Claim 7:
8. A device for determining a time-to-live (“TTL”) value of a node in a multi-hop network, comprising:
a first sub-processor configured to identify a set of nodes each having an unknown TTL value in the multi-hop network, and configure one node from the set of nodes as a target node;
a second sub-processor configured to send a packet for requesting a node state to a node in the multi-hop network based on a currently planned TTL value, acquire the node state fed back by the node, and determine a unicast address feedback list based on the node state; and
a third sub-processor configured to match unicast addresses in the unicast address feedback list and unicast addresses in a unicast address scan list corresponding to a target node to obtain a matching result, and determine a TTL value of the target node based on the matching result;
wherein the target node is a node in the multi-hop network, and the unicast address scan list is a list of addresses of all nodes in the multi-hop network that are in a working state detected by the target node.
