Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional network architectures are used to interconnect public clouds, then network failures and suboptimal user experiences occur due to complexity, but implementing 5G network architecture increases device complexity and infrastructure requirements
Solution Approach 1:
The patent segments the 5G network architecture into separate functional components: RAN (Radio Access Network), Core Network, and Edge Cloud. This segmentation allows each component to be independently optimized and managed, reducing overall system complexity while maintaining high reliability through modular failover capabilities.
Solution Approach 2:
The patent introduces a cloud-native core network as an intermediary layer between the RAN and edge cloud resources. This core network acts as a mediator that manages connectivity between multiple public clouds and on-premises networks, simplifying the interconnection architecture while ensuring reliable data transmission through centralized control and coordination.
2Productivity
If multiple public clouds and on-premises networks are interconnected, then data transmission efficiency improves, but network failures and interruptions increase due to connection complexity
Solution Approach 1:
The patent implements a universal core network architecture that can simultaneously connect to multiple public clouds (e.g., AWS, Azure, Google Cloud) and on-premises networks through standardized interfaces. This multi-functional core network handles diverse connectivity requirements through a single unified platform, improving data transmission efficiency while maintaining reliability through consistent connection management.
Solution Approach 2:
The patent incorporates feedback mechanisms where the core network continuously monitors the status of connections to various public clouds and on-premises networks. Based on this feedback, the system can dynamically reroute data traffic in case of failures or performance degradation, ensuring continuous reliable data transmission while optimizing efficiency through real-time adjustments.
3Adaptability or versatility
If cloud-native virtualization is implemented, then deployment agility and flexibility increase, but network management complexity increases
Solution Approach 1:
The patent implements cloud-native virtualization with self-service capabilities where the core network automatically provisions, configures, and manages virtual network functions. The system can autonomously establish connections to different public clouds and on-premises networks without manual intervention, enabling rapid deployment flexibility while reducing management complexity through automation.
Solution Approach 2:
The patent utilizes parameter changes in the virtualized network architecture to adapt to different deployment scenarios. By dynamically adjusting virtualization parameters such as resource allocation, network slicing configurations, and connectivity profiles, the system achieves deployment flexibility across various cloud environments while managing complexity through standardized parameter modifications rather than architectural reconfiguration.

AI summary
Embodiments are directed towards systems and methods for enabling an overlay network to interconnect a first public cloud and second public cloud. One such method includes: providing a connected VPC (Virtual Private Cloud); deploying one or more virtual routers within the connected VPC; connecting the first public cloud to the connected VPC using the virtual routers in the connected VPC to form the overlay network; connecting the second public cloud to the connected VPC using the overlay network via the virtual routers in the connected VPC; and transmitting data traffic between the first public cloud and the second public cloud using the overlay network via the virtual routers in the connected VPC.
