1. one kind is used for comprising the following steps:

  • when data being divided into groups to carry out the heavy-route method of operating when link failure takes place network(a) route data grouping between headend node and nodes at ends;

    (b) link failure between described headend node of detection and the described nodes at ends before described packet arrives described nodes at ends;

    (c) the PLR node between described headend node and described nodes at ends receives described packet;

    (d) bypass tunnel by described PLR node returns described packet heavy-route to described headend node and heavy-route to described nodes at ends;

    And(e) send error message so that this headend node can use the local bypass tunnel to transmit subsequently packet to described nodes at ends from described PLR node to described headend node.
