Kopaonik, March 6th,2005
IPv6 technology @ a glance

Unlimited Addresses



Easy way of end-system configuration – “Plug & Play”




Multiple IPv6 addresses per interface, associated with multiple networks
Security


IP address auto-configuration, enhanced DHCP (NTP, SMPT, SIP in addition GW, DNS),
DHCP prefix delegation, a.k.a. assign multiple addresses to a client.
Better support of mobility


Each IPv6 Address has 128 bits,
End-to-end connectivity, e.g. allow a routable addresses for “everything” such
as IP phones, 3G devices, sensors, personal devices, appliances
Mandatory IPSec support … but might open unknown network security hazards (new
technology!)
Multicasting: SSM, Embedded Rendezvous Points selected at session initiation,
QoS Flow Label in header allows easy packet differentiation
Multi-homing potential
IPv6 technology: Different Perspective

From the perspective of the User




Interested in services and (new) application.
Desires access to available information.
Seek for better level of interconnectivity to available
infrastructure, e.g. the “network”.
The User IS NOT interested in the IPv6 technology!
From the perspective of the Service Provider



Seeks to increase its revenue.
Continuously assess the “maturity” of the any new technology.
Considers the cost of design, deployment and maintenance of a
service as important parameters that has to be taken into
consideration prior providing a new service.
The Service Provider IS interested in IPv6 technology and the
commercial opportunities it creates.
IPv6 technology: Different Perspective

From the perspective of Government and Legislations




IPv6 priorities for Action in Europe,
Multiple IPv6-related projects (e.g. 6NET, Euro6IX), forums
eJapan
Increase competition – Improve quality of life
From the perspective of Standardisation bodies & Vendors



All “fundamental” standards are now available! Ongoing
standardisation will never end…
IPv6 is already available in many commercial products, operating
systems, (new) consumer electronics, etc.
IPv6 features are included in “standard” setups.
Most of the work is already done!
Prerequisites for adopting IPv6 technology

Asses the requirements of End-Users


Technology maturity





Availability of standards, deployments in
production environments, high availability
of new services
Support from operating systems, network
equipment, (personal) devices
(IPv4/6 unaware) Applications
Education – Training – Experience


Diverse groups of End-Users
May become the more significant
obstacle for may organisations
Proper design of new services
Short- and middle- term investments
Incentives – Services –
Conditions
Searching for new End-Users

Today Internet Users … (~10-20% of population)
 … spent as much time on the Internet as they do while watching TV!




… are interested in “ordinary” services, such as electronic mail, WWW,
p2p file sharing, chatting, etc.
… are familiar with Internet technology, at least the younger
… increase their bandwidth needs and wish to pay less money per
bandwidth unit!
Potential new Users …




… seeks to gain access to Internet or what ever it is!
… are not familiar with the networking technology and they are not
interested in getting training, e.g. elderly people.
… wants secure and easy-to use applications, e.g. “could I use only a
remote control to establish a videoconference?”
… are willing to pay more then today Internet Users (!) in order to get
access to some of the available applications.
Potential new Users surpass in numbers the today Internet Users!
Traditional interconnection services

Revenues from (analog) telephony and leased capacity
services are gradually reduced.


The deployment of “always-on” services requires the adoption
of new models for address management.


NAT solutions have increased maintenance costs
Service Providers offer new added-value services «closer» to
End Users.


New business models are needed!
Security, content management, VoIP, etc.
IPv6 (production) interconnection services are already
available


Research networks in Europe, also in South East Europe
Commercial services already available.
VoIP / VoD Applications

Peer-to-Peer VoIP

Examples



IP Telephony Services



Skype! Millions of downloads, Millions of “always-on”
subscribers.
Free-bit …
Commercial services are already available in many
countries.
Of-the-shelf equipment: VoIP routers, WiFi + Cellular
phones, etc.
TV broadcasting

Well suited to IPv6 multicast features, e.g. MLD
Broadband Home

Interconnection of home appliances



Take advantage of «plug and play» features
Reduction of maintenance cost, e.g. avoid NAT/PAT, STUN, etc.
Applications / Services







Internet connectivity
IP telephony
Streaming audio/Video, iTV
Video Multicasting / VoD
P2P Gaming – Digital audio
Remote control home appliances
Security
Mobility

Challenges





Interconnection of huge number of End
Users
Hand-off of mobile nodes (MN) through
heterogeneous networks without any
connectivity loss.
Multimedia applications
Reduction of battery consumption.
Ubiquity Network

3G Networks




Wireless Networks

WiFi, WiMax, ...

Hotspots continuously under deployment
in many countries
High interconnection speeds


True mobility
“Middle rate” interconnection speed
IPv6 support is a functional requirement
for IMS
Mobile networks, e.g. passengers of a train
Ad hoc networks

Requirements for «closed» logical networks


A node with network interconnection does not necessarily
mean the there is access from anywhere from the internet.
Different groups, e.g. customers / suppliers, social groups,
would like to create “closed” logical networks.


Take advantage of built-in Ipv6 features, such as
«autoconfiguration» and security.
Peer-to-peer applications, file sharing, etc – Distributed
architectures.
Telemetry – Monitoring Services



Monitor patients or elderly
people at their home
Environmental monitoring Sensors
Fleet management


taxis, busses, IP cars
Military applications

“One address per soldier”
Grids

Management of resources, nodes, sensors, etc




Grid middleware under development
P2P communication between resources
Requirement for large amount of IP addresses
Undergoing research projects

EGEE, 6GRID
Other Services …

RF IDs



food industry, etc
Power line communications
“Unexpected” services


How remembers how “SMS”, “ring tones”, “post-it” started
Another fancy example

Church Service by Telephone
(http://earlyradiohistory.us/1902chur.htm)
Unexpected services will arise when new End Users groups
are taking advantage of the network, demand growths,
technology matures.
Methodology for the
introduction of IPv6 Services
Steps


Analyse the advantages for the transition to IPv6.
Identify the investment cost for the deployment of a new service.


Hardware & Software, training, design, transition to IPv6, deployment, maintenance,
user support, etc.
Identify

Reduction of costs




New revenues – Increase of profits
Better quality for services
Obstacles – Reduce risk factors






Long term planning,
Alternative solutions / technologies
Increase company “flexibility”,


Reduction of cost if you migrate to IPv6, increase of cost if you stick to IPv4
e.g. new opportunities, reduction of time for deployment new services, etc.
Try to explain how the commercial risk may be overcome.
Make other to identify how IPv6 technology provides added-value to an
organisation or a company.
Face any «emotional» doubts
Explain why IPv6 technology could increase novelty – Describe how this “new”
novelty fits at the strategic objectives of an organisation or a company.
IPv6 Return of Investment (ROI)
Summary





IPv6 changes Internet
Ipv6 change the way we do business
Standards are already available
Vendors are ready!
New application will arise soon!
