Bandwidth starvation is an important aspect to consider when deploying Triple Play Quality of Service (QoS) in Internet Protocol (IP) network. How to guarantee each class of QoS running smoothly with enough bandwidth when facing congested network. Trafϐic policing technique has been proposed by author to ensure voice trafϐic is separated from other class instead of using Low Latency Queuing (LLQ) of Weighted Fair Queuing (WFQ). This paper addresses the effect of trafϐic policing and Random Early Detection (RED) to quality of service in term of delay, jitter and packet loss. The result show trafϐic policing with combination using RED is promised each class of WFQ gets enough bandwidth and avoid bandwidth starvation. Simulation results show end to end delay for voice 0.02 second, voice jitter 0.00025 second,video delay 0.05 second,video jitter 0.0005. These paramaters accepted ITU-Y1541 standard. For queuingdelay paramater the result is 0.02 second.
