2 Virtual Node (VNode) Project Joint Research Effort since 2008 NICT, U. Tokyo (Prof. Nakao),Hitachi, NEC, Fujitsu, NTT Promoting Advanced Network Virtualization with innovative functionalities Resource isolation among slices Deep programmabilityfor in network network processing Dynamic slice reconfiguration Accommodation of local physical network islands Scalable experiments with CoreLab VM clusters

3 Hybrid View ANUE ANUE ANUE VNode System Concept Design, construct, modify, and destroy your own virtual networks (a.k.a. Slices) Single NW virtualization platform accommodates multiple isolated slices. Each slice can be designed uniquely; different topology, addressing, bandwidth, QoS parameters. Application oriented functionalities can be implemented in node slivers running software program. A slice can use a customized protocol.

5 VNodes Depolyment on JGN-X 4 VNodes and 7 AGWs with the Management system already. More Nodes will be added in coming fall. Ready for various experiments.

6 Next Step About to start a new 4 years project R&D for Network Virtualization Substrate Technologies to support New Generation Nt Networks, k Theme 149 a ( ア ), funded dby NICT NTT, U. Tokyo, Hitachi, NEC, Fujitsu Close relation with Application Service Platform/Middleware for Net Virt, 149 i ( イ ) Eight Applications for New Generation Networks, 149 u ( ウ ) NwGN application 1 (149 u) slice NwGN application 8 (149 u) slice Application Service Platform (149 i) VNodes Management System Access Gateways Wireless Access point Virtulization Net. Virt. Substrate Theme 149 a Network Infrastracture User Network accommodation Cloud

7 Our focuses in theme 149-a (1/2) Evolvable network virtualization architecture Increase a variety of building blocks for VNodes Enable alternative node realization such as OpenFlow Redirectors Coordinataion / integration with L2 and optical switch substrates Resource abstraction to integrate new blocks that come out in future. Toy block networking easily combine most appropriate nodes from the resource pool. Slices spanning End to End E d Virtualization of User terminals and wireless access points to make them slice aware.

8 Our focuses in theme 149-a (2/2) Easy Opt In Everyone can connect to a slice easily and securely. Use of IKE, for example. eample Everyone can easily make a slice Cooperation with theme 149 i Good Balance between functionalities and performance Enhancement of VNodes Increase performance of Programmer Programmability in Redirectors and Access gateways Scalable resource isolation mechanism using hierarchical shaper in Redirector Methodology to evaluate network virtualization systems Benchmarking for functionalities and performance in dynamically changing usage

10 Questions for other panelars and audience Do NV realize more efficient network? More functionality, but what sacrifice? Granularity, or size of slices What kind of slices do you want? (Big?) Slices per protocol (IPv6 slice, ) (Small?) Slices per user/application group How many slices, and how they different? NV d t l NV and new protocols It is said that one objective of NV is to be a cradle of new protocols. Do you have some protocol to try? When they come? What kind of protocols? They will come through a lot of application trials, eventually?
