Claim 0:
1. A system for determining a time-to-live (“TTL”) value of a node in a multi-hop network, the system comprising:
a processor in a computer separate from the node, wherein the processor is 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; and
a target node, wherein the target node is configured to:
send a packet for requesting a node state to the node in the multi-hop network based on a currently planned TTL value,
acquire the node state fed back by the node,
determine a unicast address feedback list based on the node state,
match, unicast addresses in the unicast address feedback list and unicast addresses in a unicast address scan list corresponding to the target node to obtain a matching result, and
determine a TTL value of the target node based on the matching result;
wherein 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.
