NetFlow-Based Approach to Compare the Load Balancing Algorithms


Chin-Yu Yang, Jian-Bo Chen


Vol. 8  No. 10  pp. 276-281


The load balancing architecture is the most popular method to improve the performance of the server. The selection of the load balancing algorithms is one of the most important issues. In this paper, we use NetFlow to collect traffic for six load balancing algorithms, including least connections, round robin, minimum misses, hash, response time, and bandwidth. We compared their flow counts and packet counts separately. Both the WAN link load balancing and server load balancing are implemented. In addition, we also collected the burst traffic for server load balancing. The results for the performance of the algorithms are analyzed and compared.
