Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If static control plane processor configuration is used, then device complexity is reduced and ease of operation is improved, but adaptability and resource utilization efficiency deteriorate
Solution Approach 1:
The patent implements dynamic process migration capability that allows processes to be automatically moved between control plane processors based on real-time resource conditions. The system monitors resource utilization metrics and triggers migration when thresholds are exceeded, transforming the static configuration into a dynamic one that adapts to changing loads while maintaining operational simplicity through automation.
Solution Approach 2:
The system employs self-service mechanisms where the control plane processors automatically monitor their own resource states and initiate migration decisions without external intervention. The processors exchange status information and autonomously determine when and where to migrate processes, enabling the system to self-optimize resource distribution while preserving ease of operation.
2Productivity
If manual configuration of processes on control plane processors is required, then device complexity is reduced, but productivity and adaptability deteriorate
Solution Approach 1:
The patent implements feedback mechanisms where control plane processors continuously monitor resource utilization metrics such as CPU usage, memory availability, and process load. This feedback information is used to automatically trigger migration decisions when resource thresholds are exceeded, enabling the system to dynamically optimize process distribution and improve productivity without requiring manual reconfiguration.
Solution Approach 2:
The system introduces an intermediary migration management mechanism that coordinates process migration between processors. This intermediary layer handles the complexity of migration decisions, resource negotiation, and state synchronization, thereby improving productivity by automating process distribution while managing device complexity through a structured coordination protocol.
3Adaptability or versatility
If more control plane processors are added to scale up the system, then adaptability and processing capability increase, but device complexity and configuration difficulty increase
Solution Approach 1:
The patent implements a universal process migration framework that can operate across any number of control plane processors with consistent behavior. The same migration protocols, resource monitoring mechanisms, and load balancing algorithms apply regardless of system scale, allowing the system to add processors to increase adaptability and processing capability without proportionally increasing configuration complexity. Each processor maintains identical functional capabilities and interacts through standardized interfaces.
Data Source
AI summary
An apparatus comprising a processor configured to migrate load from a source process running on the processor to a target process running on a peer processor in a dynamic manner by monitoring an amount of resources used by the source process, wherein the load is migrated when the amount of resources utilized by the source process exceeds a threshold. Also disclosed is a network component comprising a first processor configured to select a source process to migrate a load from the first processor based on available resources on the first processor and the source process; and a second processor configured upon receiving a migration request from the first processor to one of select and start a target process to which to migrate the load based on available resources for the second processor and the target process.
