LPB: A Novel Load Balance Algorithm for OPSquare DCN under Real Application Traffics

Research output: Chapter in Book/Report/Conference proceedingConference contributionAcademicpeer-review

Abstract

Network virtualization in today's data center (DC) creates new heterogeneous traffic patterns different from what so far have been reported in literatures. To properly evaluate the DC network performance, a virtualized DC traffic model is developed from the real application traffics. In this paper, we propose a novel lowest path buffer (LPB) algorithm and evaluate the network performance of LPB in OPSquare DC under the developed traffic model. Compared with Round- Robin and Localflow, LPB could achieve 23.7% and 32.1% less latency, respectively. Besides, LPB provides lower packet loss with respect to Round-Robin, Drill and Localflow.
