A diffServ management scheme considering the buffer traffic rate in ubiquitous convergence network

초록

Ubiquitous convergence network consists of access networks to provide heterogeneous network services for mobile users. In this paper, we propose a hierarchical policy-based architecture model and the policy procedures based on access networks connected with Ubiquitous convergence networks. We also present a dynamic traffic management scheme which uses DifFServ mechanism and SLA for the management of end-to-end QoS in access networks. At the end of this paper, we will analyze the performance of the proposed schemes through computer simulation. © Springer-Verlag Berlin Heidelberg 2007.
