Weighted Random Early Detection. RED uses an algorithm to randomly discard packets.The result of
WRED
the drop is that the source detects the dropped traffic and slows its transmission. WRED combines the
capabilities of the RED algorithm with IP precedence. This combination provides for preferential

interface starts to get congested and provide differentiated performance characteristics for different
classes of service.
