Solution Overview

Problem

The precision of modifying TCP parameters in existing data transmission methods is not high, as modifications affect all TCP streams for a user or service, leading to unnecessary changes for some users or services.

Innovation Solution

A method and apparatus that determine, based on data stream information, whether to modify TCP parameters, allowing for specific adjustments to each data stream, including sending negotiation requests to confirm compliance with preset conditions, using sockets and APIs for modification.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If TCP parameter is modified on user side, then TCP parameter in all TCP streams of the user is modified, but precision of modifying the TCP parameter is not high

Engineering Contradiction:

ImproveTCP parameter modification coverageVSAvoidTCP parameter modification precision

Core Design Contradiction:

Adaptability or versatilityVSMeasurement precision

Solution Approach 1:

The patent segments the TCP parameter modification process by introducing stream identification information (such as source IP, destination IP, source port, destination port) to distinguish different TCP streams. This allows the system to modify TCP parameters for specific streams rather than applying modifications globally to all streams of a user, thereby improving modification precision while maintaining adaptability.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent implements local quality by allowing different TCP parameters to be applied to different TCP streams based on their specific characteristics and requirements. Each TCP stream can have its own customized parameter settings determined by matching stream identification information against predefined rules, enabling precise local control rather than uniform global modification.

Inventive Principle:

Principle #3Local quality

2Adaptability or versatility

If TCP parameter is modified on server side, then TCP parameter in all TCP streams of another user is also modified, but precision of modifying the TCP parameter is not high

Engineering Contradiction:

ImproveTCP parameter modification scopeVSAvoidTCP parameter modification accuracy

Core Design Contradiction:

Adaptability or versatilityVSMeasurement precision

Solution Approach 1:

The patent segments the server-side TCP parameter modification by introducing stream identification information to differentiate between TCP streams of different users. This enables the system to apply parameter modifications to specific user streams without affecting other users' streams, thereby improving modification accuracy while maintaining the ability to modify parameters across multiple users when needed.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent implements local quality by allowing different TCP parameter settings to be applied to different user streams based on their specific requirements. Each user's TCP streams can have customized parameter settings determined by matching their stream identification information against predefined rules, enabling precise local control without unintended side effects on other users.

Inventive Principle:

Principle #3Local quality

3Productivity

If global TCP parameter modification is applied, then all TCP streams are affected, but unnecessary changes occur for some users or services

Engineering Contradiction:

ImproveData transmission efficiencyVSAvoidUnnecessary parameter modifications

Core Design Contradiction:

ProductivityVSLoss of substance

Solution Approach 1:

The patent segments the TCP parameter modification process by introducing stream identification information (source IP, destination IP, source port, destination port) to distinguish between different TCP streams. This allows the system to apply parameter modifications only to specific streams that match predefined rules, avoiding unnecessary modifications to other streams and thereby reducing wasted resources while maintaining high data transmission efficiency for affected streams.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent implements local quality by allowing different TCP parameter settings to be applied locally to specific TCP streams or user groups based on their actual transmission requirements. This prevents unnecessary global modifications, reducing resource waste on streams that do not require parameter changes while maintaining optimal performance for streams that do benefit from modifications.

Inventive Principle:

Principle #3Local quality
