TTL (Time To Live)

contribute to overall network congestion. Over time, the TTL field has been redefined to indicate, as an option, the number of hops (i.e., routers) through which the packet travels. In effect, the TTL is a hop count, anyway.The default TTL is 64. See also datagram, gateway, header, host, Internet, IPv4, MPLS, and packet.
