Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Network orchestrators face challenges in efficiently detecting communication failures between network devices and themselves, especially under unreliable and unpredictable conditions, leading to delays in bulk configuration updates and inefficient management of diverse network devices with varying availability and performance.
Innovation Solution
Determine network device to network orchestrator connection characteristics such as latency, jitter, and bandwidth, and dynamically tune response timers and retries based on these characteristics to quickly detect communication failures and prioritize device management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If network orchestrator uses standard response timers and retries for all devices, then device management is simplified, but communication failure detection is delayed under unreliable network conditions
Solution Approach 1:
The patent applies local quality by customizing response timers and retry counts according to each network device's connection characteristics. Instead of using uniform timing parameters for all devices, the system measures individual device characteristics (latency, jitter, packet loss) and configures device-specific timing parameters. This resolves the contradiction by improving failure detection accuracy for each device while maintaining manageable complexity through automated measurement and configuration.
Solution Approach 2:
The patent implements dynamics by making response timers and retry counts adaptive rather than static. The system continuously measures connection characteristics and dynamically adjusts timing parameters based on current network conditions. This allows the orchestrator to optimize failure detection speed for each device while adapting to changing network conditions, resolving the contradiction between detection accuracy and time delay.
2Productivity
If network orchestrator measures and tunes configuration for each device individually, then throughput and reliability are improved, but system complexity increases
Solution Approach 1:
The patent applies self-service by having the network orchestrator automatically measure connection characteristics and tune its own configuration parameters. The system performs self-diagnosis by measuring device reachability and connection quality, then automatically adjusts response timers and retry counts without requiring manual intervention. This resolves the contradiction by improving throughput through individualized configuration while maintaining manageable complexity through automation.
Solution Approach 2:
The patent implements preliminary action by measuring connection characteristics and configuring optimal timing parameters before bulk device updates. The system proactively establishes device-specific configurations in advance, so when bulk operations are executed, each device can be processed efficiently with pre-optimized parameters. This improves overall throughput while reducing operational complexity by preparing configurations beforehand.
3Speed
If network orchestrator uses static configuration for bulk device updates, then operational simplicity is maintained, but processing speed and adaptability decrease
Solution Approach 1:
The patent applies parameter changes by modifying response timers and retry counts based on measured connection characteristics. The system changes these critical parameters dynamically for each device based on their specific network conditions, enabling faster and more reliable bulk updates. This resolves the contradiction by improving processing speed and adaptability while maintaining operational simplicity through automated parameter adjustment rather than manual configuration management.

AI summary
A method of configuring network devices. The method may include, with a network orchestrator, measuring at least one characteristic of a quality of a link between a network device and the network orchestrator during a first measurement window, categorizing the link into a connection type based on the at least one characteristic, and tuning a configuration of the network device based at least in part on the connection type identified by the network orchestrator.
