GDED-X schemes for load balancing on heterogeneous OTIS-networks

Abstract

In this paper, several diffusion schemes, designed for load balancing on optical transpose interconnection system (OTIS), have been generalized to heterogeneous OTIS-networks,based on an ideal of divide and conquer. These generalized schemes are called GDED-X and they schedule the load flow on intragroup links and intergroup links separately. Contrasted with other existing schemes available to heterogeneous networks, GDED-X schemes have a prominent promotion in efficiency and stability of iteration. Some theoretical evidences and experimental results are also be given to show that GDED-X schemes are better than those traditional X schemes for heterogeneous OTIS-networks, which shows the usability of our proposed schemes. © Springer-Verlag Berlin Heidelberg 2007.
