RED is most useful in enterprise and service provider networks on output interfaces where congestion is expected to occur. Edge routers or switches typically classify and mark packets as the packets enter the network. Congestion avoidance mechanisms can use these packet markings to indicate a set of drop criteria for a traffic stream.

Congestion avoidance mechanisms are also applicable to the campus or LAN environment. In these networks, congestion avoidance is best used on interfaces that connect to WAN gateways, because these interfaces are typically sites for congestion to occur.
