rrl

Rrl, usually written as rrl or RRL, is an acronym that can refer to several distinct concepts depending on the context. There is no single universal definition, and readers should rely on surrounding text to determine the intended meaning.

One common usage is in academic writing, where RRL stands for Review of Related Literature (also seen as Review of Related Literature and Studies). This section surveys existing research relevant to a topic, identifies gaps, and establishes the theoretical framework and context for a study. It is a standard component of theses, dissertations, research proposals, and scholarly reports, helping to situate new work within the broader body of knowledge.

In the field of computer networking, RRL commonly denotes DNS Response Rate Limiting. This technique is employed to mitigate abuse and distributed denial-of-service attacks by capping the rate at which DNS servers send responses to similar queries. Implementation typically involves tracking query activity from individual clients or prefixes and applying a limit, with excess traffic being throttled or suppressed. RRL is part of broader efforts to improve the resilience and stability of DNS infrastructure and is discussed in server documentation and security best practices.

Other uses of the acronym exist in specialized domains, though they are less widely encountered. Because meanings vary by discipline, the intended interpretation of rrl should be inferred from the specific field and the surrounding explanatory text. If ambiguous, consult the source or glossary where the term appears.
