Elastic and strict load balancing via consistent hashing

Abstract (in Japanese) (See Japanese page) 
(in English) Load balancing is a key function constructing massively distributed systems. Stateful services like SIP and distributed hash tables need special load balancing units that route the related packets, which refer to the same states or data, to a certain server. Many works proposed the load balancing schemes with consistent hashing. But consistent hashing has a defect that it raises load unbalance, sometimes large. The unbalance is caused by its determination of distribution logic, which allocates the hash-space at random. Hence we propose a method of allocation that realizes strict load balancing, considering fault-tolerance and elastics (variation of the number of servers). In addition to that, we evaluate the effectiveness of our method by simulation.
