TDLS, shortened from Tunneled Direct Link Setup, is "a seamless way to stream media and other data faster between devices already on the same Wi-Fi network." Devices using it communicate directly with one another, without involving the wireless network's router.[http://www.androidpolice.com/2013/10/31/kitkat-feature-spotlight-wi-fi-tdls-support-allows-for-faster-direct-data-transfer-on-a-wi-fi-network-without-slowing-other-devices/ KitKat Feature Spotlight: Wi-Fi TDLS Support Allows For Faster Direct Data Transfer On A Wi-Fi Network Without Slowing Other Devices], androidpolice.com

Wi-Fi Alliance added certification for TDLS in 2012. It describes this feature as technology that enables devices to link directly to one another when connected to a traditional Wi-Fi network. Wi-Fi CERTIFIED TDLS devices can set up secure links and transfer data directly between them. TDLS-linked devices benefit from an optimized connection to do things such as streaming video or synching content, without burdening the network as a whole.[https://www.wi-fi.org/news-events/newsroom/wi-fi-alliance-now-certifying-tunneled-direct-link-setup Wi-Fi Alliance® now certifying Tunneled Direct Link Setup], Wi-Fi Alliance
