Dynamic MTU Adjustment for Communication Apparatus
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication apparatuses set a single MTU value for all communication modes, leading to unnecessary deterioration of data transmission performance in wireless direct communication due to transmission packets being smaller than the maximum transmittable amount, resulting in inefficient data transfer.
Innovation Solution
A communication apparatus with a mode determination unit that sets the data amount for transmission based on whether the communication mode is wired or wireless direct, allowing for optimal MTU value settings in each mode to prevent performance deterioration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a single MTU value is set for all communication modes, then the transmission packet size can be standardized, but the data transmission performance deteriorates in wireless direct communication due to unnecessary packet size limitations
Solution Approach 1:
The patent applies dynamics by making the MTU value adjustable based on communication mode. The system dynamically switches between a first MTU value for wireless direct communication and a second MTU value for other communication modes, allowing the transmission packet size to adapt to the specific communication scenario rather than remaining fixed.
Solution Approach 2:
The patent changes the parameter of MTU value based on communication mode. By detecting whether the communication is in wireless direct mode or other modes, the system adjusts the MTU parameter accordingly - using a larger first MTU value for wireless direct communication and a smaller second MTU value for other modes, thereby optimizing transmission efficiency for each scenario.
2Reliability
If a smaller MTU value is used to ensure compatibility across all communication modes, then transmission reliability is maintained, but data transmission efficiency decreases in wireless direct communication
Solution Approach 1:
The system dynamically adjusts the MTU value based on the detected communication mode. When wireless direct communication is detected, it switches to the first MTU value optimized for that mode, and when other modes are detected, it uses the second MTU value, thereby maintaining reliability for each mode while optimizing efficiency.
Solution Approach 2:
The patent changes the MTU parameter according to communication mode detection results. By setting different MTU values (first MTU value for wireless direct, second MTU value for other modes), the system ensures transmission reliability is maintained for each specific mode while achieving optimal data transmission efficiency.

AI summary
An image forming apparatus 100 that can prevent an unnecessary deterioration of data transmission performance. The image forming apparatus 100 has a MTU value input screen 600 including options representing different MTU values each of which can be selected. When it is determined that a present communication mode is a second communication mode realized without directly connecting the image forming apparatus 100 and the external apparatus, the selected MTU value is set as an acceptable amount of the data to be transmitted in a communication between the image forming apparatus 100 and the external apparatus. When it is determined that the present communication mode is a first communication mode realized by directly connecting the image forming apparatus 100 and the external apparatus, a maximum transmittable amount of the data in the first communication mode is set as the acceptable amount of the data to be transmitted.
