Summary of Fundamentals of the Internet of Things (IoT)

The video "Fundamentals of the Internet of Things (IoT)" by Kevin Wallace, a Cisco expert and author, provides an in-depth overview of IoT, focusing on its technological concepts, applications, growth, and implications for networking professionals.

Key Technological Concepts and Product Features:

• Definition of IoT: IoT refers to everyday devices connected to the internet, transforming standalone devices (like doorbells, thermostats, lights) into remotely controllable services.
• Examples of IoT Devices:
  • Ring doorbell with motion alerts and two-way communication.
  • Hue smart lights with remote color and power control.
  • Nest thermostat for remote temperature management.
  • CPAP machine with cellular connectivity for health data monitoring.
• Growth Drivers:
  • Availability of high-speed, low-latency broadband and cellular networks.
  • Increasing integration of Wi-Fi and cellular radios in devices.
  • Widespread use of smartphones as control and monitoring hubs.
• Market Growth:
  • Gartner predicted 26 billion connected devices by 2020.
  • Forbes projected the IoT market to reach $267 billion by 2020.
• Top IoT Applications (Forbes):
  1. Predictive Maintenance: Monitoring equipment health and alerting for maintenance needs (e.g., car tire pressure and oil life notifications).
  2. Self-Optimizing Production: Automated rerouting in manufacturing lines to avoid downtime.
  3. Automated Inventory Management: Example of Heineken’s keg monitoring system for freshness and quantity, using Cisco Jasper technology.
• Cisco’s Role:
  • Acquisition of Jasper, now Cisco Jasper, to provide IoT device and service management.
  • Cisco’s IoT and Applications Division led by Rowan Trollop.
• Historical Context of IT Waves (per Rowan Trollop):
  1. Computing wave (1950s-60s) automated tasks.
  2. Internet wave (1990s) improved communication.
  3. IoT wave changes what businesses produce by embedding connectivity into products.

Networking and Security Considerations:

• Security: Critical due to the vast number of internet-connected devices, requiring robust measures to prevent breaches (e.g., protecting home security systems or connected cars).
• Infrastructure: Need for scalable networks to support billions of devices.
• IPv6 Importance: Essential to provide enough IP addresses for IoT devices, as IPv4 address space is insufficient.
• IoT-Specific Protocols:
  • 6LoWPAN: IPv6 over low-power wireless personal area networks, suitable for small, low-power devices with limited bandwidth.
  • RPL (Routing Protocol for Low-Power and Lossy Networks): A routing protocol designed for IoT environments.
• Cisco IOS Support: Some Cisco routers support RPL in recent IOS versions, enabling IoT routing capabilities.

Summary:

The video emphasizes the reality, growth, and broad impact of IoT on business and networking careers. It highlights how IoT transforms devices into services, the importance of new protocols and addressing schemes, and the critical need for security and robust infrastructure.
