Mobility-Aware Prioritized Flow Rule Placement in Software-Defined Access Networks

Software-defined access networks (SDAN) have gained considerable attention due to the flexible and fine-granular mobile traffic management. Due to the dynamic mobility feature, an efficient flow rule management method is required in SDAN. To deal with the challenges of the mobility feature and limited rule space in forwarding nodes, a mobility-aware prioritized flow rule placement scheme in SDAN is proposed. The proposed scheme proactively performs the flow rule placement based on the flow characteristics considering delay-sensitiveness since it can directly affect users’ QoS experiences.
