LoRa is a long range wireless radio technology for low power wide area networks (LPWANs) used in IoT and M2M applications. It uses license-free sub-GHz frequency bands and spreads signals over a wide bandwidth for long-range transmissions of up to 5-15 km in rural areas and 2-5 km in urban areas using low power consumption from battery-powered devices. The LoRa Alliance oversees the LoRaWAN standard to enable interoperability.
The document provides an overview of SDN and related technologies demonstrated in a Dell lab, including:
1. SDN allows separation of the control plane and data plane in networking devices using an abstraction layer and OpenFlow protocol for communication between controllers and switches.
2. The lab topology included VLT and MLAG for redundancy between switches, as well as a Big Monitoring Fabric using Dell switches and a controller to provide network packet brokering without dedicated devices.
3. Configuration snippets were provided for the Dell switches used in the VLT topology, including the S4810 VLT peers and the S4820T server access switch with port mirroring.
The Zen of Python values simplicity, readability, and providing a clear obvious way to accomplish tasks over complexity. It emphasizes that errors should not pass silently, implementations should be easy to explain, and namespaces are useful for organizing code.
