发明名称 METHOD FOR PATH DETECTION AND NODE
摘要 <p>A method for path detection and a node. The method comprises: an initiating node sending an echo request packet to a detecting node carrying address list information the address list information comprising the address of the initiating node; the detecting node checking whether a node address in the address list information carried in the received echo request packet is reachable and using a found reachable address as a destination address of an echo replay packet; the detecting node adding address information thereof to the address list information carried in the echo replay packet to be returned. The node comprises a request packet sending module a searching module and a replay module. When the node does not have a reachable route of a head node other nodes on an LSP through which the packet passes may be found according to the address list information carried in the echo request packet and the echo replay packet is transferred to the initiating node by relaying thereby increasing the success rate of tracing a route.</p>
