What does WIDE do?

  • Realize the future Mobile Internet
  • Find all specification problems by

implementing the spec

  • Provide free protocol stacks
  • Operate the service with the new

protocol to find any operational problems and get experience

  • Demonstrate how can the technologies

be applied

LIES: the Inter Layer Information Exchange System

  • L3 handover mechanism can be enhanced

by utilizing L2 handover information

  • A standard API to interact between L2 and

L3 is necessary

  • A draft proposal is submitted to the IRTF

as draft-irtf-mobopts-l2-abstractions

slide-14
SLIDE 14

LIES Demonstration

IPv6 Subnet 1 2 3 4 5 6 7 8 200m

  • Application: DVTS
  • Half rate: 15Mbps
  • from MN on a car to a

fixed PC

  • L3 Mobility: LIN6
  • L2: IEEE802.11a (54Mbps)
  • 8 IPv6 subnets
  • 8 access routers
  • Disruption time 3~4ms
  • L2: 1~2ms (constant)
  • L3: 1~2ms (depends on

the RTT)

slide-15
SLIDE 15

Operational Experience

  • Using IPv6 mobility technology in a real

environment is important

  • Find any potential problems
  • Prove scalability of the protocols
  • Acquire operational experience
  • Two operational activities
  • Mobile IPv6/NEMO BS public home agent
  • peration service
  • Mobile router operation with a large

number of people

slide-16
SLIDE 16

Home Agent Service

  • Operate L3 mobility

service as a Mobile Service Provider (MSP)

  • Design goals
  • Easy to use Web-

based service interface

  • Supporting both IPv4/

IPv6 access networks

  • Support full security

defined in the specs

  • Distribute the system

as an operation kit

Web Interface

  • Currently only Mobile IPv6 is

supported

  • Available functions
  • Mobile node registration
  • Home address assignment
  • Security parameters setup
  • Live CD creation
  • Next version is under preparation
  • Supports NEMO BS
  • Publicly available
slide-18
SLIDE 18

Live CD for Technology Advertisement

  • Can be burned from the

Web interface

  • Kernel and necessary

mobility programs are integrated

  • All initial configuration

has already done

  • Not so useful, however

the easiest way to try mobility functions

slide-19
SLIDE 19

Fault Tolerant Network using NEMO BS

  • Put a mobile router at

the network boundary

  • Subscribe multiple ISPs
  • When one of the ISPs

fails, the mobile router “moves” to another ISP

  • Local fixed nodes are

unaware of the movement

WIDE Camp as a Practical Network

  • What’s WIDE Camp?
  • A 4-day meeting where the WIDE

members get together one place and discusses various kinds of Internet topics

  • A temporarily network is prepared for

both infrastructure and experimental purposes

  • 200~250 people participate

Conclusion

  • Mobility technologies are getting mature
  • IETF standard protocols are available
  • High performance wireless communication
  • Implementing and operating the technology is

important as well as designing protocols

  • It is a lot of fun :-)
  • We have to prepare the coming Mobile

Internet
