TCP Proxy Device Dynamic Mode Switching for Wireless Delay
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing proxy systems in communication networks face performance degradation and increased end-to-end delay due to the need to split TCP connections, especially in wireless local area networks (WLANs), which can lead to higher costs when mitigating these issues with high-specification devices.
Innovation Solution
A method and apparatus for a proxy device that dynamically determines system load and signal quality to selectively split TCP connections, processing packets differently based on whether the connection is wireless, thereby minimizing delay and improving network performance without passing through the application layer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If TCP connection is split by a proxy device, then network performance can be optimized for wireless connections, but end-to-end delay increases and system cost increases
Solution Approach 1:
The patent implements dynamic proxy operation mode switching based on real-time system load conditions. The proxy device transitions between normal proxy mode (with connection splitting and application layer processing) and bypass mode (direct forwarding without proxy processing), allowing the system to adapt to varying traffic conditions and minimize delay while maintaining performance optimization when needed
Solution Approach 2:
The system changes the operational parameters of the proxy device based on system load thresholds. When load exceeds a first threshold, the proxy switches to bypass mode; when load is between thresholds, it operates in normal proxy mode; when load is below a second threshold, it enables enhanced proxy functions. This parameter-based control resolves the contradiction by adjusting proxy intensity according to system capacity
2Loss of time
If high specification device is employed to mitigate delay, then end-to-end delay is reduced, but system cost increases
Solution Approach 1:
The proxy device monitors its own system load and autonomously switches between operational modes without requiring external control or high-specification hardware. The self-service mechanism allows standard devices to achieve delay mitigation by intelligently adjusting their processing behavior based on real-time conditions, eliminating the need for expensive hardware upgrades
3Productivity
If proxy operation is performed dynamically based on system load, then proxy system performance is enhanced, but system complexity increases
Solution Approach 1:
The patent implements a feedback mechanism where the proxy device continuously monitors system load metrics and uses this information to dynamically adjust its operational mode. The feedback loop compares current load against predefined thresholds and automatically switches between bypass mode, normal proxy mode, and enhanced proxy mode, enhancing performance through adaptive control while maintaining manageable complexity through rule-based decision logic
