time to live (TTL) TTL is used to manage the lifecycle of data stored in Tablestore data tables.Tablestoreautomatically deletes data whose TTL is expired. This helps you reduce storage space and save storage costs. The TTL of data is specified in seconds. For more information, seeData versio...
the gateway or next hop that the device should use to reach each destination, and other related information such as the interface used to reach each destination. The route table is used by the device to determine the best path for routing traffic to its destination...
If it is, the device forwards the packet according to the IP forwarding process. Otherwise, the device adopts the MPLS forwarding process for the packet. Specifically, it searches for the outbound interface, next hop, outgoing label (e.g., Y), and label operation (e.g., push label Y) ...
Time to live (TTL) determines how long to cache either a query or content. Learn how time to live (TTL) works & how it impacts your website.
will proceed through the process of getting the IP address for the user. The recursive DNS server's next step is to store the IP address for a specific amount of time. This period of time is defined by the person who owns the domain using a setting referred to as time to live (TTL)...
Traceroute sends out a series of ICMP Echo Request packets with increasing TTL values. With the initial TTL value typically set to 1, when the first packet is sent, it reaches the first router encountered on the path. The TTL is decremented to zero. The router discards the packet and send...
