Sony built an IPv6 network to address limitations in its existing IPv4 enterprise network. Duplicate IP addresses from acquired companies caused routing conflicts that restricted productivity. Sony implemented both IPv4 and IPv6 protocols to support legacy systems while transitioning to the new standard. This provided increased flexibility, reduced costs, and enabled greater collaboration across the company through a more versatile network without communication constraints.

Introduction
Across all types and sizes of organizations, the Internet and networks have changed the way
that business is conducted. Twenty years ago, computers were glorified typewriters that could
not communicate with one another. If we wanted to communicate we used the telephone.
Today computers constantly exchange data with each other over distance and time to provide
companies with a number of significant advantages. The convergence of access technologies,
cloud, 5G networks, multitasking mobile operating systems, and collaboration platforms con-
tinues to change the nature of work, the way we do business, how machines interact, and other
things not yet imagined. In this chapter you will learn about the different types of networks,
how they affect the way that businesses communicate with customers, vendors, and other
businesses, and how the largest network, the Internet, is enabling massive automatic data col-
lection efforts from “things” rather than from people.

Sony Builds an IPv6 Network to Fortify
Competitive Edge
Sony’s Rapid Business Growth
In the early 2000s, Sony Corporation had been engaged in strate-
gic mergers and acquisitions to strengthen itself against intensifying
competition (Figure 4.1). By 2007 Sony’s enterprise network (internal
network) had become too complex and was incapable of supporting
communication, operations, and further business growth (Table 4.1).
The enterprise network was based on IPv4. A serious limitation was
that the IPv4 network could not provide real-time collaboration among
business units and group companies.
Expansion efforts were taking too long because of the compl ...
