Fundamentals of the Internet of Things (IoT)

What is the Internet of Things?

Introduction to IoT

• Kevin Wallace introduces himself as a double CCIE and Cisco Press author, discussing the prevalence of the term "Internet of Things" (IoT) in networking.

• The video aims to explain what IoT is, its growth potential, and its impact on networking professionals.

Understanding IoT Through Examples

• Wallace shares personal experiences with IoT devices like his Ring doorbell, which alerts him via smartphone and Apple Watch when someone approaches his front door.

• He describes how the doorbell allows for two-way communication through a built-in camera, illustrating an application of IoT technology.

• Other examples include smart lighting systems (like Hue Lights) and remote-controlled thermostats (like Nest), showcasing how standalone devices are now integrated into services.

Growth Drivers for IoT

• The integration of various appliances into connected services marks a shift from standalone functionality to service-oriented capabilities.

• A notable statistic reveals that in Q1 2016, there were more cars connected to cellular services than phones—32% of all cellular-connected devices were cars.

Factors Contributing to IoT Expansion

• High-speed internet access has become widely available, enabling more devices to connect seamlessly.

• Broadband connectivity options have replaced dial-up connections, allowing for low-latency networks suitable for numerous connected devices.

Device Connectivity Trends

• Many modern devices come equipped with Wi-Fi or cellular capabilities; for instance, a CPAP machine can upload health data directly to healthcare providers.

• Smartphones play a crucial role in controlling and monitoring these IoT devices, highlighting their importance in everyday life.

Market Predictions and Applications

• Gartner predicts around 26 billion connected devices by 2020; Forbes estimates the IoT market will reach $267 billion in sales by then.

Top Applications of IoT

• Forbes identifies predictive maintenance as a leading application where monitoring systems alert users about equipment performance issues.

Impact of IoT on Business Operations

Communication and Routing in Assembly Lines

• The integration of assembly lines allows for communication between different flows, enabling rerouting around maintenance issues. This is likened to a routing protocol that circumvents failures in network segments.

Automated Inventory Management Example

• Heineken utilizes automated inventory management by monitoring kegs delivered to bars. They track the amount and freshness of beer, ensuring timely delivery before stock runs out.

Cisco's Role in IoT Technology

• Heineken's technology for keg monitoring is powered by Cisco Jasper, an Internet of Things company acquired by Cisco. This highlights Cisco's involvement in advancing IoT applications.

Waves of IT Impacting Business

• Rowan Trollop from Cisco discusses three waves of IT impact:

• First Wave: Computing (1950s-60s), where businesses used IBM mainframes for data processing.

• Second Wave: The rise of the internet (1990s), enhancing communication with partners and customers.

• Third Wave: The Internet of Things (IoT), fundamentally changing product design and manufacturing processes.

Transformation through the Internet of Things

• Unlike previous waves that changed how tasks were performed, IoT alters what products are made. For example, thermostats now include Wi-Fi connectivity controlled via smartphones, showcasing a shift in product capabilities.

Challenges and Considerations for Networking Professionals

Security Concerns with IoT Devices

• With numerous devices connected to the internet, security becomes paramount to prevent unauthorized access or compromises, such as hacking into home security systems or vehicles.

Infrastructure Requirements for IoT Applications

• A robust infrastructure is essential to support diverse IoT applications. IPv6 addressing is crucial due to the limitations faced with IPv4 addresses; IPv6 provides ample IP addresses for devices like cars and thermostats.

Protocol Adaptations for Low Power Devices

• Not all IoT devices can support high-power components like gigabit network interface cards. Alternative protocols are necessary:

• 6LoWPAN: Allows IPv6 over low power wireless personal area networks.

• RPL: A routing protocol designed specifically for low power lossy networks (LLNs).

Compatibility with Current Technologies
