Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The interconnection of large domain network controllers to create a bigger network can adversely impact network performance due to the sharing of large volumes of data, leading to management challenges and inefficiencies.
Innovation Solution
A communication framework that allows specifying constraints for network controllers to control and limit data communication with other controllers or applications, using filters, rules, and dynamic criteria to determine permitted data exchanges, thereby preventing unnecessary data sharing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If large domain network controllers are interconnected to create a bigger network, then network coverage and functionality are improved, but network performance deteriorates due to large volumes of data being shared between controllers
Solution Approach 1:
The patent segments the data shared between network controllers into different categories (configuration data, state data, performance data, etc.) and applies different constraint levels to each category. This allows essential data to be shared for network functionality while non-essential data is restricted, thereby maintaining network coverage while improving performance.
Solution Approach 2:
The patent implements location-aware data sharing where data is shared based on the geographical or logical proximity of network controllers. Controllers in the same regional domain share more data than those in different regions, optimizing the balance between network coverage and performance by reducing unnecessary long-distance data transmission.
2Loss of information
If data sharing between network controllers is unrestricted, then complete network visibility and control are achieved, but data management complexity increases
Solution Approach 1:
The patent establishes data sharing constraints and policies in advance before data exchange occurs. Administrators can pre-configure which data types are shareable, the conditions for sharing, and the recipients. This preliminary configuration reduces the complexity of real-time data management while maintaining necessary network visibility.
Solution Approach 2:
The patent introduces a data sharing intermediary layer that sits between network controllers and manages data exchange according to predefined constraints. This intermediary automatically filters, transforms, and routes data based on policy rules, reducing the management burden on individual controllers while ensuring proper data visibility where needed.
3Reliability
If all data is shared between interconnected network controllers, then comprehensive network monitoring is enabled, but network efficiency decreases due to unnecessary data transmission
Solution Approach 1:
The patent implements partial data sharing where only the necessary subset of data is transmitted between controllers based on their specific monitoring needs and roles. Instead of sharing all data universally, each controller receives only the partial data set relevant to its function, maintaining monitoring reliability while reducing energy consumption from unnecessary data transmission.
Solution Approach 2:
The patent makes data sharing constraints dynamic and adaptable based on current network conditions, controller workload, and monitoring requirements. The system can adjust the level of data sharing in real-time, increasing visibility when needed and reducing transmission when not necessary, thereby optimizing the balance between monitoring reliability and energy efficiency.

AI summary
A communication framework is provided that can be configured to control or limit a network controller's ability to communicate, export, or share the network controller's data with others, such as with other network controllers in the network environment. As part of this framework, techniques are provided that enable constraints to be specified for a particular network controller, where the constraints control and limit the data that is permitted to be communicated from the particular network controller to other network controllers or intended data recipients in the network environment.
