Load Balancing Algorithm Based on Predictive Packet Loss Rate

We proposed a new load balancing mechanism, called PPLR (predictive packet loss rate), by which flow can be divided into packets and each of the packets be transferred on an individual basis to the destination through multipath. Load balancing is needed in many fields; however, current approaches have problems such as lacking of preparing for sudden spikes. In this paper, we describe how PPLR dynamically predicts loss levels over all available network paths and adjust the allocation proportion of packets for next prediction period. We present our simulation work using NS-2 and discuss performance comparison between PPLR and other load balancing mechanisms. The results show significantly better performance than ECMP.
