Wide-area OpenFlow NetworkThrough the experience in trials (demonstration oftraffic engineering, etc.) on our wide-area OpenFlownetwork, we reached the initial design of RISE– Multi-tenancy (open access) VSI (Virtual Switch Instance)– Overlay networking Path-Port mappingApr. 1, 20154
Multi-tenancy with VSI VSI is a switch virtualization mechanism similar to VLAN– NEC’s switches support VSI A VSI is defined by a VLAN ID and a set of ports Different VSIs are independently controlled by different controllersVSIVSIVID 100Port 1, 2, 8VSIVID 200VID 300Port 3, 4, 8 port 5, 6, 7, 8VSI configurationPort #1 2 3 4 5 6 7 8 VID: 100 VID: 200VID: 300 Physical SwitchApr. 1, 20155

Issues in RISE 2.0 Limited network topology for experiments Limited number of concurrent user slicesApr. 1, 201511
Users Need More Flexibility inNetwork TopologyThe topology of RISE OpenFlow network is tightly bound tothat of JGN-X– Experimental network topology is highly limited.User(Experimenter)Apr. 1, 201512
Limited Number of User SlicesUsers often want VSIs with many links to other switches– More links mean more choices for packet forwarding control– Only 16 VSIs can be configured in a NEC’s OpenFlow switchSapporoFukuokaOkayamaSold outKanazawaSold outOsakaLos AngelesSendaiTokyo (NTT)SingaporeNagoyaNahaTokyo (KDDI)Sold outApr. 1, 2015Bangkok13

Summary We have been developing and operating theRISE testbed– We are providing SDN/OpenFlow capability to usersas well as using it in our infrastructure We are looking for opportunities for internationalcollaboration with global partners– Internet2, TransPAC3, Pragma-ENT, FIRE/OFELIA,FELIX, etc. We are much interested in SDN/OpenFlowvirtualization and multi-domain federationThank you!!Apr. 1, 201518
