Dual Stack Module Power Control via Dynamic IP Activation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Dual stack module devices for processing both IPv4 and IPv6 data face high power consumption and resource usage, particularly in limited resource devices like M2M equipment and embedded systems, due to the need to activate both stacks even in incommunicable status or single mode operations.
Innovation Solution
A dual stack module controlling apparatus that determines the IP address version based on current assignment information and activates only the necessary TCP/UDP stack processor, IP stack processor, and IP packet preprocessor modules for the determined version, deactivating those for the other version to reduce power consumption and resource usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If both IPv4 and IPv6 stacks are activated in dual mode, then the device can process both IPv4 and IPv6 data, but power consumption and resource usage increase significantly
Solution Approach 1:
The patent implements dynamic stack activation where the dual stack module can switch between activating IPv4 stack, IPv6 stack, both, or neither based on real-time communication status and mode settings. This dynamic control allows the system to adapt power consumption to actual needs rather than maintaining both stacks continuously active
Solution Approach 2:
The system changes the operational state parameter of the stack modules (active/inactive) based on detected conditions such as communication status and mode selections. By changing these parameters dynamically, the system optimizes power consumption while maintaining necessary functionality
2Reliability
If both IPv4 and IPv6 stacks remain active in incommunicable status, then the device maintains readiness for both protocols, but resources are wasted and power consumption increases
Solution Approach 1:
The dual stack module incorporates feedback mechanisms that monitor communication status and mode settings, then use this information to control stack activation. The system continuously checks whether communication is possible and adjusts stack activation accordingly, preventing energy waste while maintaining reliability when needed
3Adaptability or versatility
If the dual stack module supports both dual mode and single mode, then it provides operational flexibility, but complex control mechanisms are required to manage stack activation appropriately
Solution Approach 1:
The control mechanism is segmented into distinct functional blocks: mode setting means for selecting operational modes, communication status detecting means for monitoring communication conditions, and stack activating means for controlling individual stacks. This segmentation simplifies the overall control logic by breaking it into manageable, independent components

AI summary
A dual stack module controlling apparatus for low power consumption is disclosed. The dual stack module controlling apparatus for low power consumption includes an IP address version determining part to determine an IP address version based on current IP address assignment information transmitted thereto from an IP address control module, and an internet protocol stack controlling part to activate a TCP/UDP stack processor module, an IP stack processor module and an IP packet preprocessor module for processing data of the determined IP address version and to deactivate a TCP/UDP stack processor module, an IP stack processor module and an IP packet preprocessor module for processing data of a different IP address version from the determining IP address version. According to the dual stack module controlling apparatus for low power consumption, one of the IPv4 and IPv6 modules may be activated as necessary.
