Summary


The current generation of IP, version 4 (IPv4), has been
in use for almost 30 years and has supported the
Internet’s growth over the last decade .
Internet experts generally agree that IPv6 based
network would be technically superior to IPv4 based
network.

Increase IPv6 address space and its header structure :

Cost estimates are primarily based on likely
development and deployment Scenarios.

other miscellaneous
expanses.
Each organization/or user throughout the internet will
incur some cost in transition
Primarily in the form of labor and capital expenditures.
Expenditure will vary greatly across and within stake
holder groups depending on their existing infrastructure
and IPv6 related needs.

ISPs has to incur largest transition cost.

Individual users will incur the minimum cost
• Description of stakeholder groups




Infrastructure vendors,
Application vendors,
ISPs and
Internet users.
◦ Infrastructure vendors :
 manufacturers of computer networking hardware (e.g.,
routers, firewalls, and servers) and systems software
(e.g., operating system) that supply the components of
computer networks. Major companies in this category
include Microsoft, IBM, Juniper, Cisco, and Hewlett
Packard.
◦ Application vendors: include suppliers of e-
mail, file transfer protocol (FTP) and Web server
software, and database software, such as
enterprise resource planning (ERP) and product
data management (PDM) software. SAP, Oracle,
and Peoplesoft
are some of the largest
companies in this group.
◦ ISPs
are companies that provide Internet
connectivity to customers, larger companies, some
institutional users, and national and regional. e.g.,
BSNL, Tata telecommunication , AirTel, Vodafone,
Idea etc.
◦ Internet users
Corporate, institutional, and
government organizations, independent users
including
small
businesses
and
residential
households.
Affected Business Activities
Primary business activities of each stakeholder
group that will be affected
It is emphasized that all stakeholders will bear costs
associated with the transition of their own internal networks
from IPv4 to IPv6

Cost Categories
◦ Labor resources will account for the bulk of the transition costs
◦
◦
Memory and hardware : Some additional physical resources, such as
increased memory capacity for routers and other message-forwarding
hardware.
These expenses are treated as negligible in the cost analysis because it is
quite small compared to the labor resources required.
◦ Labor resources needed for the transition are linked to three general
business activities within the Internet supply chain—product development,
Internet provisioning services, and internal network operations.
◦ other cost: Additionally, several other cost categories, such as network
testing and standards and protocol development, span multiple business
activities and thus several take holder groups.


The penetration curves represent the estimated
share of infrastructure products and applications that
are IPv6 capable and the share of networks that are
IPv6 enabled at a given time.
This implies that costs will be distributed over time
as stakeholders gradually engage in transition
activities.

As networking staff are trained and the system is
reconfigured.

Lower costs associated with testing and monitoring
are then experienced after the enabling date.
The penetration curves
likely deployment/adoption rates for the four major stakeholder groups. The
infrastructure (Inf) and applications (App) vendors’ curves represent the path over
which vendor groups will offer IPv6-capable products to customers.



The penetration of IPv6 is likely to be a gradual
process and will probably never reach 100
percent of applications or users.
These four curves are the key penetration
metrics for the cost analysis because they
capture the timing of expenditures.
For vendors, R&D expenditures to integrate IPv6
into their products are the primary expenditure
category associated with the transition from IPv4
to IPv6.
