Network Function Expansion for Image Forming Apparatuses

The patent implements dynamic function level adjustment where the network adapts its function level based on the capabilities of connected apparatuses. When a new apparatus with advanced functions joins, the network dynamically raises its function level to accommodate these new capabilities, rather than statically maintaining the lowest common denominator. This allows the system to evolve and utilize new functions while maintaining backward compatibility through appropriate function mapping and translation layers.

The system changes the function level parameter dynamically based on the capabilities of connected apparatuses. By detecting the function levels of participating devices and adjusting the network's operational function level accordingly, the system can maximize the utilization of available capabilities. This parameter change approach enables the network to operate at higher function levels when advanced apparatuses are present, thereby resolving the contradiction between maintaining compatibility and utilizing new functions.

The patent segments the network system into distinct function level layers, where each layer handles specific sets of functions. This segmentation allows new functions to be added at higher layers without fundamentally restructuring the entire system. The function expansion management unit operates as a separate modular component that coordinates between different function levels, thereby adding functionality while containing system complexity through structured organization.

The function expansion management unit acts as an intermediary between apparatuses with different function levels and the network core. This mediator translates and coordinates communications between devices with varying capabilities, managing the complexity of heterogeneous function levels. By introducing this intermediary layer, the system can support diverse functionalities without requiring every component to handle all possible functions, thus adding versatility while managing system complexity.
