    • A technique for detecting a loop between network devices such as customer and carrier edge devices involves counting the number of media access control (MAC) address moves that occur at a device and comparing the number of MAC address moves to a pre-established MAC move threshold. The technique includes artificially accelerating the MAC move count related to a MAC address when the MAC address is moving between a set of ports at which the MAC address was previously found. The MAC move count is artificially accelerated because movement of a MAC address between a set of ports at which the MAC address was previously found is a strong indication of loop. The MAC move count is artificially accelerated by weighting the MAC move count once it has been determined that a MAC is moving between a set of ports at which the MAC address was previously found.
    • 用于检测诸如客户和载波边缘设备的网络设备之间的循环的技术涉及对在设备处发生的媒体访问控制(MAC)地址移动的数量进行计数,并将MAC地址移动的数量与预先建立的MAC移动阈值进行比较 。 当MAC地址在先前发现MAC地址的一组端口之间移动时,该技术包括人为地加速与MAC地址相关的MAC移动计数。 MAC移动计数被人为加速,因为在先前发现MAC地址的一组端口之间的MAC地址的移动是循环的强指示。 一旦确定MAC正在先前发现MAC地址的一组端口之间移动,则通过对MAC移动计数进行加权来人为加速MAC移动计数。

    • A method and system is provided for distributed wireless access. The system includes an access concentrator and a plurality of antenna modules. The antenna modules are spread across a campus and are coupled to the access concentrator via network wiring. Each antenna module includes an antenna to receive and transmit signals. When incoming signals are received at the antenna, the signals are converted from a radio frequency to a lower frequency. The converted signals are then digitized. The digital signals are then processed by digital signal processing resources at the access concentrator. Then, the processed signals are forwarded out of the corresponding ports to a LAN switch.
    • 提供了一种用于分布式无线接入的方法和系统。 该系统包括接入集中器和多个天线模块。 天线模块分布在校园内,并通过网络线路耦合到接入集中器。 每个天线模块包括用于接收和发送信号的天线。 当在天线处接收到输入信号时,信号从射频转换成较低的频率。 然后转换的信号被数字化。 然后,数字信号由接入集中器处的数字信号处理资源处理。 然后,处理的信号从对应的端口转发到LAN交换机。

    • A first addressing message is received at a first switch in a network fabric indicating that a first virtual machine has undergone migration from connection to a first virtual switch at a first server to connection to a second virtual switch at a second server. A route advertisement message is then transmitted from the first switch to at least a second switch in the network fabric. This route advertisement is configured to cause the second switch to transmit a second addressing message to a second virtual machine connected to the first virtual switch. The second addressing message provides the second virtual machine with updated addressing information for the first virtual machine. A third addressing message is also transmitted from the first switch to the first virtual machine to provide the first virtual machine with updated addressing information for the second virtual machine.
    • 在网络结构中的第一交换机处接收到第一寻址消息,指示第一虚拟机已经从第一服务器处的连接迁移到第一虚拟交换机,以连接到第二服务器处的第二虚拟交换机。 然后,路由通告消息从第一交换机发送到网络结构中的至少第二交换机。 该路由通告被配置为使得第二交换机向连接到第一虚拟交换机的第二虚拟机发送第二寻址消息。 第二寻址消息为第二虚拟机提供用于第一虚拟机的更新的寻址信息。 第三寻址消息也从第一交换机发送到第一虚拟机,以向第一虚拟机提供用于第二虚拟机的更新的寻址信息。
