What is TTL (Time To Live)?
When you download a file, it is broken into many packets of data before it is sent to your computer (where it is then reassembled). Not all of these data packets use the same path along the Internet to your computer. Some packets may not arrive in a reasonable length of time and some may even become lost. An arrangement of incorrect routing tables could cause a packet to loop in the network endlessly and congest the network.
Because of this, packets of data are set with an "expiration date" and will be discarded after a certain number of hops (a hop occurs every time a packet is sent from one computer to the next along a path). TTL stands for Time To Live. After a packet is discarded, your computer will have to request the missing packet(s) again from the originator.
Setting your TTL too low would make it impossible for some packets to reach their destination. Setting it too high would cause the network to become congested. This value is set automatically by the QuickOptimization feature, although expert users and network engineers are free to make their own adjustments on the Detailed Optimization tab.
