Real-Time Monitor System in SDN via P4

In today’s interconnected world, networks play a vital role in enabling communication and data transfer between devices. Network interconnection devices refer to any hardware that connects different network resources, allowing these various devices to exchange information through different protocols and technologies. This enables the sharing and seamless flow of information among these devices, facilitating mutual connectivity and data exchange. 

Network performance monitoring involves continuously monitoring the behavior and performance of a network to identify potential issues, optimize performance, and ensure reliable communication. [1] Networks can be as small as a home network connecting a few devices or as vast as the global internet, connecting billions of devices worldwide. Understanding the function of networks and ensuring their optimal performance is crucial in modern computer science. 

Real-time monitoring systems provide administrators with instant insights into network performance. These software-based solutions capture, process, and analyze network data in real time, allowing prompt issue detection and resolution. Such systems optimize data transfer and minimize downtime, ensuring efficient network operation. 

Software-Defined Networking (SDN) is an approach to network management that enables dynamic, programmatically efficient network configuration in order to improve network performance and monitoring. [2] SDN is the decoupling of the network into distinct control (software) and data (hardware) planes.[3] 

P4 (Programming Protocol-Independent Packet Processors) is a programming language designed for network devices.[4] It allows administrators to customize packet processing and forwarding behavior, facilitating adaptation to new protocols and network performance optimization.[5]

This blog focuses on implementing a Real-Time Monitor System in SDN using the P4 language. By utilizing P4 to program the data plane of SDN switches, the system captures and processes network data in real-time, providing valuable insights into network performance. Network infrastructure impacts various aspects of our lives, and reliable, optimized networks ensure efficient internet access, seamless online services, and reliable communication.

The Real-Time Monitor System enhances network understanding and management, empowering administrators to promptly address performance issues. Its significance extends beyond computer science, as networks are vital for modern communication and information exchange. This research contributes to improving network infrastructure, benefiting individuals and society as a whole.
