In [[computer network]]s, '''rate limiting''' is used to control the rate of requests sent or received by a [[network interface controller]]. It can be used to prevent [[denial-of-service attack|DoS attacks]]<ref name="cisco"/> and limit [[web scraping]].<ref>{{cite magazine |last1=Greenberg |first1=Andy |title=An Absurdly Basic Bug Let Anyone Grab All of Parler's Data |url=https://www.wired.com/story/parler-hack-data-public-posts-images-video/ |access-date=12 January 2021 |magazine=Wired |date=12 January 2021 |language=en-us |url-access=limited |url-status=live |archive-url=https://web.archive.org/web/20210112164535/https://www.wired.com/story/parler-hack-data-public-posts-images-video/ |archive-date=12 January 2021 }}</ref>

Rate limiting should be used along with [[Bandwidth throttling|throttling pattern]] to minimize the number of throttling errors.<ref>{{Cite book |title=Cloud Native Using Containers, Functions, and Data to Build Next-Generation Applications |publisher=O'Reilly Media |year=2019 |isbn=9781492053798}}</ref>
