Redesigning transaction load balancing on electronic funds transfer scenarios

Abstract

The use of electronic medias for payment has been increasingly adopted, instead of employing money in currency paper or check directly. Considering this electronic funds transfer (EFT) scenario, we developed a model called GetLB which comprises not only a completely new and efficient scheduler but also a cooperative communication infrastructure for handling heterogeneous and dynamic environments. The scientific contribution consists of a scheduling heuristic that combines static data from transactions and dynamic one from processing nodes to overcome the limitations of Round-Robin. Besides the GetLB's description, this article also presents a prototype evaluation by using both traces and configurations obtained with a real EFT company.
