Abstract

The Next Generation Network (NGN) is expected to become the most important infrastructure for various services used for e-Business such as telephone services, Internet services and new generation broadcasting services. It is supposed to be integrated into all IP network. To satisfy various Quality of Service (QoS) requirements of these services not only for each service but also for every user, we have developed a hierarchical shaper. The shaper has been implemented in a QoS aware gigabit router environment. Although this shaper has to be evaluated to manage actual traffic, the influence of various network conditions on bandwidth control has not been studied thoroughly. This paper reports some experimental results and clarifies the characteristics of the shaper.
