“Virtual Node (VNode) Project”Joint Research Effort since 2008– NICT, U. Tokyo (Prof. Nakao), Hitachi, NEC, Fujitsu, NTTNICT, U. Tokyo (Prof. Nakao), Hitachi, NEC, Fujitsu, NTT

Promoting Advanced Network Virtualization with innovative functionalitiesinnovative functionalities– Resource isolation among slices

Deep programmability for in network processing– Deep programmability for in‐network processing

– Dynamic slice reconfiguration

Accommodation of local physical network islands– Accommodation of local physical network islands

– Scalable experiments with CoreLab VM clusters

VNode System ConceptDesign, 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 QoSEach slice can be designed uniquely; different topology, addressing, bandwidth, QoS parameters.Application‐oriented functionalities can be implemented in node slivers running software program.software program.• A slice can use a customized protocol.

Our focuses in theme 149-a (1/2)Evolvable network virtualization architecture– Increase a variety of building blocks for VNodesy g

• 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 d f th lnodes from the resource pool.

Sli i “E d t E d”Slices spanning  End‐to‐End– Virtualization of User terminals and wireless access points to make them slice awaremake them slice‐aware.

Our focuses in theme 149-a (2/2)Easy Opt‐In– Everyone can connect to a slice easily and securely.

• Use of IKE for e ample• Use of IKE, for example.– 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 gatewaysProgrammability in Redirectors and Access gateways• Scalable resource isolation mechanism using “hierarchical shaper” in Redirector

Methodology to evaluate network virtualization systems– Methodology to evaluate network virtualization systems• Benchmarking for functionalities and performance in dynamically changing usage

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?– 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 lNV 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?
