WRED Definition: WRED (Weighted Random Early Detection) is a queue management algorithm used in network devices to prioritize and manage traffic by selectively dropping packets before the buffer is full.
WRED (Weighted Random Early Detection) is a congestion avoidance mechanism used in network devices, particularly routers, to manage and control network congestion. It works by randomly dropping packets before the network becomes congested to prevent buffer overflow situations. WRED assigns different dropping probabilities to different types of traffic based on defined thresholds, prioritizing more important packets and providing a more efficient way to manage network congestion and maintain quality of service.
