Agenda

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 :◦ will enable to develop new application, ◦ Will be more secure, ◦ have ease of mobility and renumbering, ◦ end to end connectivity ◦ Efficient and will provide other benefits

Cost estimates are primarily based on likely development and deployment Scenarios.

Introduction

H/w, software, services and 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

Introduction

• 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.

Methodology

◦ 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.

Stakeholders

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.

Description Of Cost Categories And Estimation Approach

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.

Quantitative Estimation Approach

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.

Internet users incur approximately 90 percent of IPv6 transition costs. Vendors and ISPs account for the remaining costs.

Overview of relative IPv6 cost

The type of internet use or type of service being offered by each organization

The transition mechanism that the organization intends to implement( e.g tunneling. Dual-stack, translation, or a combination).

The organization-specific infrastructure comprised of servers, routers, firewalls, billing stems and standard and customize network etc.

The level of security required during the transition.

Timing of transition.
