    • Methods and systems for reroute and generation of backward routing information are provided. When an originator node wants to transmit a packet to a destination node and cannot transmit the packet to a next node recorded in a routing table, the originator node records a backward packet tag and information of the originator node into the packet, and transmits the edited packet to a backup node recorded in the routing table. The backup node retrieves a backward routing table in response to the backward packet tag to see whether a forwarding node corresponding to the originator node and the destination node is a backward routing terminal. If not, the backup node transmits the packet to the forwarding node. If so, the backup node removes the backward packet tag and the information of the originator node from the packet, and transmits the packet to the forwarding node.
    • 提供了重新路由和生成后向路由信息的方法和系统。 当发起者节点想要向目的地节点发送分组,并且不能将分组发送到记录在路由表中的下一个节点时,发起者节点将反向分组标签和发起者节点的信息记录到分组中,并发送编辑的 分组到记录在路由表中的备份节点。 备份节点响应于反向分组标签检索后向路由表,以查看对应于始发者节点和目的地节点的转发节点是否是后向路由终端。 如果没有,则备份节点将数据包发送到转发节点。 如果是,则备份节点从分组中去除反向分组标签和发起者节点的信息,并将该分组发送到转发节点。
