Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If control plane and data plane are separated into different hardware units, then reliability is improved through independence, but device complexity and management difficulty increase
Solution Approach 1:
The patent combines the control plane and data plane into a single integrated hardware unit, eliminating the need to manage two separate systems. This merging reduces operational complexity and management overhead while maintaining the functional separation needed for reliability through software-based plane differentiation within the unified hardware architecture.
2Reliability
If control plane and data plane are separated into different hardware units, then reliability is improved through independence, but rack space and power requirements increase
Solution Approach 1:
The patent consolidates both control plane and data plane functions into a single hardware appliance, significantly reducing the rack space required compared to housing two separate hardware units. This unified architecture maintains the functional independence needed for reliability while optimizing physical resource utilization.
3Adaptability or versatility
If human intervention is used to prioritize calls during network congestion, then network management flexibility is improved, but response time and operational efficiency deteriorate
Solution Approach 1:
The patent implements automated network management capabilities that enable the system to self-monitor, self-diagnose, and self-optimize network performance during congestion events. The integrated control plane automatically prioritizes critical traffic and adjusts routing decisions without human intervention, maintaining flexibility through programmable policies while eliminating manual response delays.
Solution Approach 2:
The system incorporates real-time network monitoring and feedback mechanisms that continuously assess network conditions and automatically adjust traffic prioritization and routing. This closed-loop control enables rapid response to congestion events while maintaining adaptability through dynamic policy adjustment based on current network state.
4Reliability
If secure tunnels are manually selected for data access, then security control is improved, but automation level and operational efficiency deteriorate
Solution Approach 1:
The patent implements automated tunnel selection and management capabilities within the integrated control plane. The system automatically selects appropriate secure tunnels based on real-time network conditions, security policies, and traffic characteristics, eliminating manual tunnel configuration while maintaining security control through programmable security rules and automated credential management.
Data Source
AI summary
A method for providing data exchange using secure tunnel in a multi-tenant cloud native control plane system. A request is received by cloud control plane for accessing data. The cloud control plane provisions network connection to service endpoint at cloud provider for providing access using data plane and control plane. The control plane identifies routing information of network traffic from multiple end-user devices to establish the connection. Resiliency of the network is identified based on control plane or data plane failure and maintains the connection. Network patterns are identified for network traffic. These patterns are used by the cloud control plane to determine network policy for data access and routing. The secure tunnel is chosen from multiple tunnels based on the network policy, routing information. Data packets are forwarded by the data plane on the secure tunnel and data access is provided to the client endpoint using the secure tunnel.
