Communication Device IPv6 Header Compression Judgment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing communication schemes, such as 6LowPAN, struggle to apply information volume reduction in middle-sized and large-sized networks due to the limitations of low-performance communication devices that cannot perform information compression processing, leading to potential traffic restrictions and service interruptions.
Innovation Solution
A communication device equipped with a module for judging whether communication control information can be compressed, allowing for the deletion or replacement of redundant information, enabling optimal traffic restriction and compression of IPv6 header information, thereby ensuring that only compressible devices perform compression, preventing service interruptions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If information compression processing is applied to reduce traffic volume in IPv6 networks, then traffic restriction is improved, but low-performance communication devices cannot perform the compression processing, leading to service interruptions
Solution Approach 1:
The patent applies local quality by making different parts of the network perform different functions based on their capabilities. High-performance devices perform compression processing while low-performance devices simply forward packets. This is achieved through the compression availability judgment function that identifies which devices can compress, allowing the network to optimize traffic reduction in capable devices without compromising service continuity in incapable devices.
2Quantity of substance
If compression processing is mandatory for all devices, then traffic volume is reduced effectively, but low-performance devices cannot handle the processing requirements, causing communication failures
Solution Approach 1:
The patent applies dynamics by making the compression processing optional and adaptive rather than static and mandatory. The compression availability judgment function dynamically determines whether compression should be performed based on the specific device's capabilities and the current communication context. This allows the system to adapt to varying device performances and network conditions, ensuring both effective compression where possible and broad device compatibility where compression is not feasible.

AI summary
A communication device used in a wireless system that includes plural communication devices and executes communication via at least one of the plural communication devices. The communication device includes: first means for judging whether communication control information can be compressed or not on the basis of a neighboring node search message among the plural communication devices and a response thereto, or the exchange of routing control information according to an ad hoc routing protocol; and second means for compressing the information volume of the communication control information by judging the contents of the communication control information and deleting or replacing redundant information or constantly fixed information if the communication control information can be compressed.
