The design and implementation of multilayer traffic division based on hash computing

When a website needs to evaluate the effect of its new function or new strategy, the best way is to select a little part of all traffic to do the experiment. There is a premise that we must divide the all traffic firstly. This paper puts forward a multilayer traffic division architecture and relative hash algorithms to divide the traffic uniformly and randomly. This paper firstly discusses the single layer traffic division architecture and points out its disadvantages, then puts forward a multilayer traffic division architecture and hash algorithms. This paper has done enough experiments to verify the practicability of the architecture and algorithms.
