Due to their stateless nature the UDP packets are never considered lost i.e nobody is going to go looking for them to retransmit. However they do have a Time To Live value. once this is expired the packet is considered out of date but wont be re-requested
Packets with expired TTL can't be re-requested for being "out of date" since they don't reach the server.
the server dosen't request the retransmit when a packet dies of TTL, the client does; because he gets an ICMP message from the HOP the discarded the packet informing him the the packet was discarded.
As for lost packets, are you sure that the HLDS doesn't use a transmit protocol over UDP?
would probably take longer to retransmit the lost packet (with, by then, outdated information) then to just leave it lost and continue with packets containing right information.
