Abstract


The demand on high bandwidth internet connections and applications is growing very fast due to the variety of internet arising usage either on business or entertainment. The Internet Service Providers (ISPs) have to enhance their internal networks in terms of bandwidth utilization and resources management. Two different technologies have been provided to help in solving the bandwidth utilization issues inside the ISPs networks, the diffserv Quality of Service (diffserv - QoS) and the Multi-Protocol Label Switching – Traffic Engineering (MPLS-TE). In this paper, the two technologies are used in conjunction with each other to get the highest performance, the best resources management and the efficient bandwidth utilization.
