Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If private networks are used for cloud data communication, then network performance and reliability are improved, but configuration complexity increases
Solution Approach 1:
The network system automatically performs path selection and failover based on embedded routing indicators in data packets. Branch devices and cloud gateways autonomously make routing decisions using cloud tags and transport gateway flags without requiring manual configuration, enabling the system to serve itself while maintaining high reliability through private network paths.
2Productivity
If complex configurations are performed to utilize private networks, then network prioritization is improved, but ease of operation deteriorates
Solution Approach 1:
The patent extracts the complex configuration requirements from the operational process by embedding routing instructions directly into data packets through cloud tags and transport gateway flags. This allows network prioritization to be automatically applied without requiring operators to perform complex configurations, separating the prioritization logic from manual setup procedures.
Solution Approach 2:
Routing preferences and network prioritization settings are pre-configured into the system through advertisement mechanisms that propagate cloud tags and transport gateway flags throughout the network. This preliminary action enables automatic prioritization of private network paths without requiring real-time configuration decisions during operation.
3Reliability
If network failover mechanisms are implemented, then reliability is improved, but resource consumption increases
Solution Approach 1:
The system implements efficient failover through feedback mechanisms where network devices monitor the presence and state of transport gateway flags and cloud tags in real-time. When private network paths become unavailable, this feedback triggers automatic rerouting through public networks. The feedback-driven approach maintains reliability while minimizing unnecessary resource consumption by only activating failover when actually needed.

AI summary
Techniques are described for routing traffic through an interconnect cloud gateway based on cloud traffic routing indicators. The interconnect cloud gateway can advertise the cloud traffic routing indicators, which can include cloud indicators and transport gateway indicators. The cloud indicators can include cloud tags utilized to route cloud traffic. The transport gateway indicators can include transport gateway flags utilized to identify private networks utilized to route the cloud traffic. The cloud traffic can routed during normal private network operation through private networks, which can be dynamically replaced by public networks due to occurrences of failures preventing the data traffic from being routed through the private networks and to cloud networks.
