👉 Packet fluid refers to the dynamic and adaptive nature of data packets as they traverse a network, adjusting their size, format, and routing in real-time to optimize transmission efficiency and reliability. This fluidity is crucial for adapting to varying network conditions, such as congestion or link failures, ensuring that data packets can be delivered effectively despite the changing environment. Packet fluidity is a key feature of modern networking protocols, enabling robust and efficient communication across diverse and complex network topologies.
