- Abstract
- The advanced information technology (IT) will promote the transformation of communities the world over into an information society and a knowledge-based economy in the next generation. During the past years, the explosive growth of the Internet's popularity has brought a great number of changes in the telecommunications area. The current Internet Protocol (IP)-based networks face tremendous requirements such as quality of service (QoS) guarantees, efficient traffic engineering (TE), network scalability, and high network performance, in accordance with the emergence of diverse Internet services. The main focus of this paper is on the evaluation of traffic engineering mechanism supporting QoS in an IP environment. It allows packet routing to be separated from packet forwarding, so that it provides explicit routing and traffic engineering. QoS-based signaling allows requirements of QoS guarantees and traffic engineering to be mapped onto a traffic forwarding path and traffic handling mechanisms, and permits Internet service providers (ISPs) to engineer traffic efficiently so that the utilization of network resources is enhanced and profits may be increased
