Abstract
Data packets are received by the REDP traffic conditioning marker from the upstream domain and each have a red, yellow, or green priority level. The traffic conditioning marker monitors the rate of green data packets flowing through the A random early demotion and promotion (REDP) traffic conditioning marker is located between an upstream domain and a downstream domain. If the rate exceeds a negotiated rate, the traffic conditioner randomly and fairly demotes green packets to yellow. If the rate is less than the negotiated rate, the traffic conditioner randomly and fairly promotes yellow packets to green. The traffic conditioner removes the phase effects that occur in conventional markers.
