    • The invention provides a method and switching device for configuring stack ports. A switching device in a stacking system searches in the neighbor information table to determine whether the neighbor ID carried in a stack link negotiation packet is contained in the table after it receives the stack link negotiation packet on one of its physical ports that is enabled with the stacking function. If the neighbor ID is contained in the table, the switching device adds the physical port to the stack port corresponding to the neighbor ID in the neighbor information table; if it is not contained in the table, the switching device creates a stack port not in use, creates a binding between the neighbor ID and the stack port, and adds the physical port to the stack port. The present invention can automatically configure stack ports, greatly reducing the configuration work of administrators, and avoiding stacking device faults caused by manual configuration errors at the same time.
    • 本发明提供了一种用于配置堆栈端口的方法和切换设备。 堆叠系统中的交换设备在邻居信息表中搜索到确定堆叠链路协商报文中携带的邻居ID是否在其物理端口之一上收到堆栈链路协商报文后被包含在表中, 堆叠功能。 如果表中包含邻居ID,交换设备将物理端口添加到邻居信息表中对应邻居ID的堆叠端口; 如果不包含在表中,交换设备创建一个未使用的堆叠端口,在邻居ID和堆叠端口之间创建绑定,并将物理端口添加到堆叠端口。 本发明可以自动配置堆叠端口,大大降低管理员的配置工作,避免同时由手工配置错误引起的堆叠设备故障。

    • A method for determining a derived geographic location of a target Internet host includes identifying plural landmark Internet hosts communicatively coupled with the target Internet host by a network. The method also includes measuring network latencies of probe packets transmitted to the target and landmark Internet hosts along different network pathways and calculating relative distances between the target Internet host and one or more of the landmark Internet hosts based on the network latencies. The method further includes comparing the relative distances to identify at least one of the landmark Internet hosts that is geographically closer to the target Internet host than one or more other landmark Internet hosts and determining the derived geographic location of the target Internet host based on a geographic location of the at least one of the landmark Internet hosts that is geographically closer to the target Internet host.
    • 用于确定目标因特网主机的导出地理位置的方法包括:通过网络识别与目标因特网主机通信耦合的多个地标性因特网主机。 该方法还包括测量根据不同网络路径传输到目标和地标Internet主机的探测包的网络延迟,并基于网络延迟计算目标Internet主机与一个或多个地标Internet主机之间的相对距离。 该方法还包括比较相对距离以识别与一个或多个其他地标性因特网主机在地理上更靠近目标因特网主机的地标性因特网主机中的至少一个,并且基于地理位置确定目标互联网主机的导出地理位置 地理位置上距离目标互联网主机更近的地标性互联网主机的位置。
