IoT-based smart city workflows require energy-efficient network infrastructure but due to the resulting resource constraints are typically unable to handle traffic spikes. Using two Alcatel Lucent OmniSwitch 6465-P12 devices that cooperate, we show how offloading leads to better handling of traffic and associated intelligence computation. One OS6465 serves as a central smart network switch, managing communication and data flow between IoT devices and the other switch. The implementation and integration of three smart city workflow scenarios were tested in a lab environment, focusing on IP camera monitoring for traffic surveillance, environmental monitoring and room occupancy detection. The chapter details the setup, including dynamic QoS policies to manage video streaming effectively and ensure high-quality performance. Moreover, it discusses benchmarks performed on the switches, including packet counters, port monitoring, and the use of the cron-app for scheduled tasks. These experiments demonstrate the system's performance, efficiency, and capability to adapt to evolving smart city requirements while maintaining optimal resource utilization.
