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.
