👉 Packet engineering is the process of designing, implementing, and optimizing data transmission protocols and architectures at the network layer to ensure efficient and reliable communication. It involves crafting packets—small units of data—that are encapsulated with headers containing essential information like source and destination addresses, error-checking codes, and routing instructions. By carefully structuring these packets, engineers can enhance network performance, manage congestion, prioritize critical traffic, and implement security measures. This discipline is crucial for building scalable and robust networks that can handle diverse data traffic demands while maintaining high levels of reliability and efficiency.
