The problem of providing quality of service (QoS) in the Internet stems from the original choice of a datagram packet switching service model for the Internet protocol (IP). Since, in principle, each packet can take any path to the destination, it is impossible to provide any absolute guarantees about service. This paper presents a scheme using traffic engineering techniques and implements policy based routing supported by border gateway protocol (BGP) to achieve QoS parameters (loss, delay and jitter) values within the bound for high priority voice traffic in the Internet. Simulation using OPNET shows how such techniques can achieve the desired results.
