DIL Network Bandwidth Prioritization for Mission-Critical Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Nodes in disconnected, intermittent, and low bandwidth (DIL) networks face challenges such as network delays, inefficient bandwidth usage, and asymmetric behavior due to indiscriminate data transmission across varying wide area networks, leading to network failures and outages, with network operators lacking clear monitoring and control over data transmission.
Innovation Solution
A system that manages bandwidth by monitoring and controlling data transmission, mitigating redundant data, and dynamically adjusting prioritization and network selection based on data type and network conditions, using modules like bandwidth management, mitigation, application-specific routing, and dynamic quality of service to optimize data transmission.

Engineering Contradiction Analysis
1Quantity of substance
If nodes transmit more data than the total bandwidth capacity of available wide area networks, then more data can be sent, but network delays increase and critical applications suffer performance degradation
Solution Approach 1:
The patent segments data into different classes of service (CoS) with distinct quality of service profiles. Critical applications are separated from non-critical traffic, allowing differentiated handling where critical data receives priority transmission and non-critical data can be buffered or dropped, thus preventing network delays from affecting critical applications while maximizing overall data transmission volume.
Solution Approach 2:
The patent dynamically changes QoS parameters (priority levels, bandwidth allocation) based on network conditions and data type. By adjusting these parameters in real-time, the system can accommodate higher data volumes during periods of available bandwidth while maintaining acceptable delay performance for critical applications during congested periods.
2Reliability
If quality of service profiles are configured to prioritize critical applications, then critical application performance is ensured, but network operators cannot dynamically adjust prioritization for different missions or conditions
Solution Approach 1:
The patent implements dynamic QoS profiles that can be adjusted in real-time based on mission requirements and network conditions. The system transitions from static CoS configurations to dynamic profiles that can be modified without disrupting network operation, allowing operators to prioritize different data types for different missions while maintaining reliable critical application performance.
Solution Approach 2:
The patent creates a universal QoS framework that handles multiple data types and mission scenarios through a single configurable system. The same infrastructure supports diverse prioritization needs by applying different QoS profiles to different data classes, making the system adaptable to various missions without requiring separate dedicated systems.
3Reliability
If bandwidth is allocated for redundant data transmission and retransmission, then data reliability improves, but available bandwidth for other data decreases
Solution Approach 1:
The patent applies partial redundancy by sending critical data through multiple paths or with confirmation requests only when necessary, rather than always transmitting full redundant copies. This partial action approach maintains adequate data reliability while consuming less bandwidth compared to excessive redundancy methods.
Solution Approach 2:
The patent implements selective data retention and discarding based on priority and network conditions. Non-critical redundant data can be discarded when bandwidth is constrained, while critical data is preserved and retransmitted if necessary. This selective approach maintains reliability for essential data while freeing bandwidth for other transmissions.
4Adaptability or versatility
If nodes indiscriminately utilize available wide area networks, then data transmission flexibility increases, but network failures and outages occur due to asymmetric behavior
Solution Approach 1:
The patent assigns different QoS characteristics to different data types and routes them through appropriate network paths. Critical data receives high-priority treatment with guaranteed bandwidth, while non-critical data can utilize available capacity flexibly. This local quality differentiation maintains network stability by preventing asymmetric behavior from affecting critical communications while preserving transmission flexibility for non-critical data.
Data Source
AI summary
A bandwidth management system for nodes in a network hierarchy that enables network operators to monitor/control bandwidth allocated for various types of data using existing quality of service (QOS) priorities. In various embodiments, the system may store lower priority data in a mutable queue and drop/overwrite untransmitted data (e.g., after a certain time period, upon receipt of updated data, etc.), select the wide area network best suited to transmit each type of data, change the QoS value of certain data types, and/or dynamically adjust the data prioritization or network selection based on the current mission or phase. In various embodiments, the system may also receive bulk data and distribute it locally to multiple devices, monitor the availability of each node and find the best path around unavailable nodes, and/or cache data output by a transmitting node and forward the cached data when a path to a destination node is available.
