Solution Overview

Problem

Traditional network management protocols fail to adapt to varying communication link rates in different environments, leading to excessive network overhead in contested conditions, which can leave no bandwidth for user data traffic.

Innovation Solution

The method involves dynamically adjusting the size and content of network control overhead packets to maintain a predetermined proportion with user data packets, reducing precision and excluding redundant data, and transmitting these packets only when necessary, especially in contested environments to ensure bandwidth is reserved for user data.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If traditional network management protocols use fixed overhead packet sizes, then network control is simplified, but network overhead becomes excessive in contested environments leaving no bandwidth for user data traffic

Engineering Contradiction:
Improvenetwork control protocol complexityVSAvoidnetwork overhead bandwidth consumption
Core Design Contradiction:
Device complexityVSQuantity of substance

Solution Approach 1:

The patent implements dynamic adjustment of overhead packet characteristics based on real-time link conditions. The system monitors available bandwidth and dynamically modifies overhead packet size, transmission frequency, and content to match current network capacity. In contested environments with limited bandwidth, overhead packets are reduced or suppressed entirely, while in permissive environments, full overhead functionality is restored. This dynamic behavior resolves the contradiction by making overhead adaptive rather than fixed.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system changes key parameters of overhead packets based on environmental conditions. When link capacity degrades below thresholds, the patent modifies overhead packet size, reduces transmission frequency, and adjusts the proportion of control versus user data. These parameter changes allow the network to maintain essential control functions while minimizing bandwidth consumption, directly addressing the contradiction between simplified control and excessive overhead consumption.

Principle #35Parameter changes

2Quantity of substance

If network overhead is reduced to maintain bandwidth for user data in contested environments, then available bandwidth for user data is preserved, but network control reliability may deteriorate

Engineering Contradiction:
Improveavailable bandwidth for user dataVSAvoidnetwork control reliability
Core Design Contradiction:
Quantity of substanceVSReliability

Solution Approach 1:

The patent applies partial action by providing only the minimum necessary network control overhead required to maintain basic network functionality in contested environments. Rather than implementing full overhead protocols, the system provides essential control signals at reduced levels, just enough to maintain network operation and prevent complete failure. This partial overhead approach preserves bandwidth for user data while maintaining sufficient control reliability.

Inventive Principle:
Principle #16Partial or excessive action

Solution Approach 2:

The system implements feedback mechanisms where nodes monitor link conditions and adjust overhead transmission accordingly. When degradation is detected, the system feedback-reduces overhead transmission and when conditions improve, overhead is restored. This feedback loop ensures that network control reliability is maintained at acceptable levels while optimizing bandwidth availability for user data based on real-time environmental conditions.

Inventive Principle:
Principle #23Feedback

3Productivity

If network protocols adapt dynamically to varying link rates, then bandwidth utilization is optimized across different environments, but protocol complexity increases

Engineering Contradiction:
Improvebandwidth utilization efficiencyVSAvoidprotocol adaptation complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent segments the network operation into distinct modes based on link conditions - permissive mode with full overhead functionality and contested mode with reduced overhead. By segmenting the protocol behavior into discrete operational states rather than continuous adaptation, the system achieves dynamic bandwidth utilization without requiring complex real-time calculation and adjustment mechanisms. This segmentation simplifies the adaptation logic while maintaining productivity benefits.

Inventive Principle:
Principle #1Segmentation

AI summary

Sending network data. A method includes transmitting data on a communication link, in an environment. A network control overhead portion of the data is allocated to network control overhead data packets for controlling how data is transmitted on the communication link. A user data portion of the data is allocated to user data packets for transmitting data between users of nodes on the communication link. A change in data capacity of the communication link is identified. As a result, a change is made in the network control overhead portion of the data, changing at least one of frequency of network control overhead data packets or size of network control overhead data packets to attempt to maintain a predetermined proportion factor for the network control overhead portion as compared to the user data portion. The network control overhead portion of the data is transmitted according to the change.
