Dynamic Packet Header Analysis for Real-Time Packet Type Expansion

The patent applies the dynamics principle by transitioning from a fixed hardware configuration to a dynamic configuration where packet header formats can be added, modified, or removed in real-time. The system allows the packet identification unit to dynamically adjust its packet header format table based on network needs, enabling expansion of packet identification capacity without changing the fundamental hardware architecture. This resolves the contradiction by making the system adaptable while maintaining structural simplicity.

The patent applies parameter changes by modifying the packet header format parameters dynamically. Instead of requiring hardware changes to identify new packet types, the system changes the software parameters (packet header formats) stored in the packet identification unit. This allows the system to adapt to new packet types by updating parameters in the format table, thereby expanding identification capacity without increasing hardware complexity.

The patent applies the copying principle by creating a virtual copy of packet header formats in software rather than using physical hardware copies. The packet identification unit stores packet header formats as data structures that can be duplicated and modified without requiring additional physical circuitry. This allows the system to handle multiple packet types through software copying of format definitions, thereby expanding identification capacity without increasing the physical circuit area.

The patent applies mechanics substitution by replacing the mechanical/hardware-based packet identification system with a software-based system. Instead of using dedicated hardware circuits for each packet type, the system uses software algorithms that process packet headers dynamically. This substitution eliminates the need for physical hardware updates when new packet types are added, thereby expanding capacity without increasing circuit area or costs.
