Cooperated traffic shaping technique for efficient accommodation of microbursts in IoT backhaul network

An aggregating switch (SW) network offers cost-effective accommodation to IoT (Internet of Things) traffic by aggregating the traffic. For more efficient accommodation, the microburst traffic must be mitigated, which occurs when massive IoT devices transmit data simultaneously. In this paper, we propose cooperated traffic shaping by SWs with estimation of the input rate from the IoT devices to increase the accommodated data size of microburst traffic and derive equations for optimal configurations. Experimental results show that the data size can be increased by 60%.
