    • A method is provided in order to determine connection topology of a home network. The main idea of the present invention is to send out a topology determination message on each link of the network, wherein the topology determination message is constituted of two consecutive packets, first one being a broadcast packet with a predetermined payload that identifies it as a topology determination packet, and second one being a unicast packet with the same content and a non-existent destination MAC address. If a node receives both the broadcast and unicast packet from a sending node, the sending node is determined to be on the same physical link with said receiving node and the MAC address of the sending node is added into a local link nodes list of said receiving node, otherwise if said receiving node receives only the broadcast packet from the sending node, the send node is determined not to be on the same physical link with said receiving node.
    • 提供了一种方法来确定家庭网络的连接拓扑。 本发明的主要思想是在网络的每个链路上发送拓扑确定消息,其中拓扑确定消息由两个连续的分组组成,第一个是具有预定有效载荷的广播分组,将其识别为拓扑 确定分组,第二个是具有相同内容和不存在的目的地MAC地址的单播分组。 如果节点从发送节点接收到广播和单播分组,则发送节点被确定为与所述接收节点处于相同的物理链路,并且发送节点的MAC地址被添加到所述接收的本地链路节点列表中 否则如果所述接收节点仅从发送节点接收到广播分组,则确定发送节点不与所述接收节点处于相同的物理链路上。
