Solution Overview

Problem

Communication networks face challenges in reliably supporting distributed real-time applications due to limited network resources, as they often cannot distinguish which applications require a minimum operable data rate, leading to potential malfunction or abortion of critical applications.

Innovation Solution

A method where the communication network dynamically adjusts data rates by determining the available bitrate and maintaining it above the minimum operable rate through resource allocation and marking IP packets to prevent bitrate drops, ensuring reliable operation of distributed real-time applications.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If the communication network dynamically adjusts data rates to maximize resource utilization, then network resource efficiency is improved, but the reliability of real-time applications cannot be guaranteed

Engineering Contradiction:

Improvenetwork resource efficiencyVSAvoidapplication operation reliability

Core Design Contradiction:

ProductivityVSReliability

Solution Approach 1:

The patent segments the data stream into periodic data packets with different priority levels. Critical real-time applications receive guaranteed bandwidth through dedicated resource allocation, while non-critical applications share remaining resources. This segmentation allows the system to maximize overall resource utilization while ensuring minimum service levels for time-critical applications.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The system dynamically changes the data rate parameter based on network conditions and application requirements. For real-time applications, the data rate is maintained above a minimum operable threshold. For non-real-time applications, the data rate can be adjusted more aggressively to maximize resource efficiency. This parameter adaptation resolves the contradiction between reliability and productivity.

Inventive Principle:

Principle #35Parameter changes

2Adaptability or versatility

If the communication network allocates network resources based on current load and connection conditions, then resource distribution flexibility is improved, but the ability to guarantee minimum operable data rate for real-time applications deteriorates

Engineering Contradiction:

Improveresource allocation flexibilityVSAvoidminimum data rate guarantee

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The system performs preliminary actions by pre-allocating guaranteed bandwidth resources to real-time applications before network congestion occurs. This ensures that when load increases, the minimum operable data rate for critical applications is already secured. The flexible resource allocation then applies to non-critical applications, resolving the contradiction between adaptability and reliability.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The communication network implements feedback mechanisms where the sender determines available bitrate and adjusts data transmission accordingly. The system continuously monitors whether the data rate remains above the minimum operable threshold and adjusts resource allocation in real-time. This feedback loop maintains reliability while allowing flexible resource distribution across multiple applications.

Inventive Principle:

Principle #23Feedback

3Productivity

If the communication connection allows data rate to fluctuate with network conditions, then resource sharing efficiency among multiple applications is improved, but the operation stability of distributed real-time application deteriorates

Engineering Contradiction:

Improveresource sharing efficiencyVSAvoidapplication operation stability

Core Design Contradiction:

ProductivityVSStability of the object's composition

Solution Approach 1:

The patent applies different quality characteristics to different applications. Real-time applications receive stable, guaranteed bandwidth with minimal fluctuation to ensure operational stability. Non-real-time applications experience greater data rate variations to maximize resource sharing efficiency. This local differentiation resolves the contradiction between productivity and stability.

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The system implements dynamic resource allocation where the degree of data rate stability varies by application type. For distributed real-time applications, the data rate is dynamically maintained above a minimum threshold with limited fluctuation. For other applications, the data rate can dynamically adjust to network conditions, improving overall resource sharing efficiency while preserving real-time application stability.
