Some　innovation　network　architectures,　such　as　Software　Defined　Network　(SDN)　and　Information-Centric　Networking　(ICN)　attract　more　and　more　interest　in　recently　years.　Network　virtualization　and　reconfigurable　are　the　basis　of　these　new　network　technologies.　Besides　theoretical　study,　a　large　amount　of　research　works　should　be　done　to　test　and　verify　the　assumptions　on　the　testbeds.　Some　large-scale　research　network　test　platforms　are　designed.　But　they　are　not　suitable　for　researchers　to　carry　out　small-scale　network　virtualization　experiment,　because　they　are　quite　complexity　or　still　at　primary　stages.　However,　the　software　platforms　are　unable　to　simulate　the　real　network　traffic　and　test　the　efficiency　of　application　software.　Therefore,　it　would　be　a　better　choice　to　design　a　small-scale　virtualization　testbed　that　cost　less　and　can　be　easily　deployed.　In　this　study,　we　design　a　small-scale　reconfigurable　network　emulation　testbed　called　RNET,　based　on　Click　Modular　Router,　especially　for　the　new　network　paradigms　research　work.　Through　a　lot　of　independent　experiments　which　using　multiple　protocols　and　different　kinds　of　applications,　we　conclude　that　RNET　would　be　an　efficient　testbed　for　future　network　researches.　©　2013　Asian　Network　for　Scientific　Information.
