Case Study: Implementing TCP$/$IP in a Multinational Company

Background:

A multinational company with offices in multiple countries is upgrading its IT infrastructure to

support better communication and data sharing between its offices. The company$$s IT team

decided to implement the TCP$/$IP protocol suite to manage data transmission across the

company's intranet and over the internet.

The company faces several challenges:

$1.$ Different offices use different addressing schemes.

$2.$ There are varying maximum packet sizes due to different local network configurations.

$3.$ Security is a priority, as sensitive data is shared between offices.

The company is interested in leveraging Virtual Private Networks $($VPNs$)$ and IPsec to enhance

security.

$***$ This case study highlights the implementation of TCP$/$IP protocols in a large$-$scale

multinational company, focusing on communication, security, and operational challenges.

Case Questions

$1.$ What are the key benefits of using the TCP$/$IP protocol suite for a company with

global operations?

$2.$ What is the role of routers in ensuring efficient communication between the

company$$s offices located in different countries?

$3.$ Why should the company consider using a VPN in conjunction with IPsec for secure

communication between its offices?

$4.$ Explain how the different layers of the TCP$/$IP architecture interact when a user

from the company's New York office sends a file to the office in Tokyo.

$5.$ What challenges might the company face when integrating IPsec with its existing

infrastructure, and how can they address these challenges?
