I. Introductio
IP network capacity planning is a very important task that has received little attention in the research community. The capacity planning theory for traditional telecommunication networks is a well explored area [1], which has limited applicability in a packet-based network such as the Internet. It normally depends on the existence of a traffic matrix, identifying the amount of traffic flowing between any source to any destination of the network under investigation. Moreover, it requires accurate modeling of the incoming traffic, as well as accurate predictions of its future behavior. The above information is then combined in a network simulation to identify the points where future upgrades will be needed.
