Round-Robin Bloom Filters Based Load Balancing of Packet Flows

SDN gives the possibility to design new solutions for flow based load balancers, needed by the handling of quickly growing Internet data, and end user demands. A key element of this can be the Bloom filters and its probabilistic techniques to reduce information processing and networking costs. We selected a Bloom filter variant optimized for low footprint and designed and implemented a flow based load balancer solution. We identified an issue of such load balancers during their initialization phase in case of plug and play deployments. We propose a solution to alleviate this problem and evaluated its performance.
