References to relevant research papers are provided. The presentation aims to give an understanding of how large corporations manage their networking activities.

A Presentation on Intel
Network Infrastructure

Objectives
 The aim of this presentation is to identify a large corporation in the
computing industry and investigate their networking activities.
 This includes getting an idea of the global reach of the network.
 The investigation also requires to know the method by which such network
communications are being conducted.
 The logical design is to explain how the connection is provided to the end
devices.
 The subnet classification must show how the company performs the IP
Address Allocation.
 Then the different networking technologies and protocols should be noted.
 The presentation must also offer the best practices for safe networking.

Business Description
 The company that has been
chosen is Intel Corporation
(Lieder et al., 2019).
 It is a US based multinational
semiconductor manufacturing
company.
 It ranks as one of the top 50
among the Fortune 500
companies as per revenue
generation.
 It currently employs over
110,200 employees.

Network Communications
 A company like Intel needs to have a network capable of supporting
communications from remote sites.
 The large internal network requires use of advanced networking features
like SDN and NFV for better management (Tootoonchian et al., 2019).
 Software Defined Networking (SDN) helps separate the control plane
and data plane (Shang et al., 2017).
 Effective management of data centres, server farms and offices enable
optimal use of storage and computing resources for streaming services.

Global Network Coverage
 The internal network of Intel is
spread over the major
continents of the world.
 In each continent the network of
Intel forms an interconnect of
routers of nearby countries.
 These interconnects transmit
network connections with one
another and provide the services
to specific routers.

Satellite Communication
 The interconnects of different
continents need to communicate
over long distances.
 This is made possible with the
help of Satellites and Dishes.
 Network interconnect of each
continent have their own dish
installed.

Logical Network Design
 The logical design shows how the
network is acquired by the
interconnect.
 Then the network traffic is
transmitted to specific office routers.
 This is done using the national
broadband network infrastructure.
 Multilayer switch is used to distribute
the network to specific departments
through multiple VLANs.
 Access layer switches are used to
directly connect the devices using
the specific VLAN.

The IP table provides the subnet
configuration for 5 of the 14
countries where Intel operates.
This IP table includes the subnet
names, IP requirements, allocated
space, network and broadcast
addresses, network masks and
range of assignable IPs.
Details regarding the above are
provided for offices of each of the
five countries that were
investigated.
The major network chosen for the
subnet classification is
121.160.0.0/14.

Networking Techniques
 To make different network partitions for
different departments, server farms,
data centres and WLAN network, virtual
Local Area Network (VLAN) is used.
 These VLANs help further secure the
network by specifying rules and
permissions through ACL commands in
the router.
 IP addresses are automatically allocated
to smart devices over WLAN and to the
end devices and generic servers
through DHCP.
 Exception to DHCP are Web Server, DNS
Server and FTP Server.

Best Networking Practices
 To ensure secure networking services, the following networking practices
are recommended:
 Use of advanced security features provided by the network routers and
switches.
 Comprehensive enterprise class security suites must be installed in
every system.
 Sensitive data must be prohibited from being stored locally in client
systems.
 Use of strong passwords must be recommended to all users.

Conclusion
 The presentation identifies the objectives to investigate the networking
activities of large corporations.
 A large corporation with specific requirements is identified and
descriptions are provided.
 The network designs are provided and discussed.
 The subnet classification is given through the IP table and is discussed.
 The different networking technologies that get used are discussed.
 Best networking practices for safe networking are given.
