Abstract: In one embodiment, which may be implemented in either IP networks or MPLS networks, a tree of the network may be constructed at a source network device by sending only a single packet. The remaining network devices in the network replicate the packet so that a copy will reach each of the egress nodes. Along the way, identity information from each node or hop will be added to the replicated packets. As the egress nodes receive the packets, the egress nodes will each send a reply packet to the source network device. The reply packet includes a list of every hop on the path. The source network device is configured to construct a tree of the network based on the reply packets.

Abstract translation: 在可以在IP网络或MPLS网络中实现的一个实施例中，可以通过仅发送单个分组来在源网络设备处构造网络的树。 网络中剩余的网络设备复制数据包，以便副本将到达每个出口节点。 一路上，每个节点或跳点的身份信息将被添加到复制的数据包中。 当出口节点接收到分组时，出口节点将各自向源网络设备发送应答分组。 应答报文包含路径上每一跳的列表。 源网络设备被配置为基于应答分组来构建网络树。
