TTLi

TTLi is an acronym used in several domains to denote different terms, and there is no single, universally recognized meaning. The intended meaning of TTLi is typically inferred from the context in which it appears.

In information technology and networking, TTLi is occasionally used to reference concepts related to time-to-live (TTL) management. Common variants include Time-To-Live Indicator and Time-To-Live Information, referring to metadata or mechanisms that specify how long a data item, packet, or cache entry remains valid before expiring.

In research and vendor documentation, TTLi may appear as domain-specific terms that reflect project names, interfaces, or internal standards. Because TTLi lacks a formal standard, definitions can vary between organizations and publications.

See also TTL, time-to-live; caching and expiration, to provide related concepts that often accompany discussions where TTLi is encountered.
