End-to-end relative Differentiated Services for IP networks
説明
In the last decade two major solutions, namely IntServ and DiffServ have been introduced to empower IP networks with quality of service (QoS) capabilities. Among these two the DiffServ, which exhibits a better scalability and is the starting point for this paper is based on a per hop shaping of the traffic. The nodes control independently the flows without knowledge about the network state or/and the limitations suffered by the flows at other hops. Thus, violation of service differentiation can also occur. To correct this inefficiency a network-wide proportional service model is proposed. After presenting the theoretical argumentation and the architecture, we also provide an algorithm that computes the shaping factor needed to sustain our architecture. We use simulation experiments to validate our proposal.
