IoT Network Architecture and Design
Module 1-partII
By: Prof. Manjula T R
, IT, OT and IoT
Drivers Behind New Network Architectures
• It is important to note that while some similarities between IT and IoT
architectures do exist, for the most part, the challenges and requiremen
of IoT systems are radically different from those of traditional IT networ
• OT networks drive core industrial business operations. They have unique
characteristics and constraints that are not easily supported by tradition
IT network architecture.
• The difference between IT and IoT networks is much like the difference
between residential architecture and stadium architecture.
• While traditional network architectures for IT have served us well for ma
years, they are not well suited to the complex requirements of IoT
• These differences and challenges are driving fundamentally new
architectures for IoT systems.
, scale
• The scale of a typical IT network is on the order of several
thousand devices—typically printers, mobile wireless devices,
laptops, servers, and so on
• But now consider what happens when the scale of a network
goes from a few thousand endpoints to a few million.
• Based on scale requirements of this order, IPv6 is the natural
foundation for the IoT network layer.
, security
• The frequency and impact of cyber attacks in recent years has increased dramatical
• Protecting corporate data from intrusion and theft is one of the main functions of t
department.
• However, despite all the efforts mustered to protect networks and data, hackers sti
ways to penetrate trusted networks.
• In IT networks, the first line of defense is often the firewall.
• It would be unthinkable to position critical IT endpoints outside the firewall.
• However, IoT endpoints are often located in wireless sensor networks are not only
the world but physically accessible
