A context-aware autonomic packet marking mechanism

Autonomic network is an important research field in network architectures. Since autonomic attributes such as context-aware, self-configuration, self-optimizing and self-management are introduced, autonomic network is capable of adapting to the heterogeneous and complex network environments. In this paper, context-aware and autonomic mechanisms are introduced into the DiffServ QoS framework and a novel context-aware autonomic packet marking mechanism (CAPM) is proposed. CAPM is capable of collecting various QoS related contexts, and adaptively adjusting network behavior to provide QoS guarantee according to users' QoS requirements and network conditions. Simulation results show that CAPM provides better performance than traditional packet marker, and improves user's quality of experience.
