When I do a ping, I can see the TTL value for each packet. For every router that I insert in between my computer and the router that connects to the internet, the TTL value goes down by one. However, inserting a switch or a hub does not have any effect on the TTL value. TTL value dosent decremented by a switch. A router in path decrments it. TTL field in IP datagram is set by the sender and decremented by every router on the route to its destination.

The TTL (Time To Live), representing the effective scope of multicast distribution, is decremented each time the signal passes through a router . When the value reaches 0, the signal can no longer be distributed. For example, if TTL is set to [1], multicast distribution is confined to the local segment only and. May 06, 2019 · In any case, based on this logic, in theory the maximum time a packet can exist in the network is 4.25 minutes (255 seconds).
