What Is Time-To-Live?

By Ken Roberts 18 April, 2023 2 mins read

Time-tolive is a term that refers to the delay between packets sent through a network connection. It is used in ping and traceroute protocols. Using the Time-to-live, these protocols are able to determine the distance between two points. A ping sends only one packet. Traceroute sends multiple packets, each with a higher TTL. Each step on the route is responsible for returning an ICMP packet to the sender. Depending on how long it takes, the time taken to send the next package determines the time to go to the next hop.

Time-to-live

Time-to-live is a concept that limits the lifespan of data within a computer or network. Depending on the implementation, time-to-live may take the form of a timestamp or counter. It is discarded once the data reaches a certain timeframe or event count.

Networking often uses the time-to-live method to determine how long a record will remain cached. For example, an e-commerce site might update its HTML file displaying product prices every day. It is therefore important to establish a TTL on pages that include pricing information. Website performance can also benefit from a faster time-to-live.

Time-tolive index

Items inside a container that has a TTL value greater than "n" will expire within n seconds. The time-live index value of -1 will ensure that the containers don't expire. The TTL is the value that is specified on the container and not the items.

Schottky transistor

A Schottky transistor combines a transistor and a Schottky device. This diode keeps the transistor from overheating. It's also known as a Schottky clamped transistor. It's used in making switches and other devices requiring high-speed operation.

The Schottky transistor has two buried zones, an emitter zone and a base zone. The buried layer essentially acts as an insulator. The transistor's bulk resistance will be reduced by the buried layer.

ICMP

The ICMP ttl commands is used to monitor the Time To Live of a packet. TTL is an important field within IP protocol that affects a connection’s network performance. TTL changes may signify that a network has been changed. This could be due to routing reconvergence on a backbone or an end-device connected through a backup.

ICMP is a protocol that is used by computers to communicate over the Internet. It works with a range of protocols. Each protocol is designed to be different and ICMP has several different types and codes. Echo is one of them. You can test to see if ICMP messages are being received by running tcpdump or a ping.
