The primary goal of this paper is to analyze bandwidth control techniques in order to propose an architecture to improve bandwidth usage. Network architecture employs several techniques in order to manage, predict and handle traffic issues due to Ethernet's best effort delivery system. Bandwidth allocation, traffic engineering and a post analysis resulting architecture are presented in that order. Ethernet's resources are dissected in order to study each component separately and present a traffic-effective architecture at each hierarchical level. The analysis reported in this paper indicate that by improving each topology hierarchical level, network performance is increased globally.
