    • An imporved method and apparatus for making forwarding decisions in a switching device. The invention reduces the flooding of frames to particular network segments connected to the switch. To insure a device sees a frame addressed to it, if a switch does not know what segment a device address is connected to for a unicast frame, the switch typically floods the frame to all segments in the broadcast domain. This invention allows segments to be identified as having a predefined maximum number of device addresses that will be associated with it. When that number of addresses is already in the forwarding table the switch will not flood unicast frames to that segment since no more devices should be connected to that segment.
    • 一种用于在交换设备中进行转发决定的改进方法和装置。 本发明减少了帧连接到交换机的特定网段的洪泛。 为了确保设备看到寻址到其的帧,如果交换机不知道设备地址连接到单播帧的段,则交换机通常将该帧泛洪到广播域中的所有段。 本发明允许将段识别为具有与其相关联的预定义的最大数量的设备地址。 当转发表中已存在该地址的数量时,交换机将不会将该单播帧洪泛到该段,因为没有更多的设备应该连接到该段。
