预定尺寸,以支撑具有第二预定尺寸的悬挂文件夹。
