Ensure packets reach destination within that time Discard packets that reach later than that time Prevent packets from looping indefinitely Limit the time for which a packet gets queued in intermediate routers Computer Networks iiith-pgee + – Tesla! 1.2k views comment Share Follow Print See all 2 Comments 2 2 Comments reply Tesla! commented Apr 22, 2018 reply Follow flag please refer below link for further discussion or comments https://gateoverflow.in/884/gate2006-5 1 1 replyShare Skan commented Apr 24, 2018 i reshown by Skan Apr 24, 2018 reply Follow flag Option 4 is : to improve throughput of network. TTL intention is to cause undeliverable datagrams to be discarded, and to bound the maximum datagram lifetime. 1. This is to control congestion in network and indirectly improving throughput. 2. and if congestion increases, increasing TTL by router has a direct positive impact on throughput in some cases. * As this comment only refers to this thread 0 0 replyShare Please log in or register to add a comment.
