Network Virtualization Research In Japan

Recent Updates

NV Symposium 2011 Tokyo

Aki Nakao University of Tokyo

2011/9/10 1

Advanced Network Virtualization ! "“Network” is a communication infrastructure including link resources as well as processing and storage resources (routers)

! "Network Virtualization is not just virtualizing connectivity (VPN, logical routers), but virtualizing the infrastructure “as a whole”

! "Our objective is to run multiple different programmable networks concurrently in an isolated manner.

What’s the most viable application of NV that can convince your grandma NV is a good idea?

Benefit of Network Virtualization

Network Slicing for Public Safety and for Emergency

4

Allocating Resources for Emergency ! "Dilemma of “Inflexible” Infrastructure

If resources reserved and nothing happens, wasted.

If resources not reserved and anything happens, troublesome.

5

We need a slice of resources to be allocated on demand! And protocols do not have to be a standard one!

Flexibly Programmable NV Infracture Op-A and Op-B run as a service

Wired Emergency Slice

The current Internet Op-A and Op-B services interleaved

Instantly and Dynamically Allocate an Emergency Slice

WiVi [wiːviː] Wi-Fi Network Virtualization Infrastructure

What does “Wi-Fi AP virtualization” mean?

WiVi attacks these challenges… ! "OS & Wireless Device Virtualization

! " Realizing an illusion of multiple virtual wireless devices for a given physical wireless device

! "Security Isolation ! " Grant a slice exclusive control of virtual wireless devices

! "Performance Isolation ! " Isolate bandwidth per virtual wireless device

! "Elasticity ! " On-Demand (de)allocation of slices

! "Programmability ! " Facilitate development of innovative AP functionality
