And ....by end 2003 access will be :


1
B fixed IP nodes (ISP access etc)


1 B mobile nodes


1 B circuit switched and high bandwidth nodes

and combinations thereof for various convergence services


plus

x Million Bluetooth machine
-
machine communications


plus

x Million xDSL etc nodes with n>10 logical users per node


plus

x Billion Mobile Internet sessions calling on services


plus

many Million Internet hosts (2001: 120 M, IPv4 limit approx
200 M)


thus putting in focus the need to solve IP address crunch in
some regions of the world, and add new capabilities in this
connection

interoperability with IPv4 services)


128
bit addresses in terminals for global reachability and
scalability


Acceptance,user friendliness and support : IPv6 self
configuration nodesIPv6 self configuring nodes


Simplified header for routing efficiency and performance


Deeper hierarchy and policies for network architecture flexibility


Security with mandatory seemless IPSEC support of all IPv6
devices


Bandwidth and mobility : header compression , soft hand
over,and MobileIP for computing devices


Interoperability fixed/mobile


Enhanced multi

KEY ISSUES TODAY AROUND the USE of
IPv6 In COMMERCIAL COMMUNICATIONS
NETWORKS


Identifying incremental service revenue sources for
operators derived from using IPv6,sometimes
alongsid IPv4, and match them against costs


Identifying new service revenue sources for operators
derived from using IPv6


Migration plans for infrastructure and integration
services,including OSS and Network management

DECISION PROCESS MUST BE IN
ORDER ABOVE

IPv6 opens up for changes in Business models
favorable to operators and users

-

Business /traffic/infrastructure/service business models for
IPv6/IPv4 mobile traffic and services (Ericsson Hungary)

-

Business concepts and technical DNS solutions allowing for
efficient management by operators of IPv6 addresses in relation
to subscriber profiles

-

Billing solutions with bundled IP/ non
-
IP IPDR and CDR tracking
(Ericsson EHPT)

-

Collaborations with operators and new users

USE In HIGH SPEED INTERNET ACCESS
SERVICES


Technical dominant IPv6 features:

-
increased IPv6 address space

-
IPSECv6 with both data encryption and user
authentification


Incremental revenue :

-
price multiple addresses and flows managed at same
cost (e.g Japanese 180 Mbit/s ISP’s)


New revenue :

-
price enhanced security features

USE in ENTERPRISE VPN’s and ASP’s


Technical dominant IPv6 features:

-
existence of IPv6 “flow label” field

-
MobileIPv6 integration

-
IPSECv6 integration

-
IPv6 address space breaking 4096 VLAN address limitation

-
combination with 802.1p/q/r/s QoS and extended addressing features


Incremental revenue :

-
”transparent LAN” services with reduced configuration costs

-
reduced need to map VLAN ID’s at network
-
to
-
network transition points


New revenue :

-

enterprise specific tarifing characteristics encapsulated into “flow label” field

-
services from supplying enterprises with AAA servers for their VPN’s

-
premium service revenue from mobile workers which take their virtual office with them with full security

-
M
-
Business services which can only be deployed with IPv6 features from risk points of view

-
CRM and logistics services where case/object labels and tags are linked to IPv6 addresses in
applications

USE in MOBILE TERMINALS and CONSUMER
DEVICES


Technical dominant IPv6 features:

-

Incremental revenue :

-
reduced costs in customer support from much stronger auto
-
configuration at installation time (compare e.g. WAP 1.0 terminal
configuration via SMS with Mobile Internet service configuration
with IPv6)


New revenue :

-
video streaming onto mobile terminals with flow control

-
personalized services obtained by user profiles (on server or on host)
by XML tags in IPv6 packets

USE in HOME ENTERTAINMENT


Technical dominant IPv6 features:

-

-
Neighbor discovery

-
enhanced multi
-
cast support


Incremental revenue :

-
? (VoIP revenue case doubtfull for lack of differentiation of
quality+costs)


New revenue :

-
all multimedia SIP supported services

-
business models around fee based support ,provisioning or billing
made by operators for content providers , using aggregation of
services

B.t.w some Ericsson implementations/initiatives
using IPv6


AXI 820 mobile real time IPv4/IPv6 wireless router announced
@ GSM Cannes (Ericsson Radio) and fully operational


IPv4 and IPv6 enables Media Gateways (MGW) on a low cost
high performance and highly available platform (Cello)


One comprehensive server routing IPv4/IPv6 stack with large
protocol suite incl OSPF v6


MobileIPv6 protocol by Ericsson Research


IPv6 in Ericsson Juniper router products (joint venture)


Key role in 6INIT , 6WINIT, NGI project in Europe and others


IPv6/IPv4 in Ericsson Mobile Platforms AB platforms for
terminals and PDA creation

And some other initiatives at Ericsson where IP
is in focus ...


Joint venture with Volvo on Internet car (already
demonstrated)


IP in Bluetooth components and systems (Ericsson
Microelectronics, Ericsson Technology licensing
company for Bluetooth technology)


IP in building management (JV with Skånska and
others)


and more to come...

EVOLUTION

For mobile and convergence networks , no doubt about

:

-
the need for v6

-
v6 advantages

-
v6/v4 coexistence and migration need


but :

-
lack of importance in IETF and some regions of the world as
to a realistic migration driven by cost of ownership and
competitive advantages at service level

-
the absolute need for quality implementations

-
reduce fears as to migration , retraining , legacy , etc...
