Solution Overview
Problem
Existing methods for controlling the number of simultaneous couplings to a server in information processing systems are static and fail to adapt to changing environments, leading to suboptimal quality of service due to unpredictable load variations and device configuration changes.
Innovation Solution
A dynamic method that records and compares statistics of request forwarding time and processing time to adjust the upper limit of simultaneous couplings, ensuring optimal load balancing and minimizing response time by dynamically changing the number of allowed couplings based on real-time conditions.

Engineering Contradiction Analysis
1Quantity of substance
If the maximum number of simultaneous couplings is increased to handle more requests, then the server's capacity to serve clients is improved, but the response time deteriorates due to excessive load
Solution Approach 1:
The patent implements dynamic adjustment of the maximum number of simultaneous couplings based on real-time server load conditions. The control device monitors the server's processing capacity and response time, and automatically modifies the coupling limit to optimize performance. This transforms the static coupling limit into a dynamic parameter that adapts to changing system conditions, resolving the contradiction between handling more requests and maintaining response time.
Solution Approach 2:
The system establishes a feedback mechanism where the control device continuously monitors server performance metrics (response time, load status) and uses this information to adjust the maximum number of simultaneous couplings. When response time exceeds thresholds or load becomes excessive, the system reduces the coupling limit; when performance is good, it increases the limit. This closed-loop control resolves the contradiction by using feedback to balance request volume and response quality.
2Productivity
If the maximum number of simultaneous couplings is set high to improve service capacity, then more clients can be served, but the quality of service deteriorates under varying loads
Solution Approach 1:
The patent makes the coupling limit dynamic rather than fixed, allowing the system to adapt to varying loads while maintaining service quality. The control device adjusts the coupling limit in real-time based on server conditions, ensuring high productivity when capacity is available and maintaining reliability when load increases, thus resolving the contradiction between service capacity and quality of service under varying conditions.
Solution Approach 2:
The system changes the parameter of maximum simultaneous couplings based on server load conditions and performance metrics. By modifying this parameter dynamically according to actual system state, the system achieves both high productivity during low-load periods and maintains reliability during high-load periods, resolving the contradiction between service capacity and quality of service.
3Ease of operation
If a static upper limit of simultaneous couplings is set in advance, then the system is simple to operate, but it cannot adapt to changing environments and load variations
Solution Approach 1:
The control device automatically monitors server load and adjusts the maximum number of simultaneous couplings without requiring manual intervention. The system serves itself by detecting performance degradation and autonomously modifying the coupling limit, thus maintaining ease of operation while achieving adaptability to changing environments and load variations.
Solution Approach 2:
The system uses feedback from server performance metrics to automatically adjust the coupling limit. This eliminates the need for manual reconfiguration while maintaining simplicity, as the system self-regulates based on real-time conditions. The feedback mechanism provides adaptability without complicating operation, resolving the contradiction between ease of operation and adaptability.

AI summary
A number-of-couplings control method includes recording a first time from reception of a request transmitted by a first device to transmission of the request to a second device and a second time from the transmission of the request to the second device to reception of a response to the request corresponding to each of a plurality of requests, and changing an upper limit of the number of simultaneous couplings to the second device based on a comparison between a statistic of the first time and a statistic of the second time.
